My Tank Thread
I couldn’t keep up with alk demand. I tried mixing sodium carbonate and bi carbonate to the point of saturation (even heating rodi water on the stove), but it wasn’t enough to realize any savings versus the Seachem product because I had to dose a lot of it (I get wholesale pricing). Trying another product while my tank was swinging in alk didn’t work out well. My sps tanks draw about 1.5-2 dkh of alk a day. Basically a lot of coral in smaller tanks. (50 and 75 gallon). Limewater is not an option I am willing to explore either. I’m wondering if caustic soda might be a better choice as an alternative.
The only way I can see a fail is if you just didn’t dose enough, or if there was runaway precipitation which requires steps to stop it before dosing more.
