Hello all...newbie in South Texas checking in on my new IBC system. I have a long way to go but am learning new things every day.
I have three totes cut and one up and running. It was started on May 01 and today I did my first water test. No fish yet and a few house plants to start it off.
My P H is 8.8
Ammonia is 0 ppm
Nitrites are 0 ppm
Nitrates are 20 ppm
I have two large aquariums in my house and when I did a water changs, I used that water to try and kick start my aquaponic system.
What can I use to bring down my P H? My tank is about 200 gallons water and river rock in the grow bed.
Thanks guys for the reply. I will give it more time to do it's thing. And yes, the river rock in P H neutral by the vinegar test. Did a big handful at a time in about a half gallon of 5% vinegar and no bubbles.
