I've got a 2213 below my 29-gallon tank the I beleive the filtration (and lots of it) was the final piece to the puzzle that got my tank right for plants. Maybe I should have gotten a bigger pump.
1.9 average watts/gallon (55W, CRI 91 @ 5000K, polished Al reflector).
Two to three inches of fine natural gravel.
Snails - tank only supports a few.
pH - somewhere between 7.4 and 6.8 depending on things.
High pressure CO2 with a Azoo diffuser - manual solenoid.
Filtration - 2213 with standard packing (including the charcoal filter).
kh - 3, thanks to a baseball size chunk of cool looking limestone.
nitrate - Can't read anything so it's probably 10 or less.
ammonia - 1 mg/l in my tap water.
phosphate - don't know and don't care.
Fe, K, Mg, etc. - most likely.
Ferts - aquatic substrate monthly, occasional liquid macro, daily fish food.
Fish - 5 lemon tetras, 6 pristella tetras, 2 cats and 6 very hungry ottos.
Algae - hard to see any. My ottos eat fish food, too.
Plants - Bushy red ones and green ones make it hard to see the fish.
