Using RO for Shrimp

[Mark Webb]

If I were to use RO for shrimp is it fair to say that if I just add Calcium and Magnesium to adjust GH this would provide correct water quality?
I know that some add a percentage of straight tap water but I would rather avoid that so as not to re introduce any impurities that I have filtered out.

I think it would provide some level of water hardness (KH & GH) so ought to be OK. Personally I'd just use something like Tropica ReMineral (regular or discus would be fine)

What readings should I aim for when the ro is remineralised to ensure optimum quality?
