Glad to hear. Maybe do another water change in the morning.

In the future I would try to avoid panic reactions like that.

IMO you only treat for what you know to be happening, not what you suspect. Treating a tank with anything without proof that there is need is dangerous....as you found out.

If one fish has already died I would do a much larger water change.....like 30-50%

Quote from the Tremco data sheet...

'PROglaze is not recommended........in continuous submerged applications'

Not sure why?

I would stop using that sump ASAP... I do recall that silicone is meant for windows and not aquarium use...

pure silicon is fine and is what is required to build fishtanks.
why most silicones are dangerous is because they have anit-mold additives which will kill your tank.

Would that be the reason my tank is cloudy. The silicone does not say it inhibits mold. And does not say on it that it can not be used for water applications.

[howdy20012002]

I would call Tremco and call them to find out about its use and see if it contains anti-mildew.
from what I understand, most tubes of silicone contain anti-mildew addtives.
general rule of thumb for silicone, don't use it unless it says safe for aquarium use.
it is just not worth the possible problems to save a few bucks.
also, I don't know how long you let it cure..that could be problematic as well.

I put water in it last Tuesday 4-5 pm. And changed the water 5-6 times. Leaving water in it over night. Then I put it into use on Friday night around 7. Or so. I also plumbed a new reactor as well. With GFO in it. That is the only change that was done besides the new sump!! By the way all the fish made it except 2. I have my skimmer and 3 small bags of carbon going. Hoping to get it to clear up and remove any contaminants. I have done 2 water changes. 15 gallons a peice. I have a 120 gallon tank. Don't want to take too much out with the fish recovering.

Herbatana can kill fish for sure. One person in the reefaction forum recently lost most of her fish to this treatment. It is removing oxygen from the water so proper aeration is very very important.

Plus it is a treatement that is not efficient so no point using it. There is no reef safe treatement that will be efficiently killing parasites.

Be very carefull with Prime and using medication because Prime can bind with some med. Prime remove oxygen from the water at high temperature and herbatana as well. There is not a lot of oxygen in 5 gallons of water, even without med.

For exemple, you cannot use Cupramine with Prime as it will bind with the amine in Cupramine and will release copper into a toxic form.
