Newish tank (22 gallon using RO)
, been up for about a month with fish. Completely cycled and aquasoil is done slamming the water column with ammonia. All parameters are in normal range except GH, and TDS is slightly high around 350-400 but I'll get to that below.
- Nitrate - 10-20
- Phosphate - 0 - 1
- KH - 4
- PH 7.2 which drops down to 6.2 with CO2 on
- Temperature - 78
GH reads 0 and api calcium test also essentially reads 0. I put 4-8 tsps of Green Leaf aquarium's GH boost
after every water change (typically 33% change). It will still be 0 the next day. This dosage is about 2-4 times over the recommended requirement and rotala
reinforces this so I'm left scratching my head. I then realized because this has potassium and sulfate in it too that it may be unnecessarily increasing my TDS as well, since it stays high above 300 even after water changes. Of note is that I remember my TDS being high even before fish (and waste) entered the equation.
Fish are fine, all shrimp I've put in have died
(dripped for 6+ hours with the tank water making 75% of the total dripped water). Super bummed about this and want to try and figure GH and TDS out before I try to put more in. My last tank had seiryu stone and there was always an over abundance of GH.
- Any idea why my GH will not go above 0?
- What are people buying for GH? I already have magnesium sulfate for Mg but nothing for CA. I want to get GLA GH boost out of the equation.
- Am I missing anything else here? I doubt it but am open to ideas.
- Aquasoil will suck up GH and reduce it to zero. Yellow water is a clear sign of this. Zero GH will also likely cause shrimp to day within a few days of putting them in the tank. My wife says her GH eventually stopped dropping a couple of months in with her tank which had aquasoil. Her tank was also yellow at first and we didn't know why.
