This is our all new Fleece Filter compatible 4 Chamber Sump/Refugium Pro baffle kit for 40 gallon breeder Aqueon® Glass Tanks. Tank and Fleece Filter Not Included. This 40 gallon kit is latest addition to our premium Pro Line of sump/refugium kits. The pro line offers unique features which give you exceptional control over your sump flow. Included are all the parts you’ll need to convert a standard glass Aqueon® brand 40 gallon breeder aquarium into a fully functioning 4 chamber sump or refugium for your display aquarium. All you’ll need is the glass aquarium, some aquarium safe silicone and a pair of filter socks that suits your filtration needs. The three included baffle plates can be used to divide the tank into distinct sections for a fleece filter, a zone for a refugium or equipment like protein skimmers or reactors, a bubble trap and your return pump. Choose the optional inlet plumbing guide plate to make connecting your plumbing clean and simple. Pro Line Kit Features. Precision CNC milled from premium grade black and clear 1/4 cast acrylic. Fully assembled and Weld-On® cemented joints so the kit is ready to silicone in the tank. Full height main baffle to distribute from your fleece filter to the downstream chambers. Adjustable water level baffle to provide a 5.5″ – 8″, 6.25″ – 10″, 7.5″ – 12″ running depth. Independent supports for supporting filter foam between the level adjustment baffle and the bubble trap baffle. Bubble trap plate to keep bubbles out of your return pump. Option inlet plumbing guide plate can be cut for one or two 1″ bulkheads (1.77″ hole) or three 1 schedule 40 PVC pipe passthroughs. Other options available upon special request. Baffle width: 17.45. Full height clear main baffle. 5.5″ – 8″, 6.25″ – 10″ or 7.5″ – 12″ adjustable third baffle with 1/8 slots for coarse water filtering and water depth adjustment. Two 1 filter plates which can go in between the secondary baffle and bubble trap plate. These units allow you to suspend filter foam between the two plates to trap bubbles and particles escaping the main refugium/equipment section. These are self supporting so the distance between the secondary baffle and the bubble trap plate is not defined by the width of the filter plate allowing you to set your place distance based on how much extra filter material you’ll need. Minimum distance is 1. If you are not 100% satisfied with this product you can return it within 30 days provided it has not been glued into a tank. Optional inlet plumbing guide plate. Using aquarium safe silicone, silicone the parts into your 40 gallon breeder glass tank and allow 24 hours to dry. NOTE: This is designed specifically for Aqueon® 40 gallon breeder glass aquariums. To measure the inside, use calipers or trim a dowel rod or rigid piece of cardboard until it fits between the front and back glass of the tank while parallel to the bottom. Message us with that length and we can confirm if it will fit. Custom kits made to your specifications are also available. No project is too big or too small. Proudly Made in the USA.
