I have a 30 gal low tech jungle style tank. I recently read that increased (water) circulation was good (in general), so I installed a circulation pump to add to my canister filter circulation. I then first heard that surface agitation increase was also beneficial for oxygenation, so pointed the canister filter return more upwards to increase this. Adding Seachem Excel on a daily basis. As the plants steadily grew more, I increased the dosage. I THEN noticed that green hair algae started to appear and after further reading, I saw that apparently the increased surface agitation actually helped speed up co2 dissipation, so I should reduce this surface agitation while still increasing Excel dosage as the plants grew (obviously with a "lower" dosage after pruning). Lighting has been a constant 6 hours a day with an hour before and after to bring the power to 65% or at the end lowering same to zero. pH is a fairly steady 6, water temp about 25ºC.
In another thread here I read that surface agitation should be increased in low tech tanks.
Fair to say, I'm getting confused. Does anyone have any pointers?
