Review on Kent Marine AKMMHIS60 Membrane 60 Gallon by Ashley Rice

I've had the membrane for a week now. I washed it for about an hour expecting a 95% marriage. It started at 91% and didn't improve. I'm still stepping into my DI @ 26 resin which is way too much for my reef tank. My Tap TDS is around 300 so I should be entering my DI at 6, no more. I expected much better results. If it doesn't get better, you need to replace it.
