Fresh Water Aquarium Colored Rocks

The ebb and flow of the currents and the swaying action that they create has been a goal of many a fish keeper. That desire has led to ingenious Do-It-Yourself devices such as the Carlson Surge Device and the Toilet Flapper Valve Surge. However, these units, while effective at recreating powerful wave-like surges of water, also have there down sides. They are bulky, cumbersome, unsightly units that

This species is spotted on the posterior part of the body and to a lesser extent on other parts of the body.

Tropical gar, Atractosteus tropicus

Options for dcor in large aquaria are limited only by ones imagination. A wide variety of natural and synthetic materials can be used to construct attractive and effective habitats for the aquarium residents. Natural substrates like rock, gravel and s

To retain the structural integrity of the tank, and to provide for "welling" up of the water ahead of its flowing back and over the down spouts. If you find your overflows are so large that theyre draining too much water to allow for the water level height, or have so much water in play that your sump volume is being overwhelmed with the power turned off, you can add "street" elbows that you can "turn up" or on their side/at an angle to adjust water height and transit volume.
