hehe..dun increase too much lor, recommended is 30ppm for planted tank

but since u dun have much plants, so i think u can increase a bit first, how is ur plant growth so far ?
sump tank is something like image below, for filtration

I'm using 2215 now. so dun need the sump tank. my Plant grow a bit slow, maybe... But last time I use 30bpm, BBA appear. Then put in flying fox and yamato, and increase CO2 to 60bpm. now controling.

Best if you could get a Eheim2217. 2215 is kinda too slow for 3feet aquarium.
Get some soil, so you could go for more kinds of plants.
55W is too low for 3feet, Aquazonic has T5HO for 3feet with 36W x 4 = 144W

CO2 bubblerate is depending on how pack is your plants. More plants need more CO2. Get a co2 indicator to check if you are overdose or underdose CO2
Hope this helps

Last time should have buy 2217 when got promotion

thought 2215 sufficient enough. maybe add on a cheaper canister.
weijie, how much is the 3ft Aquazonic T5HO light cost?
