hi,

my fish came down with a case of ich. tank is a 5.5 low-tech, no carbon, ferts every once in a while, 13w cf (50/50), turface substrate.

i had some beard/thread/hair algae (can't differentiate) growing on some turface grains and at the base of e. tellenus.

anyway, i treated with the new maracide. it is malachite green and chitosan. says it is safe for plants, but recommends using a hospital tank. it initially tints the water a light blue, but clears up after several hours.

followed directions, 1ml/gal. dosed it after lights out last night. today, i notice that the b/t/h algae was gone in all locations. java moss, e. tellenus, hygro, anubias, and crypts were not affected, nor were ghost shrimp. anecdotal, but encouraging

i have another tank that has some b/t/h algae, but i don't want to stress the fish in there. if it gets out of hand, i may have to treat to save the tank.

i also had to treat my main tank, 30 gal, 72w cf, press co2, ei methodology. no b/t/h in this tank to begin with. after first treatment, none of the plants appear to be affected including val nana, anubias, glosso, ludwigia inclinata, l. brevipes, l. ovalis, java ferns (reg and windelov), rotala rotundifolia, r. wallichi, water sprite, crypt wendtii red, hygro, l. aromatica.

From the article:

So... is the use of Malachite Green "worth it"... That is, worth the risk of poisoning your livestock... A qualified "yes", particularly for freshwater and pond use... for fungused eggs for production facilities of these fishes, common ich and velvet problems... But not warranted IMO in marine applications... Just too dangerous IMO, easy to make mistakes with with seawater use. Better to stick with tried and true copper formulations that can be tested for, and have a bit wider efficacy.

if you have ich, they recommend treating the whole tank because the ich is everywhere, not just on your fish.

there are safer ich meds... There's a Jungle ich med something or another.

hyposalinity is a MUCH more effective and less stressful treatment for cryptocaryon (sp?) than copper. i always use hyposalinity before introducing a fish into my reef tank.
