Hi all,

I am researching into adding a CO2 system for my tank 72" x 24" x 30" 225 gal (nominal 180 to 200 gal tank). I have learned the definite advantages of such a system in a planted tank. I take it the bigger the CO2 cylinder the better (20lbs or better). Currently, I add 90 ml of Seachem Flourish Excel as a source of carbon on weekly water change, and 20 ml every other day. I also add Discus trace as I change water with r/o water.

I am running three eheim filters. Two filters are thermal units, and one filter has a surface extractor and a UV sterilizer attached to it. All three outlet (spraybars) are set below the water surface and aimed at an angle so not to agitate the surface. Can the diffuser be hooked up to the spray bar/s to deliver the dissolved CO2 more effectively or would it have the reverse affect? Also would the surface extractor remove more of the CO2? (I just don't like the surface film [protein??] buildup.

How much does it cost to fill a 5lb, 10 lb, or 20 lb cylinder?

What system do you suggest?

Thanks in advance!

Very good suggestions. Bryce, you mention you have a similar size tank with a cylinder, then you mention a DIY system. Did you switch or you have another tank setup? Also you said most people tap into the inlet vs. the outlet, is that to get the CO2 more time to dissolve in the water prior to injecting into the tank?

Glad to hear it! After making so many changes and mistakes along the way in my 5 years of saltwater, I'm trying to plan for everything before I fill up my soon-to-be planted tank, and do it right the first time.../
It seems when we have "perfected" our thoughts we would see something better and we would attempt to try again. LOL.

I see some of you mentioned to tap into either the intake or outtake of the filter lines. Has someone actually done this? Does it actually reduce the flow? If it doesn't anyone could tell me where I can get a "T" to attach to the intake lines of the canister filter and use the filter as the reactor? I was at the LFS today and set my eyes on some equipment. I just want to ensure I can get all the parts before I go and get it. BTW, I have three Eheim canister filters and thinking I'll tap into all three intake lines and get the best distribution of CO2 into the tank.

Any thoughts?
