Help Needed Urgently! Tank Crashing...

So my tank is nearly five weeks old. It is 65l has no fish and is stocked with mushrooms, a few zoanthids, a colt coral, an anthelia and a single hermit crab. There is 10.4 kg of rock filled with invertebrates. The lighting is 150w Metal Halide

So a week ago we had brown out which destroyed one heater, and the 600l/ph pump. The heater was replaced the pump removed leaving a 950l/ph pump and a 250l/ph pump neither of which worked well but it was still running while I waited on replacements. I also pulled the skimmer down as it wasn't skimming much (fishless tank, not fed much)

A few days ago the tank went cloudy not long after i noticed Magnesium was at 1110ppm, Alkalinity at 100ppm and Calcium at 320ppm. Over a couple of days I buffered Magnesium to 1400 ppm, Alkalinity to 170ppm and Calcium to 380ppm.

However I just went to look at the tank and the various hitchhikers were scattered across the bottom dead mainly worms, chitons and crabs. My hermit crab seems okay and all the feather dusters are extended. The corals don't seem overly happy but their not miserable either.

I'm running ammonia, nitrate, nitrite and pH tests at the moment but really can't work out what happened. I've done 8l water changes weekly and checked the parameters often and never got any problems ammonia, nitrite and nitrate were always at 0, alk/calc/mag were always a little low but not aweful.

Help please!

I don't think so, some little flying bugs did get into it the other day but I can't see them being enough to hurt the critters. I'm just getting the new canister online now filled with a heck of a lot of carbon and some filter floss so I can remove the pumps in case of stray electricity.

Ammonia-0
Nitrite-0
Nitrate-0
pH- 7.9
Temp- 25.2 celsius
Salinity- 1.027

All I can think of is something chemical? it seems to have only hit the smaller inverts, I caught a little 2cm shrimp which is fine and Dandy the hermit crab is also totally fine.

Water seems to be clearing a bit now and the corals are extending. Normally I'd think corals were more sensitive then invertebrates, guess not...

How long was the heater out before it was replaced? And What did the temp get too?

Also, if the temp was low, how quickly did you bring it up with the new heater?

I think the best thing to do is wait. Maybe run some carbon if you can. And put the skimmer back in play. It was providing oxygen even if it wasn't pulling out skimmate.

Keep in mind that sometimes stability is more important than exact numbers. If you find one of your parameters out of line, don't rush into changing quickly unless it is really an emergency such as an ammonia reading. Often times the critters we keep in aquariums can handle poor water quality (not that yours is bad) better than they can handle rapid changes.

I was only running the skimnmer during the day and noticed problems with a pH that was rising and falling too much so took the skimmer down. I'll start it back up tomorrow but can't run it during night time.

The old heater kept temp at 22 but wouldn't go higher no matter the setting. It was replaced maybe 48 hours after it stopped working as it took me a bit to realise.

I think their may be a problem with electricity still as I was checking temps tonight and by 10 pm (an hour after Halides turned off) temp had dropped to 23 and the heater was doing nothing. I spent some time fiddling but it would only stay on for ten minutes. I've put in another new heater a 200w one this time and am staying up (nearly midnight here) watching it, without a functioning heater temp can drop to 15 degrees easy, it's freezing here. Strangely though the 25w heater in the water change bucket which is plugged in to the same board is running fine keeping the bucket at 26. Perhaps just shoddy equipment I'm saving for a quality inline heater but its gonna take awhile.

The Mag/alk/calc buffering was done slowly on a drip system (1 drip every 5 seconds) and diluted well with the top off water i didn't think it would make much of a difference.

I have a kg of carbon in the canister which I'm hoping will help.

Heater lasted for all of twenty minutes, moved to a new outlet and managed all of five minutes. I've now run an extension cables across the room and plugged it in, kinda doubtful it will work though. I'm tempted to set it at 28 in case it just has a dodgy thermostat but if it actually heated the tank to 28...

I'm just going to leave it for now I'm so tired and I have to be up early tomorrow. I'm really questioning why I wanted a reef tank now, it was nice and all but really why can it never just run?

Although you did a slow drip of the calcium, etc. what is the total amount (ml) you added of each to increase your levels? Did the cloudy water look more like it had dissolved stuff in it (like a blizzard)?

Is it the equipment or your location?

I would throw in a bag of carbon to soak up some of that excess stuff.

Check for stray electricity (you can use a grounding probe to bleed off any leaking current).

Why cannot you run your skimmer at night? This also helps airate your water.

I think you have just had a run of bad luck. What equipment do you have (brand also - not all equipment is equal, some are more reliable than others).

Also what size is your heater? You probably need at least a 100 watt heater. You need water current over it or it will just heat up the water around it and shut off.

To be honest it sounds like you either need new equipment, or possibly your home's electrical cannot handle the needs of a fishtank. That would be kind of odd, but heaters shouldn't be breaking like this.

Invest in a titanium heater I think there like 25bucks.....I had a glass one go bad it cracked and it took me a week to figure out what was poping the breaker outside......after googeling heaters I read numerous stories of houses burning down due to faulty heaters....something to think about anyways......luckly I live in the desert so I don't use one at all after my incident..

Re: Help Needed Urgently! Tank Crashing...

Hi,

You mentioned that your tank went cloudy. This sounds like a bacterial bloom and I'm suspecting that (along with the absence of a running skimmer) it had depleted the oxygen in your tank, which in turn killed the inhabitants.

