SUNSUN JVP Series Submersible Circulation Powerhead Pump (530GPH, 2-pack)

Worst worst worst Product to buy, don’t buy this it stopped working in 30 mins and I had waited for its delivery for over 5 weeks in mumbai India and when it arrives it stops working very disappointed u get the same stuff little cheaper in local market thought the quality will be better than local products but it’s just waste of my time and energy

These wave makers are well worth the money.

These are nice little powerheads. I have had no issues with them at all as so far. I thought they were going to be more like a wave maker but they move the water around quite well, lots of thrust for these things. I like the fact they can swivel around and I can point them where I want. The suction cups work nicely and the additional "push tab lock" really locks them down. I would give them 4 stars because there is nothing to decrease the rate of flow but if was that big a deal I would have bought some that did. I do however take a flimsey little plastic cup and cut a hole in the end(bottom) and place the cup over the heads so the cup kinda of covers the intake holes and reduces water flow if I have a wandering or floating anemone so it won't become diced 'nem. Works great. Not enough restriction to damper/harm the impeller/head but just enough to kick down the water movement and not suck in stuff. I have also cut thin slits in some cups when I want a little more water draw. You could mod it anyway you like, I tend to pop a small hole in the rim of the cup, fasten it to a seperate suction cup and lock it down so it won't blow off. :)

Does make a tiny bit of noise, and can feel the vibration in the cord

Weak, but works for what I wanted. I put one in a 10 gallon. It's ok, but a little weak. Using the other for mixing salt water. Works great for that.February '24 - update - both crapped out. They had occasionally reversed directions, but I had been able to stop the propeller and it'd be fine, but suddenly neither one will work properly. Still good for the price, but you do get what you pay for.

First off, no matter what product you buy it seems at least a few people have bad experiences.The truth is it’s inevitable that something will go wrong especially when you can buy 2 of these fans for $15But I must say I just installed one of them and it was easy.It makes no sound.It pushes water very well.It is small so it doesn’t take a lot of space in my 75 gallon tank.The suction cup is very good.So will there be defective units? I’m sure.Will a device die before you want it to? Possibly.But I have no regrets purchasing this circulation fan.It does exactly what it says it will do and hey, a 2 for 15 deal means I have a spare in case one does go out.For those thinking 1 isn’t enough for 75 gallons it all depends on how much flow you really want. This thing pushes water very well. I also have an fx6 for filtration which does move water pretty good but the fan really added that extra flow I needed.My guppies love it as they swim in front of it to get blown black and do it over again.All my fish are much more active since installing and at night they find places where the current isn’t strong so I just leave it on.Do yourself a favor, don’t fret about reviews and give it a try. It’s only $15.
