$100 would have got you the CO2 scrubber + a bottle and a halfish of the absorbing beads.I am not sure. Just picked one with good ratings off of amazon. Mine was like a $100.00
I would much rather have ph at 8 and stable than ph at 8.2 then 7.9...
FWIW, there was a scientific study that showed that being at a higher pH for at least part of a day results in faster hard coral growth than one where the pH is stable, with a similar average pH.
I think it likely that growth will increase if you boost pH, and also probably if you increase alkalinity. Not sure which is the easier course, or if either is going to make a huge difference.
Do you have an ATO? Limewater in the ATO is often fairly easy.
I am drawing air from outside but still didn't get a raise in Ph. I am confused why that is? I know the room had high C02.
The reading is correct. Calibrated Ph probe recently with Apex. It is a 700 gallon tank 10 feet long with a 7 ft long sump. Do you have any suggestions? I would of expected some increase in PH? The tank has a 9.0 Alk reading that I keep pretty stable. I use a large calcium reactor that is set to run 6.5-6.7 Ph.Maybe a pH measurement error, or maybe more aeration through the tank top and other exposures to room air than through the skimmer.
No it is not practical for a tank my size. The fuge would have to be way bigger than what i have room for.Do you have a fuge? If you light the fuge at night you might be able to curb the drops and get a more consistency
