I have one of these and for the last 6 years has never failed http://greenleafaquariums.com/co2-regulators.html

Fred Guy at the Calgary Aquarium Society I think still breeds them

You can just pick up the float valve/auto shutoff and use any pump.

Try Concept aquariums. They can make one in about 3 days.

Just plain old gravel with an undergravel filter

Finally found the one for my eheim. Hope this helps. If it pop's out from under the retainer ring l get lot's of noise and the only way to get water movement is to hold down the prime button.

Can't see it on the parts list but it is the "black" flexible elbow in this picture. If you want send me a pm and you can come take a look at my 2080 or I'll drop by your place. I'm in Woodbine.

On the bottom of the motor/head part ,the ring you had to remove to check the impeller is a cream/yellow elbow feeding into the impeller. Pop the ring back off and reattach the elbow. 99% sure that the problem

I have heard there are iron test strips but no idea on accuracy or availability.

I would be more worried about iron or rust. You could put it in a pail after checking ph, hardness etc. And see if it changes in a week.

Pieces or big al's. But only get the small tube because it is expensive.

Orca underwater black silicon. Have used it in the aquarium with fish in with no side effects. Only problem is getting it to stay on something wet.

I hate thick stone. Only because I get to carry it.

Granite is a fine grained metamorphic rock. Marble is calcius limestone. The only place you might get away with marble is in a saltwater tank. A slab when it arrives is about 5' X 9' and 1 1\4 thick. Sizes very but not usually the thickness. The edges can be (asside from cut) broken, hammered or chiselled to get the edge (and\or shape) you are looking for.

I work in a granite shop. If you want granite pieces ( ie; sink cutouts) just let me know. Price FREE.

So what do they do if one of their fish kills another? Kill it? Now what about the store employee who did the killing?

Well I could type out a 3 page reply or you could just send me a pm come by my house and you can see the led set up I have.

So how would you feel about my 15 watt on a 72 gal overkill wise? I think uv's are great on fresh water tanks. The only thing my fish die from is old age.

Duckweed is also awesome IF you want it. Otherwise its a nuisance.

Led's? Gee news to me. I was getting ready to do it on aquarium plant reproduction, but if you want to give one on LED's mine can wait.

I thought there was a law against slave labour. She would have her doing all the water changes.
