interested in doing a build like this in the future with those radion lights so i just want to tag along... i have a 75 now and want more lol..i have two mp40wes and i want those lights just cause they can communicate with each other.. i think you might need like 4 of those radion light fixtures bc of the dimension of the tank... this is gonna be expensive... anyways im following... your plumbing looks good wish i understood it...
