Eheim CO2
I just found that same link myself. While Eheim carries a real good
reputation, it seems a little expensive compared to what I believe are equivalent quality competitors. "Bob Alston" wrote in message news:bDvmb.84834$Ms2.56466@fed1read03...

I don't think that Eheim makes co2 systems. -- Bob Alston bobalston9 AT aol DOT com "gizmo" wrote in message ... Did you take a look at the Eheim System ? http://www.eheim.com gizmo "Sidney" wrote in message news:04%lb.40960$hp5.10546@fed1read04... I'm looking for a complete CO2 system with a solenoid valve, without the CO2 bottle/tank or a PH controller (yet ;-). These three companies seem to be the "main stream" setups and are all relatively close in terms of price. Are they relatively close in terms of performance? Finding factual differentiation has proven fruitless. Is chrome plating worthwhile considering the minor perceived cost increase? Should I just shop based on price alone? Are there other places I should look? Other brands or options to consider? THANKS! Sid |

Eheim CO2
I had the Eheim CO2 setup as my first... recently I replaced it with a
Tungze. 1. The CO2 tubing from the regulator out to the diffuser isn't 4/6mm diameter, it's smaller. That means if you decide to use a soilenoid or use another diffuser you will have to find a way to couple the hose sizes together. I ended up jury-rigging something together (could not find standard-sized adapters for this purpose), but was never really happy with it. It looked messy and at first was prone to leakage. 2. The diffuser is a ceramic tile design. I was never all that thrilled with it's performance, and lately there seems to be a big push away from this type of diffusion (e.g. Eheim no longer makes it). 3. There's only one gauge, for tank pressure. No gauge between the tank and the needle valve. 4. The needle valve isn't the greatest... Instead of a thumb-screw design you have to use a small screwdriver to make adjustments. OTOH once you got your bubble rate dialed in it does not tend to fluctuate. It did take me awhile to acheive my 'ideal' flowrate, but once I did I didn't need to touch it until I replace it! 5. It's expensive! Maybe just because I purchased it several years ago and the prices on competeting units have dropped, I don't know. Honestly I didn't price other setups because I was going for the Eheim name. You really pay for that name, although usually it pays off! "Sidney" wrote in message news:mmwmb.42272$hp5.3791@fed1read04... I just found that same link myself.

Eheim CO2
mmm....
I am still thinking of upgrading my system to the Eheim one. I do have a ceramic diffuser - seems a ok for me. The only good thing for me is that their gas bottle is big enough for me 4-4.5 KG. Well I'll rethink as well. (but there are no other alternatives for me unless I'll go for the DYI) Gizmo "zeek" wrote in message om...
