Comments: I purchased the medium filter which has two baskets. It only comes with 5 bacteria media sstars so I purchased a media bag and added ceramic balls. I am running a HOB bio wheel filter untill the bio stuff in the API can takeover without the extra help. It is very quiet but I can still hear it operate. I am building acork lined box to reduce the(minute) noise even further. It was fairly easy to set up except for one annoying problem. I had a few questions so I called the customer supportnumber. What answered was arecording telling me to state my problem and someone would get back with me in a couple of days. I had to call Marine depot and check blogs. I am concerned about disturbing the bio bag when doing a service. I will try putting some tank water in a bowl with the media bag. I will update in a couple of weeks. Right now the tank is clear...ammonia and nitrates fluctuating.

Comments: Excellent product would buy again. I would get the best hose clamps that would be available locally. The plastic ones that come with the filter are not secure. There is no noise from the filter at all! The only reason for the 4 is that the hose clamps are iffy at best. I will buy this again for the rest of my tanks. I especially like the 4 tray filter options.

Comments: After careful consideration and research chose the Filstar XP. Have had 2 Marineland cannister pumps in the past that worked fairly well until recently. The second one developed a leaking problem after only about 2 years. Decided to choose another brand. Set up for the Filstar XP was simple. The instructions were well written. Parts came as advertised. Start up was a breeze. Pump is very quiet. Filtration for my 100 gallon fresh water tank is amazing. Water appears very clear after only 2 days. Water very clear before. Was surprised to notice a difference. Have had fish tank for about 25 years and Fistar welcome addition. Would recommend this cannister filter to anyone.

Comments: This works GREAT!! Got the 75 gallon unit for my Red Ear Sliders and it works well for keeping thier nasty tank clean. Ordered a second for the fish tank.. Only issue that keeps it from 5 stars is that it can be tough to prime. Ignore the directions, and put the pickup in the water. will save you a mess and lots of frustration.

Comments: The water leaks out at the electrical cord. The troubleshooting guid identifies the fix as the in n out water tubing must be putting too much pressure on the unit - but I keep trying to fix/adjust & nothing seems to work for more than a few hours. Anyone for water all over the floor? I didn't think so.

Comments: I replaced an Ehiem Proffessional 2 with this filter. The Ehiem ran flawlessly for 7 years but then started leaking between the base and the top. My plan was to buy the Ehiem Pro 3 2075 but after reading 30 or so poor reviews, I reconsidered. Apparently they also leak, brand new, right out of the box. I purchased the Rena Filstar xp3 for about $120 less then the Ehiem. The quality is not quite on par as everything seems just a little bit flimsier but the flow rate is 20gph stronger and it seems to work just fine. I leave the lower chamber clear so it can become a Filterfeeding Zone. The mid-chamber got my old Ehiem sponge plus a couple of the courser sponge filters that came with the Filstar. The top compartment holds 4 Chemi-Pure pouches with filter floss sandwiching them. All in all, this filter has adaquate capacity to function as I need it to on my 120 gallon reef tank. I only open it every 3 to 4 months, so I'm hoping that will help with the longevity of the latches and seal. This filter comes with all the media you need to get it up and running, although I don't use the the Bio-Chem Zorb as I don't find it to be on par with Chemi-Pure, and I don't use bio-balls of any type, but the media alone would come to a significant sum of money if you needed to purchase separately. The esthetics of the filter isn't great, but I keep it in the stand so it's no big deal. Also the filter runs silently, but so did my Ehiem, so no change there. I would recommend this to anyone who wants a compact, functionally well-designed, filter for a decent price.

Comments: We purchased the Rena FilStar xP3 for our 110 gallon freshwater cichlid tank. Setup was so simple. This filter is very easy to prime with no mess at all. The xP3 runs very, very quietly, almost silent. Our fish had been without filtration for 2 days, and the xP3 cleared their water up very quickly. We and our fish are very happy with this filter.

Comments: I highly recommend Rena Filstar canisters. They're sturdy, reliable and quiet with a large number of filter media possibilities. I have been using Filstar canisters for about 5 years. I have 3, an XP2 running my refugium on a 75G reef, an XP3 on a 45G planted fresh and an XP4 on a 150G fresh. I have never been anything but pleased with them. I have never had a microbubble problem from them and they have always operated very quietly. If you have a noisy one or are getting microbubbles then you are likely getting air in to the canister and should check all your O-rings and hose fittings. You should check them every time you clean it especially the large lid ring. My Filstars have been completely reliable for years and I have found them quite durable. Mine have been through the ringer a time or two and are still purring away.
