Low Alkalinity

[bromion]

I'm using Tropic Marin Reef-Pro, and I have found my alkalinity to be on the low side -- around 7 dKH. What do you recommend for raising the alkalinity?

You can use baking soda(NOT baking POWDER). Better yet is "baked" baking soda-350 degrees for 1 hour. This gets rid of any CO2, etc. that the B. soda may have absorbed. Here is a good Calculator to find how much you need(includes amounts for "commercial brand" additives also)-

I use Bionic 2 part additive made by ESV... Works great..

Bionic 2 part additive

I don't like using just one part to correct chemistry issues. B-Ionic has many more ingredients than just Alk and Ca booster. Each part contains numerous other components that can quickly "unbalance" the chemistry of your tank. Two part additives are best used when adding equal parts of both the Ca and Alk supplement to maintain parameters rather than fix one or another. That's coming from a recent personal experience...
