I tested the water in the tidal system tank...........perfect.
We had started off with a very high pH reading of 8.0 which I resolved by the addition of 200 litres of water from the other fish tank plus a litre of fresh lemon juice. It's now around ph 7.2.
Interestingly, we already have a respectable nitrates reading of 40+......probably the result of the water transfer and because we'd used the gravel/expanded clay media (from the square metre grow bed) to fill the satellite pots. I'd also tipped the contents of the pressure filter into the grow beds a few days earlier.
The float valve that controls the pumping cycle on the new system is not working as well as I want at the moment.
