Chuck Gadd's C02 reactor Help!!

I recently built a c02 reactor from Chuck Gadd's plans Chucks c02 reactor My problem is, I dont see any increase whatsoever in c02 saturation. My ph and kh is the exact same everytime I test it. Did I build mine wrong? Has anyone else had an experience like this?

Thanks

how long has it been set up for? Your won't see results right away. Give it a good 3-4 days.

How many bubbles per minute is your DIY rig generating? How large is the tank? Is there a large bubble of CO2 inside the reactor?

3-4 days? how's that? When I inject CO2 into my tank I get the pH moving within the hour, sometimes less...

Kh should NOT change with Co2 injection...so lets be clear about that.

You shouldn't see the pH move much until you're going for a few hours. If you're seeing it move that fast Laith, you're shooting a hell of a lot of CO2 into the tank.

No, don't think I am.

I've got a KH of 4.5 and the CO2 system linked to a pH controller set to 6.8. When the pH gets up to 6.9, the solenoid opens and CO2 is injected (about 1 bubble per second). Within about an hour to an hour and a half, the pH is already reading 6.89 or 6.88.

It's not a huge drop in that time but the CO2 is definately already having an effect.

Well I guess it depends, I just assumed he was using DIY CO2, why i assumed that I dont know. So tell us MantisX are you using DIY or pressurized?

My pH is set for 7.0. When it rises to 7.1 the CO2 is injected at a rapid rate and within 15-20 minutes its back to 7.0. Should I adjust this process to inject at a slower rate (bubble count) or does it matter? ...it's the same amount of CO2, just injected at a faster rate, am I right?

Hi all. I am using DIY c02 bubbling at a bubble per second. The reactor has been setup for about 5 days with no changes in ph at all. Id also like to add that my tank has an open top. The tank is a 10 gallon. Im about to just give up on it and ebay the powerhead and just let it bubble into the water. Either that or try a hagen ladder.

Thanks

sounds like the reactor isn't doing anything to dissolve CO2.
the hagen ladder is great for tanks up to about 20 gallons if your doing DIY. it's actually about a 95% dissolve rate, and if you have a little flow in front of it, the CO2 rich water is getting distributed throughout the tank.

The ladder sounds like something id like to do, but the cheapest one I could find was 17.00 shipped. Does it really cost 7 dollars to ship this thing? I guess if I have to ill bite the bullet, because I really think my c02 levels are why my algae is getting out of control. I dont dose that much and the plants bubble, but I can tell they arent using everything I put into the water.

Thanks

Whoa! That is pricey.

You might want to put together a bigger order.

The problem is your ordering a single item and getting nailed for the base shipping rate, the frog is right, order a few more items.
