This is my on going battle- Low pH & alkalinity with high phosphates. 75 gallon tank.
Today’s water tests:
Salinity - 30
Gravity - 1.022
Ammonia - 0
pH - 7.83
Nitrite - 0
Nitrate - 5.0
Magnesium- 1350
Calcium - 400
Alkalinity- 7.4
Phosphate - 0.236 ppm. 77 ppb
In the sump, I have Chaeto in first section, a cylinder of Co2 media connected to the protein skimmer & a reactor with a 1/2 cup of carbon & GFO.
I just added some salt water to the ATO today since it’s a little low too, I think I’m having a lot of evaporation going on now.
I did a 20 gal water change last weekend, I use Fritz RPM salt.
Thanks so much for helping me work on getting these levels were they should be & hopefully keeping them there.
