Amazing. Great to see these sort of posts, to remind us that at the end of the day, it is actually all worth the time, and effort.
Great progress shots.
Got the tank builder and plumber here later today. Trying to finalize exact layout, and resulting plumbing. Core driller will be here at 7 am tomorrow, so need to be very clear on which holes to be drilled where, through the side wall, and into the basement.
Notes :-
Center Over-Flow box - offset from center though.
Reduced depth from 90 cm to 85cm
Seriously considering a 'Step-Down' of 30 cm at one end, to a depth of 115 cm.
Plan to glue a row of rocks along the drop off edge, to hold back the upper level sand.
Same for overflow box - will glue small rocks to the box side, to hide it, and maybe add a ledge on narrow side.
Pump and plumbing for main circulation to and from sump in basement, is not too bad. Just trying to work out the pump and plumbing today, for a closed loop pump for internal circulation within the tank.
I intend to cap it off with Lesley's great idea for the hood raised with actuator system hidden in the ceiling.
So a full plate - comments, suggestions or whatever , as always, most welcome.
