Visitherm Aquarium Heater

Often seen in tiny little bowls in the pet store, this male of this species is fiercely territorial and must be kept in separate bowls or aquariums or they may fight to the death.

These interesting fish are equipped with a tipped up mouth that enables them to get air from the surface of the water and, therefore live in small bowls or those plant vases t

The plenum method was discovered by Dr. Jean Jaubert and is often referred to as the Jaubert System. "Plenum" refers to an un-oxygenated layer of water trapped beneath a deep layer of gravel or sand at the bottom of an aquarium. This layer of water becomes anaerobic. Bacteria cultivate in this oxygen-free environment and remove nitrates from the aquarium. There are several variations of the plenum, depending on what literature you read.

The basic structure of the plenum system is essentially a deep (3" to 4") layer of gravel, suspended 1/2" to 1" above the bottom of an aquarium. It is usually recommended that very little

It is especially unfair to these fish, who eventually join the ranks of millions that have died needlessly, their bodies decomposing in our dumps and landfills, when just a few short weeks or months before, they had been thriving in the ocean. Are we trying to make you feel bad? No! We are simply trying to open your eyes to one of the darker sides of the hobby we all enjoy.

However, in contrast to a standard multi-strip, only three of the plugs have power 24/7. The other three plugs are connected to a controller knob and turn on and off in an alternating pattern. Plug #1 runs for a set period of time and then shuts off. When #1 turns off, #2 turns on and runs for the same set period of time. So, #1 and #2 are always opposite of one another. The #3 plug is a little different. It will turn on and remain on all the while #1 and #2 operates for one cycl

It may well be necessary.

PVC (Poly Vinyl Chloride) pipe is the material of choice, generally "Schedule 40" (rated for up to 400 psi pressure), though there are clear plastics (that wont stay so...), ABS, even advocates of flexible tubing... For practical purposes, un
