wow i just found this tread and started reading it from the beginning. WOW! only on page 4. It is super excellent. I just have horworts, some local grasses, duck weed, water cabage, local moss and cobomo plants. I don't have filtration and do little or no water changes. I have ghost shrimps three types of snails and a large number of insecs in my 10 gal tank. I will have to try the soap dish with suction cups and have out of water plants. thanks for this fantastic thread.
