So, I make a solution of sugar and yeast (easy enough as my husband bakes bread all the time ;o). Save some money! I do actually have a second "unit" to put in since I have these on a 55 long and they are "rated" for 40g
My plants are doing beautifully! I wish I had taken "before" pix. Everything is growing well. My fish (2 Pearl Gourami) are REALLY skittish, though. They hide at the top near one of the heaters all the time. The male REALLY tries to jump out of the tank if I come near, even at feeding time. Maybe I should add a couple of other fish. I recently took 2 Angels out as they were spawning (into a 37). The Gourami are the only fish in the 55g. They have lots of snail company. Hitch hikers on the plants, I presume. Will have to address the snails soon. Some pond, some Ram's Horns.
I read another post that said fish probs may be due to over ferting. I have been adding Kent 2x weekly. Maybe I should cut back to 1x weekly for a bit and see if the fish do better. And, yes, I do weekly water changes, 50% +/-.
