can't believe you didn't wait and you brought home a watanabe pair--You are too crazy Sherman!
Made a little progress today and another screw up. After wrangling with the RO/DI system for hours, Sherman came over and we went through it testing each part and checking it all out. We came up with nothing....really bizarre. Sherman split and I continued to mess with it, removing parts that I don't need etc. to no avail. I finally got 3 - 4 ppm out of the membranes but my effluent was about the same.
When I was testing and switching stuff around, I had one unit going to the secondary DI cartridge and the effluent stopped running. That was a big "AHAH!" moment. I pulled it apart and turned the cartridge over, doing the same for the other unit. Finally! I got 3ppm from the membranes and 0 ppm from the effluent. Finally figured it out, and how embarrassing is that??
So that means the water I have been using has had varying degrees of nutrients in it for quite a while, and I think I can assume the problems with the coral health to be at least partially related to that.
I also attempted to clean out a sump. That has not been going well as I really don't seem to have a good method. This time I decided to remove the rubble (on Sherman's recommendation) to make it easier to deal with detritus. It didn't go so well because as soon as I removed some rubble, the water totally clouded and I couldn't see what I was doing. I got out about 10 - 15 lbs. and then pumped the water out of the sump while it was full of suspended detritus. It is really bad to be honest and I need to make this a weekly routine.
So once I had the water removed, I re-filled with fresh SW. Because it was still very cloudy, I then ran a Mag pump into a 25 micron sock to help clear it up. I let it settle for a couple hours and then fired up the return pump, only to seriously cloud the display again. Dammit!
So I still don't have this down and it is really bugging me. I did notice some slimy filaments coming out of the rock structure while the tank was cloudy, and also saw a wrasse eating it...***??? :lol:
