Aquarium Advice Addict
I recently bought this thinking that smaller would be better for trying to get it inline with my canister, but it ended up being backwards, and that bigger is better for low pressure systems. If you have a sump with a return pump that can give you 5psi+, this injector will work well for you. My setup only has 2 psi..ish and when I tried putting it inline with my canister, flow came to a trickle, and I had to disassemble it. You can adjust the amount that the co2 is dissolved by using a bypass, which has been well developed by Tom Barr and alot of people at plantedtank.com. Tom spent alot of time using this, and decided that undissolved co2 being absorbed directly through the leaves is more effective than dissolving co2 into the water. One thing to make note of is that pH swings are much more prevalent in this system than others (I can't explain it in the really sciency way, but that's what the links are for )
I can guarentee that this injector is in the same condition that I bought it in (aside from the 1 gallon of water I pumped through it). I'll try to help out as best I can, but I'm not very good at the whole math pressure head height flow equation math stuff. I have found that the engineers at Mazzei are extremely helpful, and they are very dedicated to helping us, even is co2 injection isn't they're normal use.
Right now, I want $25 shipped for it, but maybe it will go down if there isn't any interest
