40b with a 15"x9.45" 30ppi corner filter, pump with clear hose to spray bar. $32 for the custom Poret and two glass braces that were siliconed in place.
20L with two 45ppi corner kits that included lifters. I'd need to ask Bpophoto how much his kits cost.
Tanks cycled fine, no extra filtration necessary. The 40 has 6 ember tetras, 4 celestial pearl danio, 2 dojo loaches, 3 emerald cories, 1 black kuhli loach, 7 dwarf shrimp, 4 mystery snails and a nice colony of Malaysian trumpet snails.
The 20 has 15 endlers (some fry), 4 dwarf shrimp and 2 assassin snails.
The force isn't enough to stick anything but floating plants to the foam. The 45ppi is recommended for fry, the pores are too small for shrimp or fish to get stuck in. As I said before, the 20 in the bedroom is silent. Not so much on the 40 with the spray bar at current water level. If I take the water level up to the spray bar, that goes silent as well.
