How deep is the grow-bed sg. This is relevant because you will need a decent surface area to grow the plants needed to pull the nitrates out of the system.


I will probably be making the growbed with wood frames and pond liner.

To start 3 beds:
200cm x 120cm x 30cm = approx 720L each or 2160L total

I should note, once I work out turnover, as others have suggeseted I will add some extra capacity and redirect some straight back to tank to provide surface agitation for better DO levels.

No worries - this should be plenty for your 100 fish provided you plant wisely.
