Here's another awesome custom build. This one makes great use of the extra real estate in a Marineland 125 gallon tank. Inlet water is fed in from both ends with the return chamber in the middle of the tank. One side is the refugium chamber, the other side is for equipment. Both sides feature dual 7" filter socks, a full width blind interlocking sock baffle for easy assembly and they have independent water level adjustment.

Here's a nice example of a custom build. The customer had a non-standard glass display tank which he repurposed as a sump. Based off his measurements we made a custom intake baffle, adjustable weir/depth baffle, a bubble trap with media supports, and custom inlet and return section lids. Some unique features to this build include the use of 1/2" acrylic for some of the baffles to minimize bowing (it's a 23" wide tank), blind drilled and tapped holes for the media support plate, recessed bulkhead holes in the lid so they sit flush, lid reinforcements to minimize bowing and a custom mounting setup for a Neptune Systems liquid level sensor. Finally, the bubble trap section has a custom lid system to prevent salt creep as the water passes through it.

We're starting to produce our new ultimate kits for converting Aqueon glass aquariums into sumps and refugiums. These kits utilize a new integrated sealing system into the lid assembly which seals the inlet pipes without the need for huge bulkheads. This allows us to keep salt creep to a minimum while maintaining a small footprint for the inlet section of the tank. While these will work with any standard 1" PVC pipe, we are including special cut down pipes and 1" slip/slip couplers so everything you need except the tank, silicone and filter socks you'll need to get this up and running is in the box.

Available now in 4 chamber or 5 chamber configurations for 20 gallon long tanks. Other sizes coming soon or up request.

Tank dividers are now available. Made from 1/4" cast acrylic our dividers are available in three styles:
1.) Silicone in - these dividers are installed using aquarium safe silicone (not included). This installation method provides a semi-permanent fixed position divider which your tank inhabitants can't move. It also provides sealed edges so even the tiniest critters can get past it.
2.) Suction Cup install - these dividers include four dual suction cup brackets which allow the the divider to be quickly and securely installed in your tank. They also allow the baffle to be easily removed or moved whenever you want to change up your tank layout.
3.) No Suction Cups - the dividers have a slot in the top which accepts the lip of the tank rim. Once installed, the tank rim lip supports the divider and allows it to be moved or removed as you see fit.

All dividers are available in black or clear acrylic with or without diffusion holes.

Standard size and custom overflow boxes are now available. These boxes feature our unique 90 degree edge back cuts which allow us to form tight, smooth and uniform 90 degree edges along the front vertical edges of the boxes. The front and sides of the box are formed from a single piece of acrylic so those vertical edges can never leak. The bottoms use recessed joints to provided added surface area for strength and a leak free joint. The lids are also recessed and include 1/8" air holes for minimal noise during operation. Finally, each slot has an internal bottom bevel to guide the water quietly into the overflow box. You can choose from standard sizes or we can custom make them to fit your needs for specific dimensions and or flow rates.

Custom design services.. Here's an example of a custom designed raceway style sump kit for a 29 gallon tank. This design provides for two water paths allowing you to control the depth in the refugium section while providing a low flow environment for the critters living in there. After the refugium, there are two media chambers for mechanical and chemical filtration before the water enters the return pump section.

Design services like this are provided at no charge assuming you purchase the kit from us. We are vertically integrated, with design and manufacturing all under one roof so lead times can be as short as 1 business day. If you have needs for a custom sump design please contact me, we'd love to work with you to make your project a reality.
