What model and gph would be good for water changes? Basically, I have a 75/120/125/150g and plan on siphoning them via a flex line into a utility sink roughly 12-15' away. Any thoughts or suggestions?
I would get the biggest pump you can afford. I have an ecoplus and mag pump that I use for water changes. I have the ecoplus fitted to connect to a garden hose that I use for my larger tanks. I wish I would have spent an extra $30 bucks and got a pump that was larger.
Rio 32 HF. Can you handle the power is the real question. I have the same pump in my 2 220 gallon tanks for a circ pump it is rated at 1900 gph. Not to bad considering the overall size of the pump.
