Reminder to change your RO/DI filters!

Over the last few weeks I've noticed some SPS bleaching in my tank. I've been pretty busy lately with a lot of projects at work, plus the birth of our first child, so the tank had to go on autopilot for a while. About the only thing I have been doing regularly for the past two months was replace top off water and feed the tank.
So tonight when I went to get more top off water, I checked the TDS. The TDS coming in was 373. The TDS coming out was 356. And then it all clicked.
I replaced the filters, dumped all the "RO/DI" water I had in my reservoir, and have started replenishing my water supply.
I feel so stupid for not checking this earlier because I am losing some of my favorite colonies in the tank!
