Hey Jp here i am. Sorry mail box full. not on here as much.
Like the others pointed out that there would be many variables involved.
When it comes to Marine live stock the cost are much higher or at least when I had the salt store going. Now with the LED lighting in play the cost could be coming down as pose to running Metal Halides etc..
I have over 400 tanks & about 21,000 or so running between my retail store & the hatcheries. I am in Cleveland so the cost is a bit less then in the suburbs. My cost have been going up though & I do not see them going down much. I did put all new store front Windows a few years ago that helped & also have replace a old furnace with a 95% effecient on the other show rm & hatchery. So I have tried to reduce the cost & has helped & will help knowing it will only go up in the future.
I just replaced my old 1/2 hp blower with a new 1hp & is on a 220 line. Its more effecient & should run me around $40 a month & runs about 350 tanks or so with much more it can run. I will add some more racks on to this new bigger blower so I can take off another air pump.
Right now my cost are about $1000. a month or so.
Now my ? is why you want to know or the research? You plan on opening a shop?