A side note-- if you're only keeping mushrooms and various softies, I wouldn't worry much about Mg/Ca/Alk. A small but frequent water change should take care of all the levels for you, as long as you watch your salinity and temp.

And since your tank is only five weeks old, it've very possible that it's on its last stage of cycling-- in my experience this is the most tedious stage of the cycle because of die offs. My suggestion is to just run some carbon and do a small water change, but be patient. The system should self-adjust.

good luck

Can't run skimmer at night as it sits next to my bed and my parents are able to hear it just as clearly as I do and it ends up keeping everyone up at night.

I replaced EVERYTHING after the brown out, I pulled all the old pumps replaced with a canister and replaced the heater. The heater is 100w Aqua One, I've added in a 200w Aquaworld heater to keep the temp at 26 since the 100w seems to be struggling. The canister isn't a branded canister it's German Design does 1000/lph, I got it yesterday.

Titanium heaters aren't exactly easy to come by and would set me back $70-100 here, the same price as a quality inline heater.

The tank never went through a cycle, I used cured liverock which was transported in water, I did have a brief algae bloom of hair algae which the raised magnesium killed off but that's all, which may have started a cycle again.

I've added a filter in with a spray bar pointing at the surface, I forgot my skimmer's missing parts (electrical bits got fried from the brown out like everything else) so can't run it. I can add just an airstone though. It would explain why Dandy my hermit Crab is staying so close to the surface.

Doesn't seem to be too many new deaths today though there are some sad ones, my two hitch hiker pistol shrimp and my sand crab. However my Eunice was out on the ground so I finally managed to catch the little bugger.

Just did an 8l water change and siphoned all the dead bodies out, also managed to cause a rockslide but anyways. The light turns on in an hour so will be able to see how all the corals extend etc then.

If it is the venturi tube on the skimer gurgling, there is an easy fix for that. You can make a silencer out of two pvc caps and a short piece of tubing.

Here is another type even cheaper. I can't vouch for this type, but it seems to be pretty similar in principle.

http://www.nano-reef.com/forums/inde...owtopic=168424

the pvc one is basically just a short length 1" pvc pipe and a cap on each end. drill a hole in each end and shove the venturi tube most of the way in. Take a short length of airline and shove it most of the way in the other end so their is overlap. I did this on mine and it is basically silent now. gurgled like mad before.

My Skimmer is air driven, it's the airpump and bubbles that drives everyone insane. We live in the country and night times are virtually silent, anything that hums is ten times louder.

Just did another 8l water change, the water seems to be clearing slightly and there weren't any dead bodies on the bottom this morning. The corals still don't look great though, my hitchhiker colt coral has it's polyps it but is drooping, the same for the hitchhiker anthelia. Some shrooms started to expand as soon as the light turned on and the favia/favite is nice and puffy but a couple are still shriveled.

Should I just keep doing daily waterchanges or just let it settle for a bit now? Ammonia, nitrite and nitrate are still all sitting at 0.

Bugger Ammonia's risen to 0.1, all the detritus has been removed but obviously not fast enough. I'll keep an eye on it in case it rises further, but it should drop within a couple of days right?

LOL I know the feeling. After the wife and I got back from our deployments in Iraq the house seemed deafenningly quiet. We went from 15 mo of non-stop generators, A/C units, helocopters, gun fire, explosions, etc to the occasional A/C here.

Just wait until you get use to it. When I had my 180-gal and I woke up to silence, I would have a panic attack thinking all my pumps died (either burned out from no water which may be on the floor or no electricity). Luckily, my tank could go about 16 hours without elec but would still freak me out.

If your tank is cycling again it could take a week. I think you may need to run the skimmer 24/7. The skimmer not only cleans toxins out but provides oxygen as corals use up oxygen at night and CO2 during the day (same as algea).

To combat the noise you may need to set up a sump with the skimmer in a cabinet or move the tank to an area where it will not bother you at night.

Do you have snails? Any missing? You would be amazed at the damage one dead astrea can do to a tank if left to rot.

I can't move the tank, or add a sump and the skimmer is wrecked (long story). Ammonia's risen to 0.25

The only moving invert I've added to the tank is the lone hermit crab and he's still wandering around. However this tank has some mega bristleworms (i've pulled a 13" one out, and three 6" ones) and one must've died in the LR, well that's all I can think of since there's certainly no dead bodies anywhere else that could produce ammonia.

Just hoping the corals make it through, the favia/favite had it's feeders out last night and seems fine but the softies seem less then happy.

Were the bristleworms dead? If not leave them in the tank as they will eat the detritus and excess food. I have never seen my bristles eat anything that was alive.

The large ones were removed because being a nano tank I couldn't support them so they went back to the LFS. There were some dead ones but their are plenty small ones still alive in the rock.

The water cleared and levels all dropped back to 0 and I now have a wonderful algae bloom, and here was me so happy I got away without even one when I added the LR. My Anthelia hicthhiker dissappeared over night and the colt is dropping branches, but they were both hitch hikers so it wasn't really that big a loss. I'm going to go at everything with a turkey baster tonight and get the last of the gunk into the canister so tomorrow I can disconnect the canister and remove everything but the carbon before reconnecting.

I think it's all stable, but will leave it for a bit before adding more corals.
