Reducing Nitrates And Gh Without Ro.

[migdem]

Hi all,
I am thinking of using a small canister filter and will use resin and Seachem Matrix.

Resin to reduce GH and Seachem Matrix to reduce Nitrates. Right now the tap water has high GH and Nitrate of about 50. The canister will not be used in the aquarium but in a tank before I make the water change so this will be treated before.

What do you think?

I am aiming to host angelfish and in the future Discus. This water will be used for a tank which is planted and with CO2.

Any ideas from you? I do not wish to use the RO. I also cannot do any plants in this plastic tank because there will be no light at all.

The Matrix is a product that is used as a biological medium. It will do nothing to improve the water purity in a pre-treatment method. Simple ion exchange resin will do the trick in lowering your mineral content, including nitrates. The end result may well be water that needs to be mixed back in with tap water to get the desired mineral content.
I am curious why you want to avoid RO, since it is fairly cheap in use and can be installed into the kitchen sink for about the same cost as buying that canister filter.
