Review: Works great, bought this product for multiple of my aquariums, fluval is great for most things, I prefer the Tidal filters as they are more durable and start on their own after a power outage, with fluval you have to help the flow to start the filter. However fluval makes great heaters I have multiple different wattage varieties as well for different size tanks and they all perform well!
