Here is my water report, please if you are knowledgeable in this, review it and help me out. I have never struggled keeping fish before and would like to solve this problem. I'm stubborn and the more things don't work the more I want to fix it. My electric blue rams just don't seem to make it. I have had success with only one, which just passed after a water change. I don't know what is going on.
here is a link to what I believe is the most recent water test available for my area:
these are my tested parameters by a redsea freshtest kit: dGH=12, dKH= 4 or 5; pH straight from the tap measured 8.0. When tested in a 1 week old low tech with aquasoil the pH was around 7.4
I dose EI, pressurized CO2 inline atomizer, two koralia 1's, 37 gallon tall tank, Eheim 2217, 50% weekly water change
Can I keep Blue Rams? does the electric variety matter? Is there something in these measurements that would make it difficult for these fish or am I way off track and should be looking somewhere else for the issue? CO2 has been no problem, O2 problem has been resolved, other fish are healthy (cardinals, SAE's, furcata rainbows, otos, amano shrimp) I had lost some shrimp too frequently for a brief period a while ago, but I think that was due to my oxygen problem.
Should I consider some sort of conditioning of the water? peat? acid buffer? RO? I've been looking into saving for a good RO unit like a seachem pinnacle RO/DI. Is it necessary if I want to keep blue rams happy and healthy with my tap water?
as always thank you for taking the time to read and post.
