Nice post @Dewald, I cant wait to try it out this weekend. Quick couple of questions, does it have to be 2 bottles? is the bottom bottle (500l) acting as a way for some air to seep in to the 2 litre so as to not create a vacue, or is this just accopmlished buy the barbed adapters area (essentially a minute controlled leaking in of air)? Beats the way I was doing it with a pump to build pressure and force the water out, and then constantly having to adjust the air flow, ugh what a pain in the butt, this looks like way less maintenance.

awesome Dewald!!! So our plan worked! @Nes,the problem is that we can't find a drip set to buy locally,the 2nd(500ml) is used to control the drip flow! All the betta,tetra and betta guys! Here's your solution of feeding the tiny fry whole day long,little portions at a prolonged rate.We know what happens when you over feed!

My post did not go through. Hope I am not double posting. I said I do not understand how the dripper work and would like a more detailed explanation, especially on where the air goes in and how it operate.
