So I've got a case of what I believe may be velvet due to cross contamination in a FOWLR tank and have been planning to go fallow but was wondering if anyone has tried or think it's worth a try to manage velvet with a canister filter that has a UV built in? Also helping the case is the fact that I just added a load of ocean collected live rock which we all know has a ton of probiotic bacteria all over it. Since this could help boost the fish's immune system, not only would the canister filter be reducing the free swimming parasite population but the fish would also be able to fight it off naturally. (at least in theory) What do you guys think about this idea?
