Happy days. Grow beds filled with hydroton clay balls and Bell siphoned working a treat. Not sure if pics post.

Just wait a few days and then connect up the fish/filter part. Nitrates very high at 150 ppm, so system seasoned and need to get some plants in.

 

 

 

 

Nice one, I have done 11 years research and tested a system in Pattaya for 8 years. Pretty similar than yours with good results.

The System must have been matured if I read your levels and by now it should run balanced like a clockwork.

 

One thing caught my eye is Blaehton (hence made in Germany) which are heavier than the cheap Chinese made clay pellets which are never sinking.

Floating pellets in a ebb/flood grow bed it is just what you don't want.

 

Will you please be so kind and answer me the following questions? 

 

1. Where did you get them? 

 

2. I developed a greenhouse cooling system which asks for a quite big size pellets in diameter for best cooling results and perfect would be if they are big, but stay within a range of 2-3 millimeter in difference.

 

3. I see that your water is only returning by gravity. Do you use anywhere Vortex Nozzles where the pump feeds the grow beds? This did in my system the trick by increasing the growth rate of my fish significantly. But I was building the other way around, fed by gravity in the grow beds and pumped into the fish tanks above the grow beds with vortex nozzles. 

 

Cheers for any reply
