I've just invested in a 3 stage RO unit that should arrive sometime this week.

I've been doing some research and I'm aware that I need to aerate the RO water, adjust it's pH and add in some trace minerals, prior to adding it to the tank.

Most of the pH adjusters I've used in the past contain high levels of free phosphate which have caused my tank algae problems.

Is there a single product out there that will raise and stabilise pH to around 6 - 6.5, add trace minerals and doesn't contain phosphates?

I usually mix the RO water with 25% tap and add a little trace (under dosage). Which trace are you talking about that contain phosphate? I have Kent RO right, Seachem Discus Trace and Equilibrium and I think none of them contain PO4.

It was recommended to me by a very good lfs to fortify RO water with Marc Weiss "RO-Vital". Marc Weiss is world renown for his biology work with discus. Here are a few links i could find.

A large local lfs did tell me that it was too expensive for them to use the additives, so now they mix in a small percentage of tap water.

I add tap water to my RO with no problems.

My tap water contains approx 5 mg/l phosphate so no way will I buffer the RO water with that.

Going to try Seachem's Equilibrium to start with I think (can't find anything else in my local shops).

Thanks for the replies...

I mix in Kent RO Right if I need to increase GH. I'll bet that it's the same stuff as Seachem Equilibrium. K, Mg, Na salts. The usual stuff. All mixed together and overpriced .
