Running 2 Diffusers from Pressurized Co2 - Equipment

Hi Everyone,

Just wondering. I have an 86 gallon tank and am getting my pressurized co2 unit next month. I was thinking that I would like to use two "ladders" or other diffusers (one in each opposite corner) in the tank. My question is:

Do I NEED to use a manifold or can I just use a "t" connector and have the gas split between the two (or more) diffusers?

Thanks,

KLT

You MIGHT be able to get by with a T. But the "path of least resistance" will most likely make it impossible.

Your best bet is to build or buy a CO2 regulator with a manifold a dual needle valves. That way you know you will have no problems.

Y join + "least resistant path" method works for me. Both planted tanks are bubbling. But if you are looking for long term hassle-free + leak proof setup, Rex has the solution.

I think ladder diffuser does not work well in large tank even if you have many of them. A CO2 reactor would be the best way to reduce CO2 waste.

Inline reactor, keep as much stuff out of the tank as possible....DC

You can use a 'T' type connector, but the needle valves must come after the 'T' and bubble counters after the needle valves will also be helpful.

Thanks,

We suspected that it might go via the route of least resistance but considering they are to be used in the same tank, we are looking for a cheaper alternative to a manifold.

We didn't want to put an in-line reactor since we don't want problems with the filters/impellers.

We thought of using a multiple line valve thing (the one with the knobs you adjust) but figure that there would be too much leakage going that way.

We probably will not use the ladders but even if we used two small reactors, the problem would remain the same. We just want more even coverage in the tank with CO2 - cheaply.

Thank you for your inputs, it's appreciated.

If you are looking For something with individual needle valves check out the jbj ones.

They are not required nor a necessity . It does make easiy regulation of bubble per second though
