Mine= $3.27 from Elmers , My wife "understands" about the hobby - she knows it helps my stress - so as long as it is "reasonable" she is pretty good. I have been talking about breaking down the 90 and just having my sons tank, and the office tank, for a while. Waiting until I can finish remodel in living room and then setting up the 180 I got from Starfiretank - she actually thought that was a bad idea- "just wait until you have the 180 up and running and then transfer the inhabitants , then take down and sell the 90. WOW- she has been listening and learning, all this time I thought she was ignoring all the reef talk around her. Who would have "thunk-it".
