Alright so maybe I'll do that then. I'll take out half the pellets. Add a little bit of phosguard and slowly swap em out. How long of a period would you say before its completely switched out?Phos gaurd is strong. It's for removing phos so it's that or Gfo. If you use it, use less than the recommended amount. I wouldn't cut off the pellets at once. It's like a steroid/drug. You can't go cold turkey, you need to slowly get off of it. Which is why I said cut the pellets in half.
And is phosguard a pellet or like a bag of carbon type thing?
