That depends on the lighting. Sorry, remind me what your lighting level is again?

18" is arcadias are 15w so you won't see your plants pearling unless you get an extra tube to make 30w which will give you 1.5WPG which still may not be enoughThat depends on the lighting. Sorry, remind me what your lighting level is again?

I don't actually know what watt the lamp is, and it doesnt say, all it ses on the tube is Arcardia FO 15-(18") plant growth lamp, and the tank is 20UK gallons.
Well done on making the DIY unit - it took me ages to get the lid sealed properly!
I run 2 DIY units like yours into my 20 gal via my external filter uptake pipe and I have 50W and STILL I have very little pearling at all! The plants all grow well but I do have trouble getting a carpet going. You will have to up your lighting I think to get the effects that your after.
By the way, that DIY bottle looks very full to me. You may have to watch that it doesn't leak yeast mix into your tank. In a 2litre bottle I add 1 pint of sugar to 1 pint of water with 1/2 tsp of yeast. Fills it up about halfway.
Good luck.
Sorry about the leak, what a shame. You've probably already done so but make sure you do plenty of water changes to get rid of the yeast mix from your tank.
Wow! You got them to pearl, that's great, wish I could achieve the same. What ones are pearling? - I can only get my hydrophilla to do it so far.
I'm thinking about do this very same set up for my 125L tank, read up on it. But I've noticed you have your CO2 going straight through to your filter without a difuser. Now here's the silly questions : do you need a difuser or are you using one thats not shown in your pics??
Also is that little blue device joining the two pipes a one way valve? How do you regulate how many bubbles are produced?? and if I did the same mix, but put it into a 5L bottle (for safety reasons eg. stop it going up into the tank) would this be acceptable??
