oh another question I have for users of RO water

[Silverfish]

I am pretty bad about testing anything! [img]images/smiles/icon_biggrin.gif[/img]
Can't even remember the last time I tested for nitrates or the other two... (at least 6 months)...I should really give this new Salifert alk/kh tester a try one of these days...got it at J&L last month [img]images/smiles/icon_wink.gif[/img]
I do like the Salifert calcium tester tho.. very easy and accurate
