Adding Calc and Alkalinity buffers

[harryb18]

I have a 90 gallon reef tank and find that in order to keep my akalinity between 10 dkh ande 11 I need to add approximately 100ml of little fishes liquid alkalinity component daily, I also add approximately 50 ml of little fishes calcium additive daily in order to keep my calcium readings at approx 420-440. For some reason I feel that I am adding too much of the liquid additives to keep my tank in balance can anyone provide any insight into this matter?

Thanks

HI Harry

what typr of coral do you have in your tank ? If you have sps (lots) it will suck up lots of alk and cal . I add about 100ml of randys 2 part to keep my 90 are point ,If youre usng phosban or rowaphos that will affect alk too

I have a combination of sps and lps in addition I also have a phosban reactor on the sump. I guess I should not be too concerned as to the amount of additives. Thanks for your rapid response.

harry, what size is ur tank and which test kits are you using? make sure the test kits are not off.
also note that magnesium can play a role in ca/alk stability as well.

I have a 90 gal tank and am using sailfert alkalinity and calcium test kits.
I do not have a test kit for magnesium and have not measured it in my tank.
