NO !!!!!!
I draw the line there, had a sister in law with fish tanks and I thought they stank....
I agreed to try this on small scale but it has to be out in the barn,,,besides we are on borough water here at the house,,,between the cost of water and all the crap they put in it, the fish would die,,,,honestly some nights I can smell the chlorine in it just like a swimming pool....
need to do a lot more research,,,If the electric would go out, how long can fish survive in that situation,,,,it can take us a couple hours to get to the farm at times..I am assuming if he wants to do plants also he would need some kind of grow lights inside the barn......
see what I mean,,,these are still basic questions,,,he would just dive in and figure all this out as he goes,,,,I prefer to find someone already doing this and lean on them
