## Description

If you&apos;ve been keeping a Reef Aquarium for a while now, this HAS happened to you! You come home from a long day at work and relax in front of your tank only to find that you cannot see that Blenny or other fish ANYWHERE! That fish jumped in the OVERFLOW! ARGH! Or how about this... You get home and there&apos;s water everywhere! A big snail crawled into the overflow and is stuck in the pipe causing a backup! Got algae growing wildly in the hard to clean overflow box? These problems all go away when you install our Cornerflo Covers! These 100% ABS black plastic covers are designed to go over the corner overflow boxes for Marineland and Perfecto glass aquariums. They are CNC routed out of 3/16&quot; ABS and designed to fit perfectly over the covers. To install, just use a dab of super glue (just a dab will do!) on the overflow box and fit the cover in place and hold for a few seconds. This way it is easy to remove without damaging the box when and if you need to! The small kit fits dual Cornerflo Aquariums up to 90 gallons. For larger aquariums, be sure to purchase the Large kit. You can use the Large kit for smaller aquariums, but the cover will overhang the box by about 1&quot;. This is not all bad though, as it will shade the intake grate of the Cornerflo Overflow box just enough to prevent algae and coralline growth on the intake reducing water flow. These are a must have for any serious reefer. Not only do they offer the above benefits, but they also help muffle the water sounds inside of the overflow. They don&apos;t go away, but sure do get quieter! Pick up a pair today and stop worrying about the stranded fish or the major hair algae bloom inside the overflows!

## Features

- Cover your Cornerflow Corner Overflow Box for your Marineland or Perfecto Aquarium
- Keep Unwanted Fish and Snails OUT of your Overflow Box!
- Prevent Algae Growth Inside Overflow Box and on Intake
- Black ABS Plastic CNC Machine Cut for Perfect Fit
- Reduce Cornerflo Water Noise
