Makes sense:redface:and that does explain why the antibiotic makes it appear to disappear for a while.

It's to bad we can't keep Crassostrea Virginica (eastern oyster)in a reef tank....or can we?

i dont think chemiclean is going to help , i mean you did it once right and look what your left with.

have you looked into dosing h2o2 to your tanks alongside with blackouts, seems to be working for some folks on RC.


personally i would start treating for dinos and forget the chemiclean.

im almost positive your dealing with dinos.

possibly look into adding/dripping kalk or limewater and getting your ph rasied and stable.

good luck!!

Just out of curiosity, how old is your tank?

Tank is almost 2 years old. But has been moved. I'm not thinking diatoms.

I tested phosphates this morning with lights out and they were .07. So they were definitely up from during the day.

So my plan is to do another water change this morning. Wait a few days, do another round of chemiclean with the ensuing water change. The box does say you may need multiple treatments.

If that doesn't kill whatever I'm dealing with then we'll start down the Dino route.

Also I run my cheato light at the same time as my main tank, should I run it at opposite times?

When u decided to finally try peroxide go to a horticulture store. You can get it there at 35%

Thanks I was wondering where to get the stronger stuff.

Just be aware that Scarlet Skunk Cleaner Shrimp do not tolerate H202 exposure well: they are one of a few "intolerants." You didn't specify what kind of cleaner shrimp you have.

I routinely use 3% for 10 minute dips (1:10 H202 to tankwater), and I've had very good success with it. For dipping corals I would stick with the lower concentration. If you'll be dipping your rocks, then I would use the 35% as it will stretch farther.

It is a scarlet skunk cleaner, had to google that.

I'm not going down the h2o2 route yet but will post if I do. If you dip your rocks in it won't it kill all the beneficial bacteria as well?

im not talking about dipping though im talking about dosing straight to your system.

along with this low temps and a lengthly blackout are required.....some are doing up to 10 days.....coral has to go for this.
