I'm just researching setting up my first tank, looking at 90 gallon FOWLR
I have well water - we have a brand new filtration system + UV
+ softener, so the water quality is consistent. It has low pH though, and I'm not sure on the effect of the water softener.
From professional analysis of the tap water after going through the system:
pH = 6.54
hardness < 2 PPM
nitrate < 0.2 ppm
magnesium < 1 ppm
total dissolved solids 160 (v. low)
All the info I read shows most saltwater fish needing pH in the low 8 range, but also that as long as pH is consistent it's not that critical.
It also has very low hardness, but that's due to the water softener - not naturally soft.
So am I OK with this water for my tank, or am I going to have to do anything to water, or are there certain fish I need to avoid given this makeup of water.
