My top off water alk is 3 and ph is around 7. I was just curious if people bring the ro/di number up closer to the tanks numbers or just leave them be.
As far as the PH that seems right for FW. You`ll get the desired 8.2 - 8.4 when you mix in the salt mix for PWC`s. What is your alk and PH on freshly made SW and your tank water. Just wondering
I was referring to the RO/DI top off water that goes in the tank to replace evaporated water. Do you typically bring the PH or ALK up on that? My tank water has a PH of 8.0 - 8.3
I was just thinking maybe it would be more stable if my top off water had a higher PH and ALK.
If you buffer your top off water, it's like dosing alk into your tank. When water evaporates, I don't think the sodium carbonate evaporates with it. I would think buffering top off water can easily throw your alk/ca balance out of whack.
Roka, what do you dose with? Are you dosing to raise or lower?
I hate to high jack the thread here, but I have noticed that my Ph has been slowly creeping lower and lower. Last night it was 7.9! I have been researching and there is lots of info about why Ph goes up, but not why it drops. I have been blaming it on some macro algae I got last month. Can anyone suggest reading on how to raise ph and what causes it to go low? I have been adding more an more coral too. Could that be it?
More surface ripple will help to raise the pH. I don't dose my tank with anything, just pre mix my water and use a ph to get the correct pH as my tank.
Roka, Oh, I misunderstood you. Thanks for clarifying, I do that too. I thought that the increased surface ripple decreased your Ph?
cccapt, Thanks for the article that is exactly what I was looking for. I will read it this evening.
