Dazed and confused Yes my kids all grown gave me a 4' x 4' Led Zepplin high quality picture for the wall behind my sump. The wall is 8' long and my reacters will be (1) 36" & (1) 20" x 8" on each side of picture and the 4" run under and along the picture. The reacters set on a 16" x 14" wall with cutouts under each reacters so i can have LED lights run under them shinning up as the reacters all have a clear base. Yes i am 54 Led Zepplins my band You may be right i will have to see if a stand alone is needed. I believe in THE POWER of Micro Fana so much that i patent the design and brought refugiums to our hobby at MACNA X in Long Beach. Albert Thiel told me there that it was going to be part of our hobbies future but a few years away. I left the hobby after that for family reasons and just started back 6 months ago when i started this build. In 1998 i took down my 750 gallon reef + 150 gallon refugium and 100 gallon sump that i had been doing R&D for many years thats what helped me design refugiums. To me there is only one way to tell if you refugium is really working and that is by your fish. If they live and play around your tank inlets then it's working if not it doesn't matter how many pods you have in your refugium it's not feeding your DT.
