unwanted phyto bloom.

[block head]

i'm pretty sure i contaminated my son's tank with some phyto(nanno). it's a Fowlr w/sand. lg water changes (50%) and lights off for days have no effect. i tried using algaefix at reccomended doseage. after 10 days i didn't seem to be gaining ground. it only has a pair of bangaii's in the tank. any tips on how to crash the culture with chemistry? finding rots is a pita, i'd rather avoid if possible. thanks:headwally:

phosguard?

i think that could work, pretty sure i've got some lying around.

If you don't have any photosynthic corals or algae your looking to keep alive, a week in total darkness will do the trick. When I say total darkness, I'm talking no lights and wrapping the tank with paper or cardboard to the point of absolutely no light penetration for a good 7 days. This will usually kill of all but the most stubborn algae blooms.

When I had a massive phyto bloom the only thing that worked was to hook up a UV sterilizer, with 2 days the tank was crystal clear.

I over-nighted a UV unit with my phyto bloom then put in new carbon. The carbon cleaned it up before my UV got there the next day. Food for though?

hmm , carbon, phosguard combo ? or pull my fish and blackout for a week ? i'm thinking both.

Carbon,Phos will do diddly,you'll waste time and $$$.
You need to either borrow a U.V. or buy one.
Even water changes wont do anything.
Had this happen in a QT tank once while running hypo.
