Hello everyone,

I'm a bit of an unconventional user in this forum. I'm a researcher, and I'm interested in studying the effects of high alkalinity on three different coral species and red crustose algae. I joined this group to learn more about dosing, alkalinity reactors, and your personal experiences in high-alkalinity environments. I recently purchased two Alkalinity DKH Colorimeters - Hanna Checker and the cTech T-2 Calcium Reactor to test. My goal is to increase alkalinity from 3000 to 5000 umol/kg (approximately 8 - 14 dKH). For our experiments, we need to use calcium oxide (CaO), Olivine (MgSiO4), and sodium hydroxide (NaOH) as alkalinity agents. Our tank's capacity is 450-500 L and it is a flow-thru system at 10L min-1 which gives a residence time of about 50 min. Any recommendations are welcome!

Add 283 grams of sodium hydroxide to 1 gallon of fresh water. It will get quite warm. Make sure it doesn't soften your container. This solution will contain about 1,900 meq/L of alkalinity (5,300 dKH).
