Let’s make this long story short. I’m stuck to my 4 car garage for my fish tank, I don’t have a gas heater in there yet but am going to look into it (have to add a gas line around the outside of my house to the back side of my garage). I do have the heater just need to extend the line. I have a 150g cube, 30g sump and 125 sump turned into a refugium/frag tank. To heat all that water I’m using 1500w and it’s turning on every 30min, needless to say my electric bill is stupid. Does any one have advice on how to costly fix this issue. I can insulate the garage doors but will only do so much since the garage door is opened every time the wife leaves. My water heater is in the basement and not possibly to do a pex line (or whatever) some do. I do have a bathroom along the opposite wall of my tank… Not sure if I can do something with the hot water some how? If nothing else I’ll have to decommission the 125, I’d love to be in the house and bought the wife this house so I could but we can’t compromise. Any ideas however crazy would be appreciated.
