SUcky Water

My tap water has a ph of 7.4, kh of 7.7, and 0 gh. What can I do to make the water better for plants?

40 gallon SeaClear Acrylic, 192 watt Orbit Lunar PC, Filstar XP2, Filstar XP1, JBJ Regulator, Rhinox 5000 glass co2 diffusor, 9 watt UV sterilizer, Hydor Inline Heater, Pool Filter Sand substrate
Filstar pimp #53

How comes shoppings so stupid, looks at all this stuff I haves, what do I do's with it.

I think you need to retest the water. A zero GH with a 7.7 KH doesn't seem likely. The reverse seems more likely.

And test the water after it has rested for about 24 hours. Water with a kH of 7.7 should have a ph of around 8.

Why do you think your water is not ok? Add some gH and you would be good to go.

A home water softener would yield those figures. My "soft" water has a KH of 18 and a GH of 3 - 4

My guess is that you have a home water softener that is stripping out all the calcium and magnesium from your water. If that's the case your water has elevated levels of sodium (assuming you use NaCl rather than KCl) which I have read some experts believe is not good for aquatic plants. What you should do is check your kitchen sink's cold water feed, as it may bypass the home softening unit.

A water softener! Of course. Sorry I didn't think of that. Not having one, nor ever having one, I never think of one.
