Does it work on 3 gallon carbon?

It will siphon yes, however it's designed for one gallon glass jugs so it won't reach the bottom of your carboy. Your best bet is to go for the standard auto siphon which will work for plastic buckets as well as 3, 5 and 6.5 gallon glass car boys.

Depends on the size and shape of the carboy. The smallest siphon is not quitelong enough to reach to the bottom of a standard carboy. That's one with the narrow neck that fits a bung stopper. The diameter of the siphons is the same. I wound up getting the medium length which worked better for me.

Well it overheated my 5.5 gallon and killed my fish so it would probably do the same to a 3 gallon. Please do not buy...

Carbon I would at once every couple months, my method with all filters and water parameters is if it's not broken, don't try to fix it. This filter is horrible though, both replacements leaked about 3 gallons of water on my carpet, spend an extra hundre and get a fluval 206

I think so. I didn't have a one gallon fermenter at the time, so I used a 3 gallon carboy.

I used it. In a 55 gallon tank with some succsess. The diffuser works well but u may want to look into a co2 waterfall.

I am not sure, but I think it would work on a 3 Gallon jug, you would have to hold it while it is dispensing the water. The stem is meant for a 5 gallon bottle (Jug) You might be able to cut the stem shorter so it can fit properly.

I think you will find the amount of air per minute (CFM) is not large enough to power the polisher. That polisher uses several CFM and requires at least a medium compressor, and the three gallon is likely too small.

Yes, I use it on a 29 gal tank. It works great for cleaning and water changes.

it does, I converted a a 55 gallon plastic barrel and fill it once every day or two. But it also will depend on the number of drip line you run off of it. My trees in central Texas love the barrel.

It does nothing....carbon will remove impurities if water or air are FORCED through it....this simply floats around & does nothing.

There are cheap filters, but bio spheres, carbon, and or anything else you would use, you would need to get yourself. I recommend this filter though. I have it on a 56 gallon and works great. Worth the money compared to more expensive ones I have used.

If you mix it according to the instructions it only makes 8 gallons since it is only 2 oz. I use less than the instructions, about 1/4 the amount, it seems to work pretty good.

I have only used 5 gallon..I would assume you could use a 3 gallon as long as the three gallon is tall enough so the tube that draws the water up into the unit can fit..the tube is as long as the height of the 5 gallon bottle and not adjustable. .hope this helps

I have a 36 gallon tank and, although it works, it does a minimally good job. You need a commercial system.

Yes and No. It can work but it would be best if you got an on/off valve for you CO2 Bottle.

you no longer need carbon if you run this. and this has to be replaced every 2-3 months rather than carbon once a month . I run chemi pure in both of my reef tanks. (4 years established both)
