I will say another mistake that I made with that system was running the lines through the lids of the buckets.
You’re better off if you run them through the bucket itself on the upper part instead of the lid, that way it’s easier to remove the lids if you need to
My system now has the type a lid that only part of it folds up and I can run lines through the park that doesn’t
This system does recirculate but it’s not This system does recirculate but it’s not an undercurrent type system that has pipes connecting the buckets
That bucket May not look very big but it’s a 13 gallon bucket and It holds 10 gallons of water when full
