Now the heats here, I'm looking for advise on how to run a pump for a 7000 ltr round tank for swimming in.
Basically, Im digging a hole and chucking in a tank.
The filter would run during daylight hrs only, hopefully off dedicated solar panels. Am I thinking too far outside the square? Apart from not being able to do laps, what else is impossible?

Plenty of DC pumps around that operate directly from panels. Burying the tank will moderate diurnal temperate swings, but once the ground has warmed up, it will keep the water temp higher than it otherwise would be. Shade the ground around the tank, and the top of the tank, to keep the water cooler.

7000l isn't very big, I've got trout in tanks buried in the ground here- 4200, 4500 and 9500litre- OK for a dip to cool off I guess, but no room to swim!

Got to have an "approved" fence if it's in the ground, don't know about the rules for above ground.

I ran a Sand Filter/Pump (85w) for our 8000l AG pool last summer off a 200w portable solar panel, a 260Ah AGM, and an inverter. Most of the time it was fine, but there were a couple of days I had to revert to grid AC.

My biggest problem was heating it. This year I bought a couple of Sq. M of pool heater. Much better. Killing the grass though! Have to mount it above the pool (one day). At least the grass isn't growing under it. :lol:

Pool fencing rule (was, as I understood it) if the AG pool is 1.2m, and there's nothing to climb on, it's OK. Not going to stop me slipping, falling in off the ladder, hitting my head and drowning though. :o

Get a solar powered pool pump available as a solution, parallel with the regular pump and with applicable check valves and all done, should be years hassle free operation.

Thanks for your responses. Very good as usual.
In reply, I don't want the thing too big, I just need to cool off. After Saturday up there, I would have dived into the toilet if it meant cooling down some, but I couldn't fit.
Another idea would be to line a hole with several layers of visqueen and then place sandstone blocks around the perimeter and the base. Top it off with flagging as coping and there you have it.
