So yes I know everyone is telling me to use kalk :) but until I figure out all the logistics of doing that I have this question.

I'm using IO salt and ro/di water. We usually change out 15g every other week. Have found out that my fresh IO salt water only gives me 300-350 Ca level. I usually make the water, add salt & then let it sit with a heater and power head to circulate for 2 days in a rubbermaid bucket before doing the wc.

I've finally gotten the tank to a Ca level of 400-450 by slowly adding Kent liquid Calcium. And then two part to maintain. I'm thinking though that as soon as I do the wc the Ca level will plummet. Is that just par for course? Or should i possiblly treat the wc water to head this off?

Thanks for your input and my apologies if I'm missing something here.

Hey minyee...besides your Ca levels, your Alk levels need to be monitored as well. They have a very dependent and needs a balance relationship. Try searching for some threads here and/or on google. Also, I would suggest gettings accurate tests for both. FWIW, I add a cap of Reef Complete to my weekly make-up water and this seems to be keeping things balance.

You can bring the Ca level in the new water to match the tank water, I do that when I do large water changes(20%) by using Dow Flake. Watch your Alk and Mg levels like everyone else suggested, these will screw up your Ca level too.
