Membranes last longer than 1 year. Plus i dont run mine 24/7 like some people doThats your problem. 1 yr is WAY too long. and do some WC. watch your acros improve each time
I have a 7 stage Ro/Di. ATI ICP test my ro water every time i send it in. Nothing is out of whack. My TDS meter reads 0.01ppm before the cation/anion/mixed, and 0.00 after. I change my sediment filter, 2 carbons, and di resin when it needs it (maybe 2 months ago).Yeah, but he hasn't changed his membrane in a year, who knows about the other filters too. OTherwise, I'd totally agree. This always makes my tank better.
I am going to dip and relocate to see if that helps any. Question: Are mille high or low light? Its getting about 450-500 par now. Im thinking i should lower it.
