co2 system enough for my large tank?

i got 265gal tank. looking into co2 system now that everyone says i need it...

"its 5lbs full CO2 canister, regulator, bubble counter, drop checker, tubing and a diffuser.

Both the regulator and electronic bubble counter are from aquarium plants.com
http://www.aquariumplants.com/Carbon...ator_p/co2.htm its $249.99 one.

The tank is from Airgas and it is aluminum. The diffuser is from Fluval."

i may upgrade to 20lb tank, but is this enough for my size tank???

You might want a bigger bottle so you're not having to go for a refill so often. I have a 5lb on my 75 gallon and it lasts me two and a half to three months. If the Fluval diffuser is the one I've seen then I'm thinking it might be a bit small for that large of a tank. If I were doing that size tank, even if it were low light, and I wanted to do CO2 I would look at a needle wheel pump, DIY reactor, inline diffuser or using a couple of larger diffusers in the tank.

Some people like the regulator you've listed and others haven't reviewed it as well. You might also want to look at some of the regs for sale on the forum, link below. OldPunk also builds regs and you could always send him a pm.

I agree with Jeff. I have a 180 g. I started with 5lb and it lasted just a little less than a month. For just a few more bucks they let me trade the 5lb in for a 20lb which last 3 to 4 months. Another thing is they charge 24 dollars to fill 5lb and 28 dollars to fill 20 lb.

What has it been a week and you're already wanting pressurized CO2? I think you may have idiopathicmacrophytic addiction (IMA) .

Why not ask bettatail or oldpunk78 for advise on your CO2 setup. They seem to be the "go to people" here. The one you listed, although cool, would be more prone to problems. Old school mechanical seems far less likely to give you problems IMO.

Make a reactor or two, don't use diffusers. Either a big Cerge's 20" with at least 1" outlets and a 20" whole house water filter or like this one but way bigger - 24" by 2-4" at least with inlet/outlet of at least 1".
https://www.plantedtank.net/forums/sh...ad.php?t=65191

Your pump has power to handle a couple of reactors and have a good amount of flow, right? You might even have a couple reactors and one or two returns. Might work better. The 20" Cerge's with only 3/4" outlet/inlet is fine with the Rio 2500, might not be okay with more flow than that.

Well that's an incredible deal. I would go for it as well. I thought you were paying list price for everything. Good for you!

If you are running a huge tank with a sump lots of CO2 needs to be introduced and diffusers cannot process as many bubbles per second as a large reactor. I cannot quite count how many go into my 180 gallon tank, more than 10 per second anyway. With your big pump any CO2 in there ought to move around the tank very nicely though!
