We have been running a special on several of our overflows and want to make that pricing permanent. However, in order to do that we need to shrink the width of the overflows by a few inches to allow us to bring the shipping cost inline. Starting Monday (11/12/18), the size of the smaller boxes will go from 24" to 20", and the 35" will be 32". If you have your heart set on either the 24" or 35" and are on the fence, I would get your order in before Monday to get that size at the current sales price. Starting Monday (11/12/18) the overflow sizes and pricing will be: 20" Weir with 1" Drains - $179.95 (Silent Flow 1500+ GPH) 32" Weir with 1" Drains - $229.95 (Silent Flow 1500+ GPH) 32" Weir with 1.5" Drains - 249.95 (Silent Flow 3000+ GPH) We have also had many request for custom made boxes to fit the holes drilled for other manufacturers overflows to replace other boxes that are either broken, or more commonly, do not perform to expected standards. We have successfully made multiple boxes for hobbyist wanting to quiet up their previous overflows. The cost is the same as one of our boxes with our standard hole layout. Just PM me to tell me the size of overflow you want, and the overflow you are using currently. It just requires lowering the water level in the tank a few inches, unscrewing your old overflow and installing our new one. If done with a little fore thought you can be back up and running silently in very little time, without your tanks inhabitants even knowing.
