I've been using my newly built cerges reactor for a few weeks now and I'm still wondering:
A) Why is my drop checker only reaching green/blue when I'm running a lot of bubbles per second? It's pretty much a constant stream of bubbles.
B) Why does it take so many more BPS than a normal diffuser or Rex Grigg reactor even?
I realize that with a diffuser the bubbles are filling the water column and getting into the bell causing the drop checker to get a higher reading faster. And that a drop checker is only a very rough estimate of CO2 levels, but it's all I got. What is the better situation for growth, a yellow/green drop checker with 3 BPS from a diffuser or a blue/green drop checker with 7-8 BPS from a cerges reactor?
I really like the cerges reactor because of the no bubble look and having less equipment in the tank, but I'm starting to wonder if I am using the best method.
Unless you have a leak somewhere, the Cerges is more efficient. Especially if you do not see any micro bubbles out of you outflow pipe. If you don't see micro bubbles you are getting 100 percent dissolution of CO2.
You're drop checker was probably giving you false readings with your old diffuser pushing CO2 into bubbles into it.
Double check for leaks, Then watch your plants for increased growth.
Tank size,type filter used and what size house filter did you set-up ? I use a 20" x 4.5" house filter with a Eheim 2262 filter for my 110g tank and it works great . I fill my reactor with mini bio balls to break up co2 and the flow and I get 100% diffusion.
I've tried tilting the reactor and there's no change. I don't hear any gurgling from it like if there was a gas pocket.
I'm not getting any micro bubbles from the output. I sprayed soapy water on all the connections...no leaks.
It's a 40 breeder, Aquatop 500 filter, I used the normal normal size filter housing not the 20" and I put a coarse sponge in the bottom. Like I said no bubbles escaping the reactor.
This is really frustrating be cause the bubble counter is pretty much a constant stream of bubbles and I've put new 4dkh in the checker and still getting the same reading. Unfortunately I can't judge anything by plant growth as of right now as this is a new setup.
I'll have to check my ph. Haven't done it in a while. It used to be that in the morning it would be at 6.8-6.9 and during the course of the day drop to about 6.4-6.5. I have quite a bit of flow but its not breaking the surface. A rolling boil is how I'd describe it.
My reg is still set to 30 psi. I never reduced it from when I had the diffuser on. Bad on my part. I'll have to lower it later.
The filter is the canister version of the aquatop. CF500 I think it is.
