Last minute advice?

Ok, I'm going start working on the 125 this weekend ... after the being at the cubs game of course ...

29 gallon sump with acrylic baffles. (going to "tack" into place with superglue then silcon around)

The Mag 3 lines will all be returning into the skimmer chamber.

I'm going to make the inlet "break away" so I can unscrew it just in case, same with the return.

in and out will have ball valves to be able to stop / reduce the amount of water.

 

I now know the horrors of doing that ... not easy at all.

OK, well, I got the fuge built, no where near what I thought I was going to do it as but still I think it will dominate.

I build part of the CD, the coil in 2.5 feet of 4" PVC and about 75' of 3/8" tube. I had a top but decided to change it to the same thing I used for the bottom so that needs to be purchased.

The skimmer is going to be outside the tank now and going to be going back into the inlet.

Not sure how I'm going to plum up all my mag 3 and 7 yet. Was thinking tubing instead of PVC after seeing it all in the tank ... just seems easier to get right. Good idea or bad idea?

Did a water test on the overflows with just a pitcher of water in each and decided i needed to clean out the corners and get new gaskets before I fill up the tank. ( good thing I tested this before I attached the PVC ).
