Our GLA manifold blocks make it easy to expand CO2 distribution to up to five aquariums. Each block contains our custom built-in needle valve and bubble counter to direct supply of CO2 to an additional aquarium, independently.

Additionally manifold

I recently just set up a new tank with a sump. I need another manifold block to my set up. I place an order. I got my order in 3 days. I also got the co2 reactor with it as well. Installation was very simple. Just remove the 2 Allen wrench screws. Add the new block in and use the new Allen wrench screws and that's it. Do not try to take out the Philip head screw. You will risk striping the head, it is on very tight. Also there is no point in removing the Philip head screw.

Awesome thingy. It works great. No more need for a separate bubble counter or check valve. Very happy with this product. Easy to install.
