My ALK has been low for quite some time (dropping at times to 5.5 dKH) and I never really knew why. To be honest I didn't really worry about it much since my pH was ok and I don't have any coral, it's FOWLR right now.
I decided I would address the issue and added Randy's diy alk solution of baked baking soda to raise the ALK. It took 60ml total to raise it 1dKH to 7. It has since then dropped .8 over three days. The only thing I can think of that's doing that is the small amount of what appears to be Coraline algae in the tank. It hasn't spread much in the last few months but I'm assuming that's because of the low ALK.
By my figures it looks like I'll need to dose 15 ml daily to keep the ALK up, tank is about 80gal total volume. Does this seem about right/make sense?
