cracked head By Ted on 3/27/2017Ted would recommend this product to a friendI bought 2 of these pumps. I purchased one 3 years ago and another one, 1 year ago. One of them (I don't know which one it was since they look the same) recently stopped working. I looked at it and noticed a big crack in the housing. I don't use a waver maker with it and never dropped it. I'm not sure if I'll buy another one. I was always happy with it until it stopped working.
If you like shocks, try this out By Current leakage on 9/22/2016Current leakage wouldn't recommend this product to a friendI bought 2 of these 3 years ago for my 150 gal FOWLR. They worked well for 2 1/2 years until they began having startup issues. I didn't think anything of it except that they needed maintenance. It wasn't until I installed a grounding rod that I found a problem. My GFI kept tripping and I narrowed it down to a Hydor circulator. I unplugged it and removed it and I found 2 large cracks in the housing. These were obviously allowing water into the electrical pump and causing a current leak. A few days later I removed the other Hydor and found cracks in the same place! I have suddenly lost 2 dwarf lion fish in the past 6 months who were very healthy the day before, and I can't help but think that this may have been a contributing factor. I now have some Tunze pumps, hopefully they will work out better.
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.
great Powerhead By Devin on 9/10/2014Devin would recommend this product to a friendI use mine for a mixing powerhead, and it works great!!!! very good construction!!!
