The Ehiems are used since the client works 6 ft away from the tank(I told him I thought adding this tank in his office was a bad idea.......he's going to reduce production and not work, then will not be able to pay his bills). This is for noise factors, we really cannot remotely filter, so Ehiems are quiet and easy to service in this environment. There are 2 x 40 W UV's, 2 of the ehiems are heater units, and then the other's go to 4 x CO2 reactors.
I'll detail the lighting out in about 4 weeks once we set it up more.
Still some work to do.
I suppose I could sound proot a different filter system, but it would cost more than the filtration system cost to do correctly. I had to do that for a client and learned more about sound proofing than I ever thought or considered possible. That is an "art".
