The PH Effect

I have a high ph (8+). I seem to be limited on my choices of plants because of it. I was wondering what effect would it have on plants that require a lower ph?


Thanks

No, it won't affect the plants you want to keep. gH/kH play a larger role in plant survivability.

High pH typically means that you also have a high kH/gH, which WILL impact your plant and livestock choices. You do need to get your kH and gH tested.

I just tested them and got gH 20 kH 10. Does that limit my choices?

Yikes.

Is the kit right? Expired? Are you doing the test correctly?

Whats the substrate in the tank? Are their rocks for hardscape? Have you added anything to the water (ferts, boosters, etc)?

These could cause the Kh and Gh to climb.

The substrate is flourite. The rocks are lava rock. I add Seachem flourish, iron, and potassium. I have diy yeast generated co2. The test kit is a Tetra test water test set. When do the test kits expire because my kit is fairly old?

All those readings are in line, so my guess is that you truly have liquid rock water. Your options would be to work with that, and choose plants and livestock accordingly, or get an RO unit or buy RO water to dilute those water parameters a bit.

I can get RO water for free. I'll try a 50% RO 50% tap and see what difference it makes. Thanks alot for helping me.
