hey we know it all here. we get calls and email all the time from hobbyists mentioned about the coralife skimmer they had. in a way this is good meaning when they started this hobby, they start off slowly and build their way up. FYI, the two most common mistakes someone can make is when they get into this hobby. #1, They spent an arm and leg in a high end skimmer or high end product. A high end skimmer is never the way to go for a beginner in this hobby. Is like who own a Mercedes Benz for their first car, right? The down side of getting high end product is that it can risk the chance of killing the hobby for a consumer as they can get discouraged easily thinking the hobby is so darn expensive. #2, They go with a wrong brand. The down side of this is when buying a product from a brand that doesn't work, they alway have to keep on buying the product over and over again. This can be costly and will also discourage a consumer to leave the hobby. So it's very important when you find a brand that you can trust and just stick with it. As always good luck to your hobby.
