Phosban reactor as C02 reactor?

[FrannyB]

Do you think there would be any structural limitations to this piece of equipment that would make it unsuitable as a C02 reactor?

Done.

How would you plan on injecting the CO2 into the chamber? You may have just as much luck injecting it straight into your canister filter's intake, or is that not working?

I see two potential and related problems.

This thing will inflict significant head losses on your plumbing. It has a couple of sharp elbows and forces the water to make a lot of turns.
Relatedly, I see that it is rated on the order of 30-40 gal/hour. That's a pretty low flowrate. I'm guessing that their figure is for phosphate removal (which is sort of entertaining to me seeing as I add phosphate every other day), but it also means that the whole thing just may not be well sized for a higher flow rate.

And by the way, if you want to make a PVC "rex-style" reactor...it is super easy. I'll even show you how at the potluck.

I agree there are much better methods for cheaper, RexGregg reactor, Cerges, or the best one ever CarbonDoser EXT5000, just ask me or Julie.

The reactor I use is clear and I use it as a bubble counter. However, the more I crank the C02 it causes less water in the reactor. I'm thinking that either I put a diffuser of some type in the line before the reactor or get the phosban reactor and fill it with sponges to break up the large bubbles to diffuse the C02. Thus eliminating the buildup of C02.

The outtake does not produce bubbles or anything. I'm just confounded about the current reactors inability to stay full of water ensuring that I'm not wasting C02.

Well that's why the Carbondoser works so well, it has 2 chambers seperated by a sponge and a pump that recycles the water in the chambers to get all the gas disolved. This is how it fixes the problem your having, your reactor is getting the water pushed out by the gas because it's not getting desolved into the water fast enough. So at a small bubble rate this would be fine but you have a lrger tank that requires a faster bubble rate and the reactor is not effecient enough to handle this larger load.

I know you love your tanks and playing with them more that anyone, so one day by yourself a nice present, the CarbonDoser EXT5000 and if it doesn't do what I've told you I will but it from you.

Another benefit of the effiecient design of the CarbonDoser is it does not require you to use up as much CO2.

What's up with the 90 degree bends. Won't that restrict flow?
