love the item, the flow is good and the magnet lets you place the item just about anywhere in your tank. I had one of these break and sent it in to Korali (Hydor) and they replaced it even without a receipt!
Ok so i bought the Koralia 400gph to create a stronger current in my 30 gallon freshwater fish tank and it works just fine. It does the job i want it to do and thats make a small current because i have some small danio’s (which love current btw) and i didnt want them to get sucked into it. Now the general rule of thumb for tanks is that you always go for a little more power than you need for anything but again becuase of my smaller fish i didnt. I have noticed though that even my 8″ bala shark swims against the current and seems to enjoy the small current so even big fish notice it but if you have decent size fish and have between a 30 – 45 gallon tank i suggest going for the 600gph Koralia.
thanks for not charging me an arm and a leg on shipping. Many vendors will not provide UPS ground service to Hawaii, even though UPS offers it. Good customer focus on helping keep my total cost down.
Pump is okay but not super powerful; I would probably get a 2 or 3 next time. this is in a 30 gallon SW tank.
Bought this product to help circulate water in my 55 gallon fish tank because a friend said the more you move the water the cleaner the water will look. After a week of use the product worked great. The clarity of my water increased two fold. The pump was extremely quiet sometimes I forgot it was on. The product was very easy to install also, the product uses magnets to install it to the side of your tank. I would recommend this product to everyone who wants to help clear their water in their fish tank.
nice flow. reliable. too big for small aquariums. It would be cool to have the same flow but with a smaller unit.
