I'm running a 10g tank with a 2.6g sump. I am trying out the PPS Pro method of fertilizing and wondering if I should be dosing for my planted volume (10g) or if I should be dosing for total water volume (12g).
Maybe the extra 2g in the sump doesn't make that much difference? Now that I've written it down, it probably isn't that vital since every tank is so different that one program can't account for every tank. That being said, I'm fine with sub-optimal performance in the 80% range as long as I'm not fighting with algae.
Any one with experience?
