I was just wondering how everyone is keeping there silicates down while maintaining the correct phosphate level without adding RO. I ordered some phosphate remover to remove the silicate but don't see the point in replacing the phosphate it removes when its just going to get removed within 10 hours or so later. I am currently having some diatom issues and need to get my silicates at bay. I do dose with Gympsum (CaSO4) which contains silicates...i was thinking about switching to something else to dose with, any suggestions?

The only thing i can think of is when i do water changes to dose my CaSO4 at the same time then run the phosphate remover through my filter for 24 hours and take it out and dose with phosphates to replace what was removed. So pretty much i would only run the phosphate remover for 24 hours a week right after water change...

Thanks for your time in reading this.
