Slatted shed design

I know I’d like to have it too but can’t justify / afford it, if you had a few tanks it wouldn’t be as bad, the pump is €10,500 +vat, that’d do a few tanks, just can’t justify it for one 5 bay tank

Anyone experience with slabs over a tank. Whats the life of them. What weight they take. Ive no experience of them and have reservations on their longevity

The main problem is if you take out 4 ft out of the tank most agitators won't work as the marine bearing wont the covered. Next step is to put more water into the tank.

Really there is a few options, get a long agitator for yourself or contractor, or aeration. Might be worthwhile putting the pipework of it into the tank, with the long term view of putting an aeration system.

What about a sump built into the floor of the tank?, always 9" or so of slurry left in tanks here after emptying

Only left with around 3 inch of slurry on my 8 foot tanks sucking with 1150 Abbey tank. Must be thick if you've 9 inch left.

Don't think so tbh. 2 different 3 bay tanks here both suck down to 3 inch, well mixed and pipe is twisted about the floor any direction to get all sucked out.

Contractor spreads for me so as soon as 6" pipe starts sucking air spreading is finished ! Slurry from other end of tank then flows down and levels off, would normally be thick enough too

Yea I do my own so can take the time to empty fully unlike yours.
