Aquarium Wave Maker Circulation Pump,360°Adjustable Ultra-silence Magnetic Mount Suction Submersible Powerhead Pump,2100PH Flow for Freshwater or Saltwater Fish Tank (15W 2100GPH)

Love the high water flow from this guy @ a super low price. Not all fish love the high water flow tho. Wish it had an adjustable flow rate. Magnet is super strong. Head stays where you point it (don’t overtighten). My Oscar’s, Plecos, & fast barbs love this blower. My silver dollars, red hooks, & Severums stay away from it so I point it @ the plants & they grow a little more before getting eaten. Audibly noisy but just a hum. Not bad for a fish room but I wouldn’t have it next to my tv.

Create a wonderful flow circulating , the tank i've had mine 43 years and never won issue. To anyone that buys this a good idea for you. Is to put your bubblestone right underneath it.So it sucks up the bubbles.Chop them up and wonderfully oxygenates the tank

The pump is quiet but not miracle of quiet. It arrived broken. Checking it closely, I can figure out how fragile the pump's neck is. No wonder why it got broken, its neck is very narrow and weak. Fortunately personnel of Amazon gave solution to my inconvenient.

This product is junk. Stopped working after less than a month of use. Turned it off to feed my fish and would not turn back on. Complete waste of money. Will not buy another one.

Love this wave maker. Primary use is to submerge in my RODI/Saltwater tub to circulate the salt mixture. My first lasted 4 years without ANY maintenance. Strong flow for 44 gallon tub

My Initial Review (1-Star): I was looking for a powerhead for a 32 gal reef aquarium. I opened this one and while walking to my aquarium to install it, I noticed it is covered in algae from pre-use (so it was used long enough for algae to grow on it before getting returned -- or they just sent be one they were using?!). After taking a picture of it, I thought I'd try it out anyway, to see how well it worked. While trying to get it in place and see the effect of the water flow, the cover came off easily (3-4 times) and my fingers got nicked by the blades. After eventually getting the powerhead to stay where I wanted it, I watched for corals to move in the additional water flow. There wasn't much movement at all, certainly no "wave" was produced. I reached in to feel the flow, barely perceptible. The power of this pump is quite lower than expected. Returning this purchase tomorrow. Additional Review (3-Star): I went to remove the powerhead and decided to mess with it. I unplugged it and plugged it back in several times. Sometimes, the powerhead seemed to work -- I can see the corals swish around from more water flow. After trying several times, it seems that the powerhead is *very* random wave sequence, where there is little to no wave motion, then maybe after 20-30 seconds there is stronger current that actually moves the corals. So the waves can be very long in between, low or higher, and very random rather than a more steady stream of waves. There is no way to control the strength or frequency of the waves.

For the most part, it is exactly what I was hoping for. Easy to use, powerful flow, quiet and and I love the magnetic back which makes it very easy to place and move to find the optimal flow for your tank. I am using it in a 20 gal. saltwater coral frag tank and I am very pleased. I would be even happier if the directional adjustment point was more ranged, but it would be at the cost of durability, so, I understand why it is somewhat limited in its ability to say, point directly downward. As it is, it will probably last longer and stay truer to its adjustment points longer with it's current design. Not complaining, just expressing my own wishful thinking. Hard to find effective blowers that have the range that I would like to see without them being less durable long term. I feel like this will last a good long while, and for the price range, I am very pleased with it. I plan to order another.

works

Es perfecta para un nano acuario d arrecife Yo la utilize para un cubo (nano reef) el flujo es perfecto Es un tamaño compacto

With in a weak it stoped working

Displaces a huge amount of water very quickly

Pésimo control de calidad, mataron mis peces e invertebrados, quien me los va a reponer? Su bomba tenía un cable suelto! Hoy la recibí y hoy mató mis peces

I do purchased this wave maker the big version 2100gph which is good quality but I return because too much strong so I purchase again the smaller version the 530gph and now I regret because first open this wave doesn't working, I need to spin the wheels to make it start then happy that already started but too much noise compared to the bigger versions.
