question gurus...
will this work?
we have a 250g plastic tank, pic below, that we plan to submerge halfway to the river at the back of our house. with the cold water from the river, we're thinking that it can make the water in the display tank cold also. of course the plastic tank is thoroughly sealed. the 250g tank will be braced with hallow blocks for protection. a pump to get back the water to the 100g display tank and just an overflow back to this 250 gals plastic tank submerge halfway. distance of the two tanks is roughly 20 meters.
this project is just in the conceptualization stage. we're thinking that this might be more cost effective than digging a 6ft deep cement sump, water proof it, etc.
comments please.
thanks
