Hi all, I've tried for ages now to get the CO2 levels perfect in my tanks. Over the months I have attempted to get a 1 point drop within the 2 hour mark, which seems to be normal for most.
Sadly to achieve this I'm pumping in large amounts of CO2 into the tank, which in turn has resulted in stress to my fish. Eventually I realised that pumping large amounts achieved the 1 point drop, but it just kept going, which led to a drop way beyond 6.8.
So I backed off the injection rate until I achieved the one point drop, then adjusted the timer. Unfortunately this has meant that injection starts 4 hours before lights on! Is something wrong?
Tank 1
200 Litres
Sera Co2 reactor
My resting PH is 7.8
KH 6
Target PH 6.8
4 hours before lights on.
2 x external filters APS 1400 and Ehiem 2217
Wave maker
Tank 2
90 Litres
Inline diffuser
My resting PH is 7.8
KH 6
Target PH 6.8
4 hours before lights on.
APS 1000
Tunze 6010
Both tanks seems to drop at the same rate.
Plants have suffered over this period due to the erratic CO2 fluctuation during testing. I have reduced the lighting in both tanks to try and reduce the stress on the plants. EI dosing as normal.
Everything checked for leaks.
GDA a problem in tank 2
Tank 1 has a yellow/green dusting, which is possibly GDA, also small outbreak of BBA.
Both tanks have a large amount of flow.
Is 4 hours way to early? If so what am I doing wrong?
Thanks
