Ive had my Rex style reactor on my XP-3 now for 2 days and although i dont see a mist of C02 bubbles i dont see it working very well. Today i decided to experiment and turned the needle valve open allowing about 20bps ! and my drop checker only turns to a light green. Fish are still very much active.
Does someone have a picture of there setup so i can see what tubes run where ?
the tank is a 75 gallon standard, no airstone just Rena XP-3. C02 seems to be dissolving as ive sat and watched the output for about 20 mins and dont see any bubbles (maybe every now and again)
I turned the reactor and shook it so there shouldnt be an airpocket.
The outflow from your canister should go to the top of the reactor. The bottom of the reactor goes to the fish tank.
Thats how i have it setup but the reactor is not standing straight up. Its at an angle like 10 O'clock with the c02 entering the top. Do you think that with it not being straight up its causing a problem ?
When my reactor was hooked up it did just fine. I dont use airline tubeing as the silicone tends to bleed co2. I use a co2 specific tubing. It is around $4 a foot but worth every penny. You should be able to get it from big als.
a 75gallon is a lot of water to saturate with co2 and ur bubble size can contribute a lot to misconceptions. if i had a bubble counter with that super small opening id probably be running 20 bps in my 29 gallon
as it stands with an open airline im at about 3-5 bps.. its hard to tell but they do come out fast
I used a reactor for years and they're all about flow. A reactor of this sort really cuts down on the flow from a canister. If I neglected filter maintenance I invariably paid the price with stunted growth (check out my journal and you can find a few pics showing this).
I think the issue is flow in the tank. I don't think a lone XP3 is going to cut it, especially with a big PVC reactor, as the only source of water movement in a 75 gallon tank that has or will have a lot of plant mass. You're going to need a filter that moves more water, a second filter or a circulation pump or two such as a koralia.
If your dropchecker is on the opposite end of the tank from the filter output try moving it closer and see if there's any difference.
I also have a Rex style reactor on my return from my sump tank. Except I have the return going in the bottom and out of the top to the tank. I am pushing about 800gph and I do see the fine co2 bubbles going into the tank.
My thing is no matter how much co2 I push in my drop checker stays blue. I do have it set up on the opposite side of the tank. Is this a good idea or not? Not sure if it makes a difference but I do have lots of co2 bubbles all over the drop checker.
