after calibrating the controler i programed the desirered ph to 6.7 thinks this is right (ph was 7.2 before i started )
i have a 300l tank so i put 30 bubles per minute in acording to the instructions the ph droped down to 6.7 and the shut off valve turned off the co2 .question when does the co2 come back on again ?the controller shows 6.69 now hasent moved for about an hour any advice apreciated thanks in advance
