The bacteria culture is AquaLife Activate. They had a couple of other brands, but don't think they had any you mentioned. I added a dose to each tank on Sunday. Monday's testing revealed ammonia had gone down but the nitrite level was still high, so did 2 30% water changes on each tank and re-dosed the tanks for the water change amount. Tonight's testing revealed about the same levels. Ammonia is around .50 ppm, Nitrite is at least 2 ppm.

Thanks for the compliment on the tank! I will be covering the filter intake soon. As far as the frog goes, she/he is eager to eat ... I wish the others (dwarfs) had it's appetite (clawed frogs would stuff themselves if I let them ... did increase to 2 reptomin pellets each).
