DIY Sodium Phosphate

[timqmana]

Hi Randy,

I am planning to make my own phosphate solution for dosing in to my tank. For some reason the Amazon links from your older posts are not working for me. Would this food grade sodium tripolyphosphate work for making my own phosphate solution?

No, I do not recommend tripolyphosphate. Kits may not readily detect it and bioavailability me be limited.

The one in the previous post is good.

Thank you both!
