diffuser vs reactor questions

[themox]

sup guys,

i've been looking at ways to disperse the c02 to my tank - i'm just using the stock standard DIY set up and in terms of how to disperse it in the tank, i've got a few options i wanted some advice on! (tank is 30 litres, or 8 gallons).

option 1 - simple diffuser i bought from ebay a while back
CO2 Diffuser suction Aquarium Aquatic Live Fish Tank | eBay

option 2 - using my current internal filter's outlet and tinkering it to create a reactor - i've tried to attach the picture of my idea (nothing that special).

option 3 - a combination?

what's the best do you think?

I like option 2. That piece looks like it was made to function as a CO2 reactor.

yeah it's a spray outlet. with a DIY set up, do you think I should plug up those small spray outlet holes down the side with sealant? or see where the C02 bubbles go first? essentially in other reactors I've seen they just bubble around in the main chamber. I should probably test it as I wouldn't want them escaping from them

I'd plug the holes. The longer you can keep the CO2 bubbles in the tube, the better.

thanks bigjim, I'll give it a go
