Review on Syncra Multi Purpose Designed Freshwater Saltwater by Melissa Jones

Excellent Pump. It's very quiet and powerful for its size! I use it in a Fluval Evo13.5 tank and it's probably too strong. To be honest the .5 is probably a better fit, but I like the extra power. Note to Evo owners where this pump is making noise. I've found that standard Lochline outlets restrict flow and create "back pressure" at the pump, causing noise. By using higher flow outlets or removing small outlets, the noise is eliminated and it is nearly silent.
