So I recently set up a 5.5 g tank which I'm trying to make high maintenance.
I didn't think I'd need filtration because I thought if I put enough CO2 into the water (via hagen co2 ladder) that simple diffusion would take placea and distribute it throughout the water. This is clearly not happening because although I have 40+ watts over the tank and two 1liters going, my plants are not pearling nor showing any significant growth.
Substrate is schultz enriched with laterite and plant mulm from another aquarium.
I'm dosing using GW ferts via estimative index.
lighting is 40+ watts over the tank using 2 screw in daylight bulbs. It's very bright.
Maybe it's the temperature?
I recently got outbid on a zoomed 501 canister filter. Can't do that anymore.
I've searched every local hardware and fish store. No small water pumps. I was going to make my own canister filter but that's not going to happen without a pump.
Wal-mart has the only non-HOB small filter that I was thinking of retrofitting to be a submersible reactor/filter. This is it:
Tetra Whisper 10I Internal Filter at Big Al's Online
You can see how it isn't truely submersible. My question is, do you think I could rig that up to be an effective way to distribute CO2 throughout a small tank?
If not. Any other ideas? Cuz I'm plum out.
