<p>A low KH is bad. Nitrification lowers carbonate levels. you will need to supplement. I have been adding calcium carbonate and potassium carbonate but i'm switching over to a new product. ROCK DUST. I cant seen to find out a hole lot about people using in in aquaponics but i contains everything that i had been trying to supplement. I bought Glacial Rock Dust. There is also rock dust from portable farms. They have been using it with great success this year. </p>

Thanks for the suggestions Bart. My nitrates are 30 and the system is 2 months old. I only have 3 tilapia in it as I lost quitea few in a smaller system. I suspect my calcium is high which would explain the 411 GH reading?

Hi Fred, I had some issues that sound a little similar back in the spring. Here is a link to the discussion on KH and I will get the link for nutrient issues in a second reply.<br></br>

It will depend on what you are trying to grow for sure.<br />
<br />
What are the nitrates at in your system? How old / mature is the system?<br />
<br />
Good luck
