Another RO thread but I did read the others first!
Hello, sorry if I missed something when reading other threads before asking my questions.
Most the other threads are normally a person wanting a RO for one tank and or one species of fish maybe.
I'm wanting RO for soft and hard water fish breeding.
Fish I want to breed range from 5.8 to 8.2 or so in ph.
Current tap water is about 156 TDS and ph about 8.3
I see mixing RO with tap water as option, but recently I lost a whole tank of fish who were doing fine for 6 weeks in a quarantine tank with out issue than started to drop off like flies with heavy breathing and nothing else. The aquarium had been running for almost a year and housed a some glofish for few months for my kids and than a small pleco before he got put in a bigger aquarium. I tested the hell out of the water for TDS, PH, ammonia, nitrates and nitrites. Other aquariums are fine but they are super heavy planted aquariums why this one had no plants. I'm thinking a heavy metal is strong in the tap that prime isn't able to deal with and killed them.
Looking at RO water there is a TON of chemcials for mixing to get a GH and KH to good spot so there isn't crazy PH shifting and checmicals for ph and so on.
Was looking at - Equilibrium, Discus Buffer, Alkaline Buffer, Acid Buffer, Discus Trace, Trace, Neutral Regulator but this stuff looks like it will get pricey in the long run of water changes. Wanting to mix this stuff up in brute trash cans and heat/bubble 24-48 test than add to tanks for water changes.
Also saw thread where some mention using Ca MA and P dry ferts to re-mineral water and said it was cheap. My problem with that is looking at them looks about the same price and no idea what is fish safe.
So over all my questions are would tap water be my best bet for planted aquariums with breeding projects? Tap water is suppose to be clean and very good in the nation and won awards but this recent loss makes me question it.
If I were to skip the Ro and Tap mixing, what would be a safe affordable route for getting GH/k and ph right for planted aquariums with chemicals?
Thanks in advance on any help into this matter.
