Byron, is there a formula for how many plants to add for this method?
I ask because, even though I had plants in my 55g and seeded it, I did have a small nitrite spike (5ppm) a few days in. I never saw any ammonia. At the time, I had 9 Vallisneria americana, 1 Vallisneria spiralis, and about a 6"x12" patch of Pistia stratiotes. I added 7 Bloodfin tetras, about 1/2" to 1" each. It wasn't a problem, just two water changes and I was seeing nitrates in 5 days. The nitrates have always at or under 5 ppm. Easy peasy.
BUT... Since I'm starting up another tank soonish, I wanted to know how I could avoid any spike at all, which would be better for me and better for the fishies. I understand that the type of plant is a factor, but any advice for (me and) the original poster about how many plants per gallon/per fish?
