I have melev's reef 100gph Ro
I was curious as to when I needed to replace especially the DI
filter part. On his website he says 6 months to a year but also mentions color change and it may vary due to the lack of or the amount of impurities in the water. So far I've made about 50-60 gallons total and I'm seeing a color change ( see below) - is this normal? Or will I have to change the filters sooner?
I read a TDS
meter is the best way to tell, but was curious about the color change. Add TDS
meter to the to buy list!
