Got an icp test thru ATI at the 3 month mark. Results was concerning.
There recs was to change 20 percent water volume 3 times in a week.
My goals was to locate the source, remove the metals, improve my nutrient situation.
I had RO water quality issue so I waited until I got that fixed. My tds was 001. It had only been 001 for a short time and no water changes was done with 001 water, only top off. Ro water had nothing show up on the test except for high silicates. Eliminated RO water as source of Metals in tank.
Went thru my pumps and gear in the tank and found a magnet that had metal shavings stuck to it that was rusty and in the water. And a light fixture that had rust coming out of the joint where the light gooseneck screwed into the bracket for where it attached to the glass.
My RO situation was remedied after a couple week and now I have 000 water again and I've done 2 water changes at 12 to 15 gallons each. (Water volume between 50 and 60 gallons)
I added Cuprisorb (100 ml) to my carbon reactor, with my carbon. Also added 1/4 the amount of gfo to my gfo reactor Sunday(first time running gfo).
Tested phosphate at more than 200ppb on Sunday night. After the first water change and after gfo was online for an hour. Tonight changed 13 gallons of water and then retested phosphate at 108 ppb, and 119 ppb.
My goal was not to ever make huge changes so I was reluctant to change water so much, and reluctant to use gfo. But I wanted to make a good attempt at removing metals. (Carbon, cuprisorb, and gfo.) Now I've stripped away about half my phosphate way to fast and am worried this could be a bad situation.
I have more info.. please ask I feel like I've made this too long.
