Fish Crazy
I have a 200ltre tank and started dosing Co2 about 6 weeks ago, I regulated the bubble checker to 50 per minute and the drop checker turned from blue to green, great I thought but then I noticed the leaves at the bottom of the plants were brownish whilst the upper were nice and green.
My set up consists of a diffuser with a Hydor Koralia Evolution Circulation Pump directly above it at the water surface.
So I had this idea of lowering the circulation pump so that it was just above the diffuser at the bottom of the tank.Within a day the fish were at the surface inc the plecs I looked at the drop checker it was still green.
My first reaction was to reduce the Co2 down to 20 per minute but then I realised that I had removed the aggitation away from the water surface which is what I believe caused the Co2 to spike. I know drop checkers can take a few hours to react but even at 20 bubbles per minute it remains green.
How is it possible to get Co2 to the plants at substrate level like HC Cuba?
I would be grateful for any comments as I beginning to think that Co2 is a waste of money.
