Water Testing and System Review

Took some water samples today.  Looking good. (See side bar for details).

System appears very stable with 7 fish in clean water and plenty of veggies in the grow beds.

I've also checked the circulation volume, can do it from pump data but also checked with just simply collecting the output to each tank for 30 secs each. Throughput added up to exactly 2 litres for 30 seconds. Thats 4 litres a minute so 240 litres an hour. Tank volume is near 180 litres so an exchange rate of every 45 minutes. Very acceptable. If anything a bit on the fast side. But I'll stick go with the pump system I've got. You know the expression, "if it ain't broke don't fix it".
