Diy Co2

I just setup a little diy system for a 10g in the bedroom... due to plant addiction. and I was wondering instead of a diffuser has anyone used one of these elite mini filters? it has an airline tap in the top of the flow

http://www.amazon.com/Hagen-Elite-Un.../dp/B0009YD7D4

I have one from a alien tank my nephew used to use

I've had it running from the co2 with a check valve in the middle, I don't believe it will pull a suction but it will take the pressure

Lemme know what ya think please, btw no fish in the tank yet if there ever will be.

The air inlet you're interested in using won't work well for diffusing. What it does is pull large bubbles into the water path and spit them out in relatively large chunks. You'd do better to have the CO2 feed directly into the inlet of the filter. The impeller will smash the bubbles to tiny bits. The downside is that it will be relatively noisy.

I use an elite mini as a diffuser. I poked a hole in the side of the bottom part and ran my line underneath the impeller. I also removed the foam from inside, and slipped it over the output to further help diffuse the co2 into micro bubbles. Works great! When it comes to noise, there isn't really any. You will hear the bubbles hit the impeller, its very faint though.

Running it to the air inlet on the filter wont work near as well as this way.

Place your CO2 tubing below the Hagen Mini Elite Filter not on airline inlet.

Ive been using Hagen Mini Elite Filter with excellent result. I place a nano glass Co2 diffuser just below it. The filter suck all the bubbles coming from the glass diffuser and I get double diffusion.

I have 5 Mini Hagen Elite Filter. Running 2 and 3 brand new back ups.
I just love this filter for CO2 diffusion.

That $8.24 on Amazon sold by Entirelypets is a good deal. I think it's the one I purchased few mos ago. I bought 3 from that seller.

The filter usually sells at petco retails for $13.

Definitively can tell a difference with the co2 going into the bottom of the filter the bubbles are probably 1/4 of the size they were which wasnt very big.

I have the older version of the elite mini filter.
Looks like this.

It's hard to find this one.I have had it for 2 years.I think i ordered it through
petco or petsmart online back then.Oh, i got it off ebay.
This gadget works great for a reactor or diffuser.

I was able to find one on ebay for $10 shipped.

I shoved a chopstick in my airline tubing, then cut a small hole in the plastic grating and put the tubing through there. Before I was using a cheapy airstone to reduce the bubble size before being chopped up by the impeller, but I found that a chopstick works better and is much quieter. But yeah, it works great for diffusing CO2!

What's the difference between leaving foam in it or removing it?
