Ways to distribute the CO2 in the tank

[dwgi32]

Hi,

Care to share your method of distributing the CO2 effectively in the water i.e. using CO2 reactor, using power head, using inline diffuser attached to the otulet of the filter.

Nano diffusor under the OHF. I have minimum surface agitation by the way. A small powerhead located adjacent to the OHF circulates the co2 enriched waters.

Assume that i need a powerhead to improved the circulation in my 3 ft tank.

What's the flowrate of your filter? If it's strong enough and the outlet is place at the correct position, should be good enough.

250gph for a 3ft by 1.5ft by 1.5ft. However, as i am using a rainbar and the CO2 diffuser is at one corner of the tank, hence i assume that it is not well distributed.

Hm...flow rate, ok, With rain bar may soften your circulation a bit. Why not try without it. I use to do so (no rain bar) with only 440l/hr with diffuser on 3ft tank and it was fine.All plants were bubbling. However, since I've upgraded the flow rate to 1200l/hr and using reactor...sad to say, no bubbles already even though the plants are growing...., i wonder why...
