Water parms, what would you do?
I'm in the process of setting up a planted adult discus tank and just tested my well water PH, GH, and KH. After two days of aerating, circulating, bringing up to temperature, and tested with a new Tetra Laborette set:
Note - I have a water softener but this sample was straight well water.
Also noticed that the sides of the plastic rubbermaid trash can had a mineralized precipitation collection. Almost like a fine dust had collected on the sides underwater in two days. Now I remember why I had to use an RO/DI system before. I made a small batch of RO and it tested:
GH 0dh (looks like my RO filters and membrane are still good)
I wanted to use a mixed ratio of straight tap and RO/DI water but I've had problems in the past (diatom and algae blooms, unexplained deaths, etc.) with his water and had to resort to using only RO/DI and reconstitute it with RO Right, buffer, etc. This wasn't to bad when I was only doing water changes every 3-4 weeks with the previous setup. However I plan on doing weekly changes now for a planted discus tank. I've been reading a lot on Mr. Watsons bulk dry ferts and am going to go this route.
My question is what would you do? Experiment and try a mixed ratio or not take the chance and use only reconstituted RO water. As other sites and threads here have mentioned and made reference to, I don't want to "chase this dragon" either, but this tap water is terrible and I might be that 1%. I ask this being new to a planted tank and don't know if the plants would consume either the macro or micros which were causing my problems earlier. Or would a CO2 system lower the PH to a more acceptable level?
