I Recently Purchased a Marineland 400 filter from Chris on July 30 2015 The filter is so noisy it interferes with watching TV. My dogs are constantly barking at my filter. The spray bar every couple of second emits a pulse of water through the spray at which time a very loud gurgling noise is emitted. Marineland gives a number to contact them before returning item to the store. I tried the email 3 times Marineland never responded. I will be returning this filter to Chris as soon as I am on his side of town. I caution everyone to be aware that Marineland has a problem with their filter and the service is non existant.
