how can i get the drop checker to change to lime green when the lights go on in the morning,the dc is only changing about 2 or 3 hour in to the lighting period,and then it is changing to lime green so im getting the right amount of co2 in the tank, just not quick enough,i have a 260l tank,and using a reactor from china that is meant for 200l to 300l tanks,the lights are on for 7 hours a day the co2 comes on about 2 hours before lights come on ,and go,s out,2 hours before they go off,im getting pearling on the tops of the plants for about the last 4 hours of the lighting period,but nothing on the lower bottom plants ,i have read some posts and they have said to cut the amount of dc solution down,so i have done that, but its still the same .....

Peraphs try putting the CO2 on 3hrs before the lights? Does anything else change when the lights come on? Or have you got high surface agitation?

Have you checked the solution in the DC? It should be blue when you first add the pH reagent then turn green after a few hours int eh tank. I assume you are using the 4dKH water and not tank water?

Hi Lee

I'm going through exactly the same thing, but am adjusting the bubble rate, and the time the CO2 switches on to try to get the DC green when the lights come on, but not to get too yellow as the day goes on. I'm switching the CO2 on 15mins earlier each day and seeing when it gets to grass green.

My setup changes 20% of the water (60l) every morning before the CO2 switches on, so that also removes the CO2 from the day before.

Hi,
Don't blame the Chinese. :lol: Slowly add more CO2 while being careful not to gas the fish. Your injection rate and/or your flow is sub-par.

Cheers,
