Just replaced my DI resin after about 1 1/2 years. The color did not change at all compared to new resin but I figured it had gone too long and I am having some pest algae issues. My water is really good out of the tap, like 3 tds so maybe the resin was still good? Did I throw away money?
The output tds is 0 but seems like I've had an issue before where algae just started growing despite 0 tds.
tank nutrients currently nitrate 6 ppm, phosphate 0.06
main pest is cyano
