TDS RO water and remineralization help
So first tank has gone alright so far. A planted 29 gallon tall with currently 8 Red Cherry Shrimp, 3 otto cats, and a orange dwarf crayfish. I started with 15 cherries and lost a ton over time (if your doing the math I lost 7 shrimp.) When I asked for help I got a lot of different answers and one ended up being my nitrate cycle wasn't complete at the time i added shrimp. BUT another concern was raised, that being my TDS.
Right now I'm sitting at 334 PPM, where as my Tap is 105. I was told that my substrate choice was not the best. I have 5 bags of Fluval Stratum and two bags of Ecocomplete. I wasn't liking my PH being close to 6 so I added crushed coral. My Ph has been stable at 7 now but from what I read the crushed coral has a large affect on TDS. But I've also read the TDS could be the buffering substrate activated my te tap water. currently my residence seem okay, no deaths in 4-5 days and everyone is eating. The shrimp are enjoying the new frogbit and swimming around more then ever.
So should the TDS be addressed immediately? I've done a 15 - 20% water change today with tap water. But should I just look into RO water? would that help? Should I ditch the crushed coral? I just don't want a super low ph. I read that Tap mixed with RO works for some people should I try that? Also should I use shrimp minerals and RO water exclusively?
Any input on what i should do? I know every tank and regions water is different Could my Root tabs and fert be raising the TDS to high? Also my calcium is off the charts for my API test is that from the excessive TDS caused my crushed coral? since coral raises calcium?
