Compresses CO2 not PH monitored?
Does anyone out there have a setup where they use compressed CO2 instead of
DIY stuff but still inject it without any sort of automated PH sensor to control everything? I like the idea of adding the CO2 to my tank but I don't like the DIY way, however, I don't like the fully automated way either (cost and PH sensor maintance), so I tought I would do it like the DIY guys do it (simply control it via a needle valve, correct?) and use a compressed CO2 tank. Anybody try this, does it work ok in practice? Looking for feedback on the idea.

I like the idea of adding the CO2 to my tank but I I use this method. I use a needle valve to control CO2 flow to an Eheim diffusor in my 29 gallon tank. With a KH of 5 degrees, I get a pH swing of perhaps .2 daily, and I've never had any problems with running the CO2 24 hours a day. HTH |

Compresses CO2 not PH monitored?
I also use compressed CO2 without any pH regulator. However, I recommend
the Dupla CO2 monitor. I say this because of an accident when the CO2 level got way to high and almost wiped out my 55 gallon tank of fish. Now, with the Dupla, I can just glance to confirm "green=CO2 is ok" While I am at it, here is what I got for my CO2 setup, sources and other suggestions: Tank Rapids Wholesale - Co2 kits - 5-lb new steel tank with dual gauge regulators $99 (#BD435) http://rapidswholesale.net/Merchant2...tore_Code=RWOC AS&Product_Code=BD435 Needle Valve Florida driftwood - needle valve used in medical gases $19.50 Appears to be Clippard MNV-4K2 (4k2 has an 1/8 hose barb included) http://www.floridadriftwood.com/product.asp?3=51 Also needs a ¼" NPT male to 1/8" NPT female adaptor (Clippard #15006-5) to connect the valve directly to the regulator. Can probably get where you fill co2 gas. CO2 Reactor Plant Guild Power Reactor http://www.familychest.com/plantguil..._reactors.html Note some online aquarium stores now carry the larger version of this, which is what I have. CO2 Level Monitor Dupla monitor - Dupla CO2 Dauertest http://www.dupla.com/start_e.htm NOTES You may be able to buy the Clippard needle valve - MNV-4K2 from a local Clippard distributor. Check their web site www.Clippard.com To add a second 1/8-inch needle connector on the Clippard you need the following parts from Clippard: #15004 - Female Hex Connector - convert the 10-32 male inlet port to a 10-32 female #11752 - 10-32 to 1/8 inch hose Some people use other co2 reactors/diffusers. Lots of variety here so do some more research on the web. My 5 lb tank lasts about 8 months. Be sure to look at local welding supply companies and at home brewing supply stores for tank and regulator. Certainly will save shipping (partly offset with tax). -- Bob Alston 918.494.4913 "Harry Muscle" wrote in message ...

Compresses CO2 not PH monitored?
Harry,
Forget the controllers. No need for them. I inject CO2 in the canister intake at a rate of about 1 buble every 3-5 seconds. It's a 55 gal. tank with just 10 Amano shrimp - the CO2 is always about 15. My KH is 4. To me personally CO2 Difusers and especially controllers don't make sense in a home tank. |

CO2 cylinder from welding supply shop (though it's actually a food grade cylinder), pressure regulator & needle valve putting 3 or 4 bubbles a second into a home-made diffuser which is effectively just a bubble-trap in the return line from my sump to my tank. Everything very happy - and while this tank is only 18 months old, the previous tank ran the same CO2 setup (though a smaller CO2 cylinder) for several years. regards, Ian SMith -- |\ /| no .sig |o o| |/ \| |
