Dufflight's System

[davidstcldfl]

Have you grown Pitaya before? The flowers are awesome but you gotta be a night owl.

Funny how the brain 'thinks' it see's something.....I thought you wrote.... 'Peyote'.....I've heard many claim it's 'awsome' too.....

I'm having another cup of coffee.....

Set up a small wicking bed, added a couple of tomatoes but will be using it for carrots & radishes.

The AP tomatoes are still producing(2yr old plants).

Are your toms the German green?

[dufflight]

I think they may be beefsteak, just haven't turned red yet. I have the green ones but have not tried them yet. I trimed a few leaves today and there are bunches of tomatoes everywhere.

Large ABF still running well. Thought it would need a clean by now but the water flow is still good.

This one uses half a 200ltr drum filled with bio balls and a bread crate on both ends. I pump 150ltr ish of air through it a minute. The air keeps the water moving through the media. Its located in the pool and has been running for a year or more. This type of bio filter allows me to proccess the Am & Ni for 500ish fish in 50000ltrs of water. Some of the fish are over the 1kg mark. I was expecting it to need cleaning by now but my guess is compost worms are living in it now. The other ABF I use has media that moves around and never needs cleaning. I think any air pumped into a system should go through a bio filter of some kind. The faster a system changes ammonia and nitrite the better it can cope with different fish loads. I had a seperate 380ltr tank that had water moving through it from the pool with an ABF and 400 fingerlings. The pool showed a small amount of Am but the water comming through the fingerlings tank showed zero. Since using airlift bio filters I don't get Am or Ni readings unless I throw a heap of Urea or new fish in. And then it only shows a reading until the bacteria take up the slack.

I think you should pump air before & after the bio filter. The bio filter eats oxy to work and can deplete the oxygen from the water. Giving it a boost after gets the O2 up for the fish.
