Will paraguard affect my saltwater aquarium's biological filtration in any way? Also, I'm planning on dosing directly in my FOWLR(No Invertebrates). Will it permanently contaminate my sand & rock? Will sufficiently large water changes do the trick? Another big doubt I have in the product is the fact that all the directions say is to keep on dosing unless your fish don't stress. That can't be right, I mean some fish show no signs at all & then suddenly die so it sounds very risky to just keep dosing. Their should be maximum period for dosing I'm assuming. Could you please shed some light on the matter. Thanks in advance.

Re: Paraguard On Bacteria & Dosing
Hi Patrick,
Normally, using ParaGuard as directed doesn't effect the bacteria in the biofilter. The active ingredients break down after about 24 hours, so you don't have to worry about it accumulating. It does contain some malachite green, which has the potential to stain silicone in some cases though it usually doesn't. I've never heard of it staining rocks or sand and have used it with many different kinds.
The regular dose is well tolerated by most fish and it can be dosed daily. If you are treating particularly sensitive fish, you can start with a half dose and increase to a full dose only if the fish in question show no signs of stress. It is true that fish can suddenly die without warning, but normally you see signs of stress well before that happens. The length of treatment is going to depend on what you are treating. For flukes, it may require 3 weeks to eradicate an infestation. For ich it might take 2-3 weeks. For Cryptocaryon (marine ich) it take 3-6 weeks or more to completely eradicate an infestation. For most fungal or bacterial infections treatment only needs to continue until symptoms clear up. -
