Hey guys I’ve been Mia a few years. With a huge remodel on my house the tanks all had to come down except my 24g led nano cube. It’s been up and running but not fish or corals just keeping rock and Sand alive sadly. Have a few questions as I’m going to start this back up and eventually get my 120 fatboy going again. -does di resin go bad from sitting? My tds meter is still showing 0. Or should I just replace it? I will be doing the other filters as well. Do I need to worry about the membrane? The unit is at least 8 years old but tds ends up 0. -I have a bag of salt left and of live sand. Still factory sealed. Do they ever go bad? Or since they’re sealed good to go? -I plan to do a 75% water change when I move the cube and reset it up where I want it. Then wait a little and do a 50%. Try to get parameters back where they need to be as it’s been dormant. Is there anything else you guys would do? Like I said been running but just top off of water. -what is the best way to clean up old pumps and skimmers I unfortunately did not put them away the cleanest. As I had so much going on. I know I’ll have to probably replace some but what is my best bet to try to get them clean? Vinegar and water and let them soak them run? Thanks for the input guys!
