FIGURING OUT WHEN AMMONIUM LEVELS ARE TOO HIGH
FIGURING OUT WHEN AMMONIUM LEVELS ARE TOO HIGH… September 10, 2012 I had a minor freakout at the polytunnel today when on testing the ammonium levels were at 3mg/l. So why are the fish not even the teenyest bit dead? Here they all are – not one lost by the way since aquiring them… yet even…

Module 8 – Operate
Operate If you’ve reached this point, please accept our heartiest congratulations. You just became a sandgardener…with skin in the game. If you’re following our lead, your new system has been running for a couple of days. One of the core goals of the iAVs irrigation regime is to remove not less than 25% of the fish…

Module 5 – Setup
Set Up NOTE: This is probably the most important section in this course. Sand is the most cost-effective filtration media anywhere! And therein lies a problem. You see, if you pour water containing organic matter onto sand, the organics will be trapped on the surface where they will eventually build up to the point where the…

Module 4 – Build
Build Having selected a design and layout, it’s time to build it. Sand Biofilters The sand biofilter is the core of the iAVs design so let’s get started there. Effective drainage is essential in a sandgarden and here are your options. Let’s now consider how to put various iAVs designs together. Building the Square Metre…

Module 3 – Design
Design Every iAVs is identical to another in terms of its basic component parts and operating method – from a square metre to a million square metres. We’ve provided three system designs – each of them authentic iAVs – with the only difference being their size. It all comes down to your needs, preferences and…
