Circulation

[DavidW]

Hi

I've got a 3000 lph return pump which feeds back to the rear centre of my corner tank, If I add a T to the end of the pipe so the water flows left and right would I also need a circulation pump to ensure good CO2 dispersal in the tank? My tanks is a Trigon 350.

Thanks

Bit tricky to say really because of the shape and size of your tank.
I have found that basically fireing the flow towards the front glass so it hits the glass and travels downward and back across the substate towards the back of the tank works best. But hard to get your head round at first but it really does work. My carpet plants in the front of my tank have never pearled as much or looked better as they do using this method.
In your case using one outlet pointing twards to front glass at high level to hit the front glass and create that flow pattern or using two outlets would be better it is hard to say. Because there is a good distance to go before the flow hits the front glass. You would prob have to try it.
But i think that flow pattern would prob be the best for you.
