Aquarium Pharmaceuticals - Rena FilStar Canister Filters


I have the XP2 filter. It is as quiet as claimed, as easy to connect/disconnect, but my unit does not generate the flow claimed. I timed mine as being less than 200 gph. The unit is rated at 300 gph. Once I saw that the rotor was only 1/8" high, I knew this would have trouble generating throughput - which seems to be the case. It does appear to be able to generate the head (height of water column). I have tested the unit 3 ft below a water supply level. My normal tank setup is only around 2 ft between the supply lines and the top of the unit. I like the easy removable baskets, the shutoff valve assembly, and especially the quick acting levers for the head. The baskets are easily fillable with a wide variety of materials/substances. The XP2 comes with 2 stage coarse filter media, a Bio-Sorb pouch (ammonia and waste removal) and a rather thin fine filter media. Since I have plants, I removed the Bio-Sorb and had plenty of space to put filter floss. I consider this to be a good value for the money. If money were no object, I would probably go with the Eheim Pro series. The major pain of many canisters, including the XP2, is priming. The unit contains a "T" on the supply tube and they give a ridiculously small funnel to prime. The Eheim Pro's have built in primer - but at a much higher price. I have to say from a filtering perspective, I feel the XP series does as well as the Eheim and despite the design weaknesses, it is good value for money.

I've been running this filter for a couple months now and I like it very much. It is VERY easy to prime, the quick connect valves are incorporated into one lever, which is also a very nice feature. It appears that there is no bypass of the filter media in the water path. The price was very reasonable. Nitra-Zorb and the other related Zorbs can be purchased, designed specifically for this filter. Over all I'm very satisfied.

Well I have been using mine for two months, have to admit I like it! Does a great job. My XP3 might be little under the actual rated gpm of 350, I think the real value is closer to 300. Does do a great job at filtering, has lots of different media to use, and is easy to clean up. Has easy self priming, large filtration capacity, and can be used in both fresh water and salt water aquariums.

I recently set up a 125 g tank. Along with two Emperor 400's, I also included two XP3's. These are my 4th and 5th Filstar cannister that I am currently running. They are AWESOME! Very quiet, a snap to set-up, and even easier to maintain. For cannister cleaning, you simply unplug, stop the flow, lift the trays out, rinse and place them back. For a 350 gph rating (and I believe this as the flow is very strong) for under $100, you can not beat it! I have NEVER had a leak or function issue with them, and my oldest is over two years old.

I am extremely satisfied with these filters. I currently own a 125G tank and have two XP3 Filstars. I just bought a 55G and am looking into purchasing another XP3 due to my satisfaction. I have manufactured my own tubing to run the outflow water under the surface making my tank absolutely silent. I really like the different media I can put into the filter and cleaning is a breeze.

I've been using the Filstar Canister for 6 months now and the priming is darn easy. It's like a chia pet, "just add water". It is not as powerful as the others but priming saves lots of time. Overall it's a great Filter that cleans well mechanically, biologically, and chemically. Saves lots of time, and you don't have to get upset about the priming. Believe me, priming is the hardest part.
