Quiet low Cost Pump Works Great By Jeff on 6/6/2017Jeff would recommend this product to a friendVery quiet running, when it starts its a little loud but does not bother me. I will definitely buy more.
Great Inexpensive Pump By Rob on 3/28/2017Rob would recommend this product to a friendI have a 40 gallon reef tank. This pump in conjunction with another pump, and a Hydor Smart Wave pump controller, provides great variable flow to the tank. It could be a little quieter when it turns on and off, and it might wear out prematurely depending on the setting of the wave maker, but for the price I can afford it's decreased life span.
Koralia Evoluton Powerhead 850 gph- Hydor By Chuck on 10/7/2016Chuck would recommend this product to a friendI like the Koralia Powerheads. I have used several and have always had good luck.
Had three. All of them cracked near electric plug. By Russ K. on 6/5/2015Russ K. wouldn't recommend this product to a friendA little over a year ago I purchased three Hydor Evolution 600's. Every 6 months I clean them in vinegar. When cleaning them this time (third time), the sticker started to peel. I decided to remove the sticker altogether so it didn't flake into the tank. After removing the sticker, I found that there is a crack that developed from where the electric wire goes in, going outward. I was concerned and decided I'd replace it. Then I repeated removing the stickers on the other two units and found a crack in the same place. Due to the jaggedness and non-uniform direction, I am certain these are cracks and not a seem. Basically, my overall concern is that all three units cracked in the same place, and all are near the power cord.
I will say that I never got shocked or anything from them, but I don't want to take that risk for myself or my fish.
great value By kyle on 4/5/2015kyle would recommend this product to a friendVery quite. Suction cup works great. BRS pricing is way better than my LFS.
Very Good Pumps By Lake on 3/19/2015Lake would recommend this product to a friendThese pumps work really well. I have 2 850s. They run almost dead silent, turn on right away, and can move serious amounts of water. I would recommend these to anyone who doesn't want to spend a lot of money on controllable DC pumps like vortechs, but also wants very good quality from an AC pump.
good pump for the price By Bruce on 2/12/2015Bruce would recommend this product to a friendgood pump at a low cost. I have 7 of these in all sizes, use some for mixing salt but most just to create current in my tanks. Very little noise and have no had one fail yet. Have some turn on/off a couple times a day. They work good for that but I don't think it's the ideal unit for a wavemaker
Powerful By George on 1/28/2015George would recommend this product to a friendI love these pumps (1500gph) but was disappointed when i hooked them up to The WAVEMAKER they make clicking sounds everytime they turn on so i just run them on now.
Great pump for overall spread By Brien on 12/30/2014Brien would recommend this product to a friendGreat pumps, OK spread. Not a pinpoint shot so it is pretty gentle. Id buy again,
Great Pump By Lake on 12/7/2014Lake would recommend this product to a friendThese pumps circulate water and are perfect for any tank. Ultra quiet. Does not make a sound.
very good water movement By boxxmann on 12/3/2014boxxmann would recommend this product to a friendI purchased this power head as a replacement for my Seio that crapped out after about 6-7 years. The water displacement is broader and less direct than the Seio in my opinion, which I think is better for the overall current in a reef tank. Great product.
Quiet, affordable circulation pump By b-christopher on 10/5/2014b-christopher would recommend this product to a friendI can't speak for use with any wavemakers or timers, but for an always-on circulation pump the combination of power, quietness, affordability and durability are hard to match.
At these prices, they are attractive emergency backups as well.
