isellcars Tiny bubbles I can live with but they are pretty big. You can see them go into tank then straight to the surface. Not even getting near the plants, so no benefit at all.

Kathyy My Rio 2500 is probably pushing about 500gph with all the head pressure and that is a bit too much for the 20" Cerges I am using so I get a few tiny bubbles. I would split the return and join it after the reactor. Thinking you want as much flow through the reactor as possible so a ball or gate valve on the new line that you close until you start getting bubbles then back off a little so more water goes through the new line. I think that is how I would do it if those bubbles bothered me.

I have my new reactor built and its up and running. The reactor stands about 20". I still have huge co2 bubbles coming out the return. Could this be that I am pushing too much water through it to fast. My return pump is rated at 900 gph....if I slowed it down would this make a difference? Or I thought about putting a Y clamp and have one side go to the reactor and the other just go straight to return. Of course I would have to have another Y clamp on other side of reactor to join it back up to go into a single return. Any thoughts?

HD Blazingwolf that is one reason why it takes more effort to get ur DC to turn green!!!!
unless ur sump as no surface movement

stevenjohn21 How do i feel like im Hi Jacking the thread when its mine originally ! Glad to see you are getting your problem sorted LOL

isellcars Not at all. It would be to difficult to seal it with everything in it.

HD Blazingwolf do u seal the sump at all?

isellcars I don't want any equipment in my tank. That is why I bought a tank that has a sump tank as well. Plus my pump pushes about 900 gph and I figured that with the reactor it might be down to 800. So there really is still great water flow in the tank with the reactor.

if you don't mind all the bubbles in your tank why not just use a diffuser? no reduction in flow associated with the reactor's plumbing to worry about, less chance for leaks, etc.

isellcars I have reversed the flow in the reactor. Now it's just a waiting game.

HD Blazingwolf I was assuming the return IN the tank is at the bottom. in which case if bubbles are escaping. they are going to rise to the surface. the further up they have to go. the more time they have to dissolve Vs the return being at the top of the tank
