Very impressive setup! If the Euro Reef is just a temp setup, you could have gotten a better deal with an ASM. Same needlewheel pump, same design, just different acrylic. Since a skimmer isn't under any pressure, lower strength material works fine. I used the ASM on my 340 gallon for years, fantastic product for the price!
If you decide to sell the Euro Reef once you get your dream skimmer, I may be in the market for a big skimmer by then. Keep me in mind as I will be looking to "recycle" as many used parts as I can find!
Once again, your build looks great, I am following this!
