If you've only got one filter on your tank, don't use this one. **Q: Is there any type of "filter extender?" I need it to reach farther now.** A: Not that I know of. But, I bet you can go to your local hardware or builder store and find vinyl tubing that has a diameter that would snuggly fit over the end of the tube. Then you can make it how ever long you need and cut it to size. Bring the filter tube into the store and test it out on different sizes. I'm sure something will fit on it. **Q: I need an extension on the water intake, what is the longest length I can add to this filter?** A: I was concerned also when i realized how short the tube was, but can say after a years use that this is one of the best filters I've ever used in my 35 gal tank. **Q: Can I use this for a saltwater tank** A: Hey Daniel, Thanks for your question. Yes, you can use this filter for a saltwater tank. ## Customer Reviews ### ⭐⭐⭐ Very quiet - DIDN'T LAST *by A***S on Reviewed in Canada 🇨🇦 on 22 January 2020* EDIT - Almost one year later to the day and I have just had to purchase a new filter to replace this. As mentioned in my original review, this filter tends to stop on it's own more often than I'm used to after years of AquaClear use, and after discovering it stopped two days ago I haven't been able to keep it going. Turned back on for a day, then shut off again. Just tried cleaning/fixing now, and it turned on when plugged in but stopped again before it was even primed and running. As my first experience with this filter, I won't be buying again.I have purchased two of these Cascade HOB filters now in two different sizes. I am very much a die-hard AquaClear fan and have been for about 20 years, but the AC's have a very short overflow lip (where the water flows out of the filter into the tank). I have a fish tank in my living room and the AC overflow only reached the surface of the tank water if the tank was full absolutely all the way to the top - after a day or two of evaporation, the overflow on the filter was higher than the surface causing a waterfall that created more noise than I was willing to deal with in my living room. I went on the hunt for a filter that was equally as quiet but had a longer overflow lip, and after doing a lot of review reading, I took a chance on a Cascade. The filter is VERY quiet, so that alone makes me happy. The overflow lip is longer than an AquaClear, so it can go longer without being noisy and annoying before I have to top up the tank. So it met both my criteria. I dislike the media that the Cascade comes with itself, and the way it's set up, but thankfully it has a nice sized media box much like an AquaClear, so I just customized it and set it up like I would on an AC and it works perfectly. It does a great job of keeping the tank nice and clear. My only complaint is that in the few months I've been using the filters, I find that they clog and stop running pretty easily. There have been about 4 occasions in the last 6 months that I've discovered the filter not running - when I take it apart and clean out the motor and impeller, it starts back up again. Bit annoying after years of using ACs that basically run forever without clog issues. Overall, a great filter for the price, met the requirements I was looking for, and am happy with it. ### ⭐⭐ It worked well ... at first. *by A***R on Reviewed in Canada 🇨🇦 on 30 December 2020* I have many brands of aquarium filters (I have 13 tanks). This one worked well to start (all 3 that I purchased) but after a couple of months the filter flow became quite slow regardless of the speed it is set to - lucky to get a trickle. Separate it out, clean them fully, restart and it was ok for a few days prior to seeing the deficiency in how it works. ### ⭐ Trash product, no support *by J*** on Reviewed in Canada 🇨🇦 on 7 August 2021* UPDATE: absolutely no support. Find another productWorked wonders for a week was super quiet and then the pump got loud and water draw was cut by 3/4. Week two it died! No support at all!
