Yea hard water nutes are for water in the 200 ppm range. It's not just your ppm it's also what's in the water. My bro has the most amazing well water and won't let me fill up tanks because I might do better than him. LOL no really seriosly.

I have a small R/O filter and used to distill my own water. Talk about a pain. but hey made my buds nice. Be sure to get the calmag or calmax.

Don't forget us, we want to learn from everyone.
