## Questions & Answers

**Q: Would the 110 be overkill for a 36 gal goldfish tank? Would the 100 work just as well?**
A: I run (2) 110's on a 90 gallon tank of exotic goldfish. That means I'm running 1000 gallons an hour through the filters on high. I've raised exotic goldfish for 50 years - goldfish are the DIRTIEST fish there are. They produce more ammonia than any other fish. These filters work great. I have some mini's - now called the 20's - which I have had for 35 + years, and they still run as well as the day I bought them. I ONLY USE AquaClear. Best filter out there! They last forever because there are no moving parts to break. There is only a magnetic impeller. In 50 years, I've only had to replace one intake tube that broke, and it was my fault! I tried a canister filter once, and quickly went back to my Hagen AquaClears. Easier to use, and as big as they are, you can use any kind of media in them that you want to use. You cannot go overkill on filtration for goldfish.

**Q: do you need to replace the filter media in time, and if so, how expensive is the whole kit**
A: I ditched the carbon early on, never clean the ceramic donut things and clean the sponge once every 6 months.  Have had it 2 years with zero issues and a very stable tank for fancy goldfish.   Love this filter.  Less maintenance and less noise than others.  I actually came here to purchase a second one for my tank to replace my old hang on the back filter.   So I will have two of these 60-110 gallon filters on my 55 gallon tank.   Sounds over kill but it’s not for them dirty goldfish lol.

**Q: Will the 110 fit on over the 1-1/4" tank edge of my 70 gal tank?**
A: 13 1/2"L X 6 3/4"W X 9"H with 4" of its width behind the tank.

**Q: How many Gallons of water per hour (GPH) does this filter handle?**
A: I am not sure, but I know it turns it over at least once per hour.  I can tell you I use it in a 100 gallon turtle tank (turtles are notoriously dirty) that is about 2/3 full.  It keeps the water sparkling clean and free of all debris all the time.  The water NEVER looks dirty.  I do clean the media and vacuum the tank once every 1 - 1 1/2 weeks, but I have been extremely pleased with this filter.  If it ever breaks, I will definitely get another.
