Plant tank filters
Here is my $.02 worth....
I started my first planted tank just less than a year ago. I have
succeeded wildly with lots of different swords and frogbit, ok with
Anubias and Cabomba and Aponogetons and Microsoria, fair to poorly
with Crypts and death to Lilleopsis(sp?) (several portions). I now
remove about 1/2 pound a week of plant material from my single 50
gallon tank. I leave it to you to label this successful or not.
I use hand injected CO2 with a ugf with a 50 gph power head. I think
it is much too much flow, but it is what I use now. I go on a
water-changing binge every 6-12 weeks, where I change 40% every day
for a week. Then everything spawns (there are a LOT of fish in this
When (not if) I redo this tank in July or so, I will lay down 3
pounds or so of laterite, cover with small pebbles, drift on 5 pounds
green sand, cover with 2 inches of #3 aquarium gravel, put in a
custom split ugf with heater in one riser and airstone in the other,
and then 1-2" more gravel. This is intended to be anaerobic on the
bottom (thanks dr dave) and aerobic (biological filtration) on the
top. Best of all worlds (I hope).
