but then again...they can be used on a bigger tank if you decide to upgrade!!! as my dad says "buy it once and buy it right"!!
 
I don't see how its overkill. I have the diy reactors on both my 29g.

I wouldn't run my CO2 through my canisters anyway. I'm pretty serious about my CO2 so I am adding quite a bit. A nice big bubble could easily build up in the canister and stop the flow and burn out your motor. It also makes noise when you have air in the filter. A DIY set up or a very low bubble count would probably be safe, but I would get an airlock going and burn out the motor on day one. Filters are expensive, I don't want to break it making it do something it wasn't supposeed to.

I don't like diffusers because you still loose a great deal of CO2, its a passive system, and they're delicate and the ceramic gets gunked up and need cleaning, not often, but my inline reactors have been running for 3+ years and I haven't needed to do one iota of maintenance.

I use inline reactors. Some of my more serious counterparts have started using inline pumps with a needle wheel impeller for great results. I want something that will dissolve the CO2 completely and then distribute that CO2 saturated water all over the tank.

have to completely agree I've had great results with my reactor on my 30 gallon. i built it it out of PVC and it also doubles as an inline heater, and this was all for $20 (without the heater)

learned about this on a thread on here

Needs too much to be done...unfortunately not up for it yet

glass diffuser + canister intake = best diffusion IMO (right below the inline reactor)

More interested in this method. Any comments on this one?
 
well i would imagine the bubbles are already broken up when thay go into the canister there would be lest chance of it building up in the filter and hurting the impeller. also it would probably really eficent.

if you want to go even more cheaper, then get a limewood airstone instead of the glass and it will also release tiny micro bubbles.

have to disagree there thay gum up after a while (at least mine did) and you have to occasionally buy new ones. where as with ceramic defuses you usually only have t buy one
