Question Softened water High KH

With three tanks (the largest 75g planted) it is most convenient to use water straight out of the tap. Unfortunately we have a water softener. The kh tests consistently at 15gdh while the gh is low (I don't remember this parameter). I am new at the planted tank and wonder if this parameter is the reason for a nearly constant battle with BBA.

Thanks for your comments
75Gal
ph 6.8
15 nitrates
0 nitrites
2.65 watts per gal
pressurized CO2

Heavy fish load
2 3" Angels
5 Buenos Aires Tetras
6 small SAE
4 Black Tetras
2 5" Large Silver Dollars
3 bronze cory's
6 Tetras-(I forget the species-silver w/black tails and red around the eyes)

I dont think your water KH has to do with bba. If i was to guess, I would say that your CO2 levels are not high enough. You say your KH is 15? With KH that high and PH of 6.8 you are looking at 70+ppm of CO2. Somthing is not adding up here. Oh and what is your PO4 looking like? IF your co2 is in order, then it may be your dosing.....what are you doing for that.

I know, I know??

I was under the impression that softened water had some affect on the calculation of CO2 levels. My fish are happy and not gasping for breath.

I'm in Iowa. My water tests very high KH and low GH as well. You have my sympathy.

I wouldn't exclude the possibility that water with an unbalanced chemistry can cause all sorts of algae problems. Removing certain elements like it's been done with softener salts can't be beneficial for plants.

If you can bypass the water softener unit (via long garden hose) I'd suggest you try that.
