You're welcome David. This was included in some additional information that Kev emailed to me. I don't think he'll mind me posting it, and it may already be on the new website. Media removal really depends on where you start at on phosphate and nitrate. It may help, or it may confuse LOL! I'm dosing at the 2 ml/25 gallon level, adjusted for my additional sump volume of 10 gallons, I've been adding 2.8-3 ml daily.
My phosphate was at 0.36, and nitrates at 2 when I started. Phosphates at 0 now, & nitrates still at 2
I had some SeaGel in till yesteday's test showed 0 phosphate, so I removed it yesterday, and just have carbon in now.
