On something as large as a 50 you may as well invest in injected CO2. Consistent, long lasting, and more powerful than DIY.Lights are on 8 hours a day.
Tank has been running roughly 4 months. CO2 added this week. 4 hrs a day. It’s only DIY CO2 and it’s only consistent for about 4 hours then bubbles slow to nothing. That’s why I ask
I paid $25 for a year's worth of CO2 with a 5 pound canister. Many gas companies will do exchange programs where you rent a tank, then bring it back and swap it out for a full one as needed.I agree with Fahn entirely, as DIY's can get a bit labor intensive and kinda frustrating! Almost weekly maintenance...mostly, it can be a bit inconsistent--hence your only 4 hours of CO2! So one of my 10 gallon, mid-tech tanks, I actually bought a cheap Fluval 45 gram CO2 kit from Petco, and use cheap $3 bicycle CO2 cartridges. Every day the CO2's running about 6-7 hours, and each cartridge lasts about a week to a week and a half--thus, for only about $6 every 2 weeks. On another 20L tank, has a very large paintball CO2 canister as well. Although usually those require an adaptor, which you can pick up at Home Depot or Lowe's etc. The paintball CO2 tank is refillable for about $4.
Check locally and see if there is a gas supplier, beverage service (they supply CO2 for softdrink dispensers), or even a welding shop. Most will either do exchanges or refill an existing tank for dirt cheap.That's super cheap!!! Holy macaroni...
To put it into perspective, 5 pounds is approximately 2268 grams, equal to about 50 Fluval CO2 canisters. If one canister lasts a week that's almost a full year for a fraction of the cost.Yeah head to Home depot for an adaptor. WalMart may even have 'em too...MAY have 'em...I think I'm gonna get a bigger canister for my main 55 gal. now!!! Muchas gracias Fahn sir, heh
