Great product, may need more by ReefFiend

Experience Level: Intermediate

Posted on 10/19/2009 from INDIANAPOLIS, IN UNITED STATES

Comments: I always found the reviews with tank sizes vs. which powerhead to be the most useful, so I wanted to add one. I have a 2 in my 28 gallon bowfront and it may not be enough. I haven't moved my corals/anemone over yet, but it just feels a little weak in that size tank. I will be adding a small Rio from another tank that I am breaking down. That being said - it is a great, solid product. Yes, I would recommend this product to my friends.

Good Flow for a small pump! by rmulet

Experience Level: Intermediate

Posted on 10/12/2009 from BROOKLYN, NY UNITED STATES

Comments: I have a 15 gallon reef tank and I purchased two of these to replace a Maxi-Jet 600 that was pretty old. I love the way the corals now sway back and forth without using a wavemaker! I would get the larger size if you have anything larger than a 20 gallon and/or SPS corals. For my softies they are great though! I am really happy with my purchase. Yes, I would recommend this product to my friends.

Excellent product by TYLER MCKITTERICK

Experience Level: Intermediate

Posted on 10/7/2009 from LINCOLN, NE UNITED STATES

Comments: Never had experience with these before. Provides good flow. I purchased a nano and a "1" for my 20 long tank. Kind of wish I'd have gone with two "1"s. They produce much more flow. I should have listened to what others said, it's true. Go one higher than you think. They push a lot of water, but it's pushed over a wide area, so it's not overpowering. All-in-all, great product though Yes, I would recommend this product to my friends.

Off a submarine? by MATTHEW HILLS

Experience Level: Intermediate

Posted on 9/19/2009 from APO, AP UNITED STATES

Comments: This circulation pump is very powerful. In hindsight I would most likely have purchased the Koralia 2 instead of the 3; it just seems a little bit too much for my 80 gal. However, it is very easy to adjust, yet doesn't move on its own, it is very quite (assuming you put the end nozzle on securely), and is powerful enough to keep food from getting stuck in the inlet slots. All in all its great, just a little more powerful than I anticipated. Yes, I would recommend this product to my friends.

Hydor Koralia Nano - 29 G Tank by Shane A. Smith

Experience Level: Intermediate

Posted on 9/10/2009 from CAMERON PARK, CA UNITED STATES

Comments: I purchased the Nano as I had read somewhere that the Hydor 1 was about 5 inches long (which is not correct BTW - it is smaller than that). I figured that that size would be too intrusive in my 29 gallon freshwater planted tank and settled on the Nano instead. I had read in previous reviews here that the Nano barely moves any water at all but I figured it would suffice for the one side of my aquarium that wasn't getting good flow. One half of the tank gets good circulation from the HOB Filter so my intention was to install this on the other half where it was nearly stagnant in the hopes that this would help combat any problems with algae. Well, this little sucker is more powerful than anticipated!! It sucked the leaves of my large Amazon Sword up to the sides of the pump. So, I had to attach the Nano to the same side of the tank as the HOB Filter (the HOB is on the back, left-hand side of the tank and the Nano is on the left SIDE of the tank) and bounce the stream off the front of the aquarium to the back right-hand corner that lacked circulation. I watched a detached root that was laying on the substrate get stirred up off the substrate and then circulate repeatedly (in an elliptical circular pattern from upper left to lower right) throughout the whole tank for about 5 minutes before it finally got caught on the root of one of the plants in the back right-hand corner. It provided just enough flow for my needs and is more powerful than you would expect. Just for the record the HK 1 is not much bigger than the Nano - I saw it in person at a local retail fish store yesterday. If in doubt, go with the 1 rather than the Nano but I am very satisfied with the Nano, especially since it survived the "wife test" (she STILL hasn't noticed that it's in there - even after 2 weeks!!). Yes, I would recommend this product to my friends.

koralia nano circulation pump by TOM FITZGERALD

Experience Level: Intermediate

Posted on 8/3/2009 from NEWINGTON, CT UNITED STATES

Comments: I am currently using the koralia nano as an additional pump in my 12gal nanocube. I have set it low in the tank using the magnets to provide circulation "deeper" in the tank. It has improved water movement and lessens a stagnant bottom. For the money it is an outstanding circulation pump that I would highly recommend in nanotanks or larger. The pump also comes with a very good factory warranty should the pump fail. Yes, I would recommend this product to my friends.

Nano Pump by Jay R

Experience Level: Intermediate

Posted on 8/1/2009 from LA CANADA FLINTRIDGE, CA UNITE

Comments: I installed one of these in the upper front corners of my JBJ 28 gal nano and plugged them into my wave timer using a multiplier plug. This sync-ed the pumps with the return jets. They have significantly increased the overall circulation in my tank, and have a small visual impact. They are quiet, and produce a flow that is not overpowering for the nano. Yes, I would recommend this product to my friends.

surge filters by DANA

Experience Level: Expert

Posted on 7/31/2009 from HOT SPRINGS, AR UNITED STATES

Comments: Overall the product performs as advertized good flow and easy mounting... had to give it 4/5 because the manifold it comes with wont stay on without glue, and they rattle when starting up other than that they are silent. I will order the 1200 next time for a good Surge. Placement is crucial, took me a few days to get it rite but the suction/magnet made it easy, works like a charm..., they keep the debris suspended well so the overflow can grab it. For the money i guess i can put up with the clatter, it could be the used wavemaker i bought from a friend seems to work fine and the action i get from it is worth it... Great pump! Yes, I would recommend this product to my friends.

Comments: I've used various powerheads, but these have been the best so far that I've used. These have magnets and will not move or fall off unlike others I've used. I have two nanos and they work great in my 10 gallon tank. If you have anything bigger than a 10 gallon tank, think about the Koralia 1-4. These are small, efficient, and very quiet. One of the best pumps I've used, look so simple yet work so well. I will be buying more Koralia's in the future for tank upgrades. Yes, I would recommend this product to my friends.

Great powerhead by Nigthawk4211

Experience Level: Beginner

Posted on 5/7/2009 from SALT LAKE CITY, UT

Comments: I've been using a Koralia Nano pump for several months now, and just bought another. They are great powerheads; small, nice broad flow stream, reliable operation, no suction cups, and an affordable price. My one quibble is that it's a bit tricky to direct the flow because of the way it attaches to the magnet (you can't turn it too far or it'll fall off.) I've seen some of the larger versions of this pump in use at an LFS and they appear not to have this issue. Yes, I would recommend this product to my friends.

Wonderful by MEL

Experience Level: Intermediate

Posted on 4/28/2009 from HAVELOCK, NC UNITED STATES

Comments: This is the third hydor I have purchased in the past several years.....I feel that these items are a wonderful improvement for aquarists. The power they generate takes minimal wattage and allow a desired directed flow for corals in my aquarium They do not fall or slide out of place and are easily removed for cleaning. I still have all three.
