| Hello, I like many things in your design. I like the settlement chamber to bead application much better than straight bead filter. Also like the bio is seperate from the mechanical filtration. I know that you like Matala and think it is a great submerged media but personally like aerated bio reactors filled with K1/ Kaldness these days for even lower maintenance and self cleaning - no mats to clean ever and I also like the aeration. Just something to consider.
I also would upgrade all of the 1 1/2" lines to 2" lines. The cost difference is minimal and the benifits are there.
One more design criteria thought and that would be to use two pumps instead of one. One pump on the bottom drain circuit and another on the skimmer circuit. The redundancy is great if any problems occur. I would also suggest that each pump is on a different breaker in the house electrical pannel. If one does pop the other can still be working. The bottom drain feeds the TPRs for cirulation and the skimmer would feed a waterfall or bakki shower to return like a waterfall.
Not here to say to change everything but just a few comments for your consideration.
