Yes I have live plants, otherwise I could just get the good old "algae be gone" tablet thingies. I also have invertebrates. So double no no on the tabbies.
Thanks for the flourish info. I was hoping to find it local because my algae is reallllly bad. Was fine when it was cycling, because I had a million snails. But it's a puffer tank and they ate all the snails, lol. I only have 2 shrimp and an otto in with them, and they don't work fast enough.
Besides, ottos don't eat green algae, which is getting pretty bad in the tank. The brown algae is a lesser problem.
Thanks Daveedka, will look at Big Al's as well.
