Hi all I saw in the store today Aquarium Pharmaceuticals, Inc. Algea Destroyer tablets and I was wondering if anyone has any input about them.

I would highly suggest against them. They have a tendency of destroying the cycling of the tank

i only use them in my (uncycled cos it's too small) betta tank. they do a *reasonable* job, but not terrific. i think they are basically tablets containing copper sulphate as the active ingredient.

I have had a great deal of success with the Algae Destroyer LIQUID. You need to shake it very very well, and I would suggest using no more that 1/2 tsp per 10 gallons - half the recommended amount - that seems to do a fine job. I have only used it when I have a totally green tank with suspended algae - the attached algae on the sides and such should be left or mechnically removed - it is so easy to do so. I would not trust the tablets not to leave pockets of tank that had too high a dose of the herbacide in them, and places that had too little. And what if the fish ATE the silly thing?! I mix the liquid up very well in replacement water, before adding it to the tank. STIR it well.

The Algae Destroyer has never disturbed my cycle. I have used it every week for a while in a large tank that was holding 8-10 inch fish. That tank was green and totally thick with algae and the cycle remained very strong and robust even with weekly additions. It was sitting outside and was very green but needed to be clearer to support viewing the fish.

I do think that it is something that should only be used when you have no other options. I have used it as an "emerrgency" additive when a tank just HAS to look good for various reasons and it works, but generally, you would not want to add an herbacide to the water any more than necessary. It will kill all the good green algae that processes the nitrates for you, also.......

unnecessary items,
i'd suggest you fix the problem(s) that cause the algae, i.e. too much light coming into the tank, too much nutrients (nitrate).
or simply do more water changes..

try your best not too add more chemical into the water.
