ATB Nano One review

[reeftivo]

been on vacation for a while. just returned & the skimmer is chugging along great!

I lowered the speed a click prior to leaving (nice option to have) and cup was right around 3/4 full (whew! close one!)

It's promising to hear you have been trouble free (PRDubois) for such a long time. I see no issues with this pump so far and the silence is wonderful.

Only issue I've found on mine is that if I run the air draw through the silencer, I have to run water through the air line weekly because the internal skimmer level rises as if the intake at the volute/venturi is clogging a little. Water clears it right up and it goes back to normal levels. I decided to just remove the silencer and now there appears to be less restriction and the internal level stays put. I can hear the air draw now but it isn't noticeable for me when the cabinet door is shut, so I'll leave it like that.

I stated i would get some air numbers and now that I'm back I will get out the old Dwyer in the next coming days.

Loving this skimmer so far!!!!

Good to see that they are still taking the time to weld all of the joints. Great job ATB.

I now have a lot more room since my little modification. However, $400 isn't feasible for me with a kid on the way so I will look elsewhere. I used to have an 840 but the tank never came about. I just ran it in some saltwater for a few days to see how everything worked. It was a piece of art!

Does it perform better than the Reefdynamics 80 and did the 80 you were using have a Sicce pump?

Thanks for the write up!

Definitely curious on the air intake. 1200 lph seems massive for that size skimmer and neck.

I would give the edge to the 80s in concentrated skim. The 80 has a bigger/taller reaction chamber, but a narrower neck which produces a nasty foam head on my set up. The nano one has a big neck for such a shorty at almost 4 inches. If I feed heavy the nano one responds a lot faster than the 80. The 80 would drop the foam head about 30 minutes and the ATB will kick in in about 10 minutes. I would attribute this to the smooth rise of bubbles with atb. The 80 is turbulent since it has no bb plate. Air numbers soon. :-)

[reeftivo]

Oh and yes, the 80 runs a sicce. Sorry forgot to add that

[reeftivo]

Okay, let's do some numbers

As you can see is skimming very well
20170210_213044.jpg

Level 1 =19scfh/538lph
20170210_213613.jpg

Level 2=20scfh/567lph
20170210_213727.jpg

Level 3=22scfh/623lph
20170210_213756.jpg

More to follow

[reeftivo]

Level 4=24ish/680lph
20170210_213831.jpg

Level 5=26/27ish-/736 to 764 with slight bounce
20170210_213904.jpg

Level 6= no change

Level 7=28scfh/793lph
20170210_214026.jpg

Level 8=29scfh/821lph
20170210_214057.jpg

[reeftivo]

Shoot, just noticed these are loading sideways,ARRG!
sorry, using my cell but you'll very the idea.

Level 9=29scfh/821lph
20170210_214103.jpg

Level 10 pic is missing but I'm too lazy to go back down stairs and snap another pic
Scfh on 10 bounced a little between 30 and 32/849 to 906lph

Other than a couple levels where I had some bounce, the draw was smooth.
The numbers are lower than the specs state but i'm running mine at 7 inches and I didn't give more than a couple minutes between adjustment for the skimmer to settle in. The draw will change a little with more time at each setting.

I can't see this skimmer being run at anything above 8. The neck is just too short. Running it without the cup at level 10 would be fine if you need to blast a critter up and out.

I'll try it later at different sump levels to see if I can achieve the 1200. I think it will do it if it's run at 8 inches

It would be cool if atb offered a cup with longer neck as an option

[reeftivo]

too late to edit but i just realized how mentally challenged i can be at times.
there is no 9 and 10 power level.
level 6 was 793
level 7 was 821
and level 8 was roughly 906

i had some double pics on my cell that threw me off and i was counting pics.

sorry for the brain FFRRTT.

Agreed. This is an awesome looking skimmer but I'm concerned about the pump. Great review by the way

[abhishek@1985]

Any update on the skimmer ? Am considering it to replace my Deltec sc1351 with this one over a heavy loaded 100 gallon system .
Any thoughts ?

Regards,
Abhishek

chugging along fine on my office 75. Took it offline at the house because i put in an aquafuge to hold more LR & matrix and the bracket for the dang aquafuge stuck out too far.
Really solid skimmer but many are skeptical of the long term performance of the Jecod pump. No issue with mine to date!

[reeftivo]

Update, nano one is back on line at the house and loving it. I had some serious crazing on the RD 80s and I have a turbos aquatics L2 scrubber in the que. The 80s was not going to be a good fit from where I need to mount my future scrubber. The atb is going to work fine. It's chugging great and I will keep updating on pump performance.

Happy reefing

[E.intheC]

Good to hear -- is the pump still acting normally?

[reeftivo]

yes, still starting up fine. The soft start is nice but I'm keeping an eye on it the longer it runs. I have ran another DC skimmer in the past with soft start and had to coax the impeller a couple times to get it started. That skimmer had a waveline labeled pump though.

Hope all is great Eric!

Happy Reefing

update

last night realized i may have to put the silencer back on since the noise from the air draw is more audible than before. I need to get the meter on it since it may be pulling more air now that it has been broken in a while and is getting fed better on the current system. I ran the silencer when i initially broke it in, but removed it since i like feeding hot RO water through the line during WCs and it makes it easier. I'll post a skim shot tomorrow. I'm sure there isn't a lot of interest in this skimmer due to the price tag and the pump, but it is a super performer and if the pump stands the test of time, it will be well worth the money for me.

another note; For those that run a skim locker, this skimmer doesn't have a secondary drain fitting on the cup. I would drill it myself but the skimmer cup sits so low in the sump that unless i raise the skimmer and increase my water level in sump, it is not doable for me. Others may be able to though if they can put it on a stand and get it high enough.

All is well, thank you! I have a 5 month old daughter and I brought her downstairs to see the fish the other day. Her eyes lit up and she pointed at them. Pretty cool!

Regarding the skimmer - that impeller issue reminds me of the old Sicce 2500 pumps- they would not reliably start again if the power went out or if they were turned off for feed mode. The Sicce 1000 pumps had no issues like that. It's honestly disappointing that ATB is using such a low quality pump. Nice that the skimmer is reasonably priced but the pump is making me cautious.

[reeftivo]

glad to hear the little one is taking a liking to the tank. The pump has not failed me yet but i'll report if it does. the impeller i was referring to was from a different skimmer pump.

this is the best performer i've used yet.

Happy Reefing and happy new year!

[reeftivo]

promised a pic

took last night. A little over two full days

atb nano one 2 days 1-10-18.jpg

always have to clean skimmer cups in the restroom. A mandate from the wife ever since she almost threw up on two separate occasions when I did cleanings in the kitchen.

oh well, happy wife happy life

Thanks for the pic- it's likely down to a decision between this skimmer, the Vertex Omega 150, or possibly a higher end Octo skimmer. Need to research that line more.

[markalex]

Thinking about going for one of these,been a while but hopefully its still running well

[reeftivo]

Great skimmer. No problems at all. Very quiet and chugs.

[Mike de Leon]

Still going strong? Would this be enough for a lightly stocked 120? Thanks in advance.
