Was thinking 4x4 ozy.
So 200 litre res....
I’m thinking from what I know and from your guys advice that I’ll setup for 3 x 4x4 tables, (perpetually harvesting a table every 3 weeks) 3 x 200 litre res’s a shit load of clay balls and net pots.
I already have 3 big air pumps, one for each res. And I’ll order a spare air pump.
What size submersible pump would be best for a 4x4 ozy?
And yes I’ve learnt the hard way with air leaks, high water temps, not keeping res, air stones, line etc sterile enough

and another bonus to this is I will only have 3 res’s to worry about and not 12 buckets lol.
