Saltwater Aquarium Test Kits

This is more important in saltwater tanks, where the high density of the water greatly reduces the amount of available oxygen.

The size of the nitrifying bacteria population in the biological filter determines how much toxic ammonia (fish waste) can be processed. If there are too many fish in an established aquarium, tests for ammonia or nitrite will be positive. The beneficial bacteria pop

Air Pumps and Paraphernalia:

These are a source of pressurized air for operating undergravel air lifts, air diffusers (aka "stones"), and air-driven foam fractionators. There are several varieties, the most common/popular are the lines of "diaphragm" type air pumps. These are simple, solid designs that are (hopefully) quiet, consume little energy and are easy to service. The pump must be located higher than water level or employ a suitable back-flow preventer (check-valve) to prevent water capillating, draining out in the event of power or air-pump failure.

Air-line tubing is the 3/16"

Proper care of this beautiful fish is not any different than any other tropical fish and they can be a lovely addition to your tank. With good care, proper feeding and maybe some luck, your Siamese fighting fish can live up to 3 years.

..). They have flat faces with o-rings that allow you to simply thread apart a connection (or two) and remove the part (like the pump). Flush valves are similarly constructed and have the important trait that their "ball" (the rotating piece that blocks water) does not fall out when the union is open... Look around (the Net, hardware and larger LFS stores) and you will find examples of both

for wet-dry filters). These towers employ a media and circulation in an attempt to optimize filter surface area, and per-unit circulation/conversion efficiency. They work; and are especially useful in Large, crowded (as in wholesale) systems with widely vacillating bio-loads.

Other filters focus on the removal of the "end-product" of crowded closed marine systems, nitrates. Macro-algae and other nitrate-using live-rock constituents can only do so much in using up this hotly-debated metabolite. Algal scrubbers of different sorts, with intense light, shallow water and specialized attachment media can do amazing amounts of nitrate (e
