Control nozzles will afford the final tuning needed in this regard. Most folks build their manifold the size of the inside perimeter of the display tank. For aquariums with a commercial plastic trim, small holes can be drilled in the recessed lip for plastic ties (cable/zip) to be fished through for securing the suspended manifold. Bare glass aquariums (no trim) can have fasteners (plastic hooks, cable ties, etc) embedded into a dab of silicone near the edge and put to use once the caulk is cured. Acrylic aquariums are very accommodating and can easily be drilled or glue More

.. by bushing up the lines here. 2) Practically speaking there is no "too large" overflow line size or number of overflows themselves. If you think 1" diameter through puts will do, go with 1 1/4" or even 1 1/2". Think you can get by with one overflow line of large/r diameter? Use at least two overflows... trust me here... as one is very likely, make that VERY likely to fail, get clogged, blocked by any number of circumstances, events. Systems of more than a hundred or so gallons should have at least three overflow lines... Ive seen very big tanks with numerous overflow lines More

.. is there sufficient space to get around, reach all? Im not just talking about the obvious gap/s behind, on the side/s of the main tank, but the entire three dimensional aspect of the entire arrangement. "Oh, I wont need to get behind, around XXXX once its all in place"... Ha haaaahhaaa, oh, youre killing me! Dont make the simple mistake of closing all the sumps, filters, pumps into too small an area... leave/make room to get to all... and I mean all of the plumbing, equipment such that you can rep More

Such devices are better suited for very large systems, like public displays. Wave-timers with powerheads are likewise inferior to dedicated pumps producing random turbulent flow as their staccato operation increases wear on pumps in use while robbing the system of potential water flow during "off" cycles. Truly, the closed loop manifold described herein produces some of the most efficient water movement in the aquarium while insuring a good value of use (pump life and More

Complimentary Goldfish
I've heard of people traveling with dogs, cats, and even an occasional fish. But this Chicago hotel takes vacationing with pets to a new level. They will provide a goldfish....

Mud sump
Hi, my husband is starting a new 170 gal tank with a 100 gal mud sump for me. Is it ok to take maybe a third of the mud from my 50 gal mud sump and use it like a sourdough starter? How long would it take for it to cycle? Thanks.

There are several species of shelldwellers in lake Tanganyika, but this one is definitely my favorite, Lamprologus ocellatus. Shelldwellers are maybe not .
