Hydroids, how to get rid of them - Page 2

djultra · 12/13/2005, 04:36 PM

I did notice that my blue legs seem to eat the head off of them but they seem to come right back. Maybe if I put a whole lot of blue legs in my take, they would keep them under control

I have tried kalk, peppermint shrimp, naso, angels, pencil urchin, limpets, crabs. All to no avail. I have five tangs in my tank, two dwarf angels, foxface, two pencil urchins, limpets, carbs, and snails, none of them will touch this stuff. I had about ten peppermint shrimp in the tank that didn't touch them, but in all fairness, they didn't have much time to work since my flame hawk found them tasty. This stuff is a curse. I am going to remove the effected rock, but i have the stuff growing on the back walls of the tank. I haven't figured out how to get rid of those yet.

yeah i just learned i gotthese friggers and i'm going to war tomorrow. i cannot take LR they're on out, it will mess up my intricate aquascaping. seems like nothing is gauranteed to eat them. i read boiling rodi and shooting them w/ a syringe works. that seems not so bad. i'm gonna try tomorrow. i don't have them bad yet. need to take care of them pronto. probably will get 2 pepp shrimp tomorrow too just to try.

Good luck, I hope it works for you. If you can't take the rock out, make sure you don't mess a hair of them or you will lose the battle. I never had any luck with finding a predator for these things. After at least two years fighting these, I am losing this one. These things have overran and killed several corals in the last six months or so and now cover at least 50% of the rock and back wall. I have finally resigned to start removing rock from the tank and kill it. I hate to do it and I will probably loose a few corals in the process, but if I can get rid of these it will be worth it. If I didn't need so much rock, I would toss it out and buy all new rock, but that would cost way too much.

So far I have removed a few pieces and placed them in RO water for a week. Then scrubbed them with a hard bristle brush, rinsed with a hose and now have placed them in a garbage can of salt water. I placed a PH in the can, but no heater and no light. I will try keeping it in the dark for a week or so and see how it does.

The next batch of rock I will try removing it from the tank, cover it in kalk paste for a day, hose that off and scrub the rock, then place it in the garbage can of salt water. Hopefully that will work.

That would be an under statement. I wouldn't wish these things on my worst enemy. When I up graded to a larger tank about seven months ago, I removed all the rock that had the hydroids on it. I then proceeded to reomve the hydroids by scrubing them and using kalk before I placed them back into the tank. This method worked great. Unfortunately, the was a small colony about the size of a quarter left on one rock that had numerous corals attached also. I didn't think it would be that big of a deal to go ahead and place it in the tank ( so I could save the corals) and I would just apply the kalk to the rock in the tank. Well today, my live rock is at least 70% covered and they have spread to a large portion of the back wall and overflows. As I said in an earlier post, these things are the spawn of satan.

my sallylight foot ate mine

Ive had these in my tank for a couple weeks now and had no idea they were so bad. Im definaly going to town on these things. I think Ill flaten a piece of epoxy, smear superglue on the back side and seal cover them up permanatly. I would think they cant spread if there tenticles glued down.

DMK · 01/15/2006, 01:10 PM

i managed to get rock out and boiled it. they were on another rock nearby, only a few. i simply injected them w/ a mix of boiling water and alkalinity part of bionic-DONE!. hopefully.

Lunchbucket · 01/15/2006, 01:48 PM
