As the water cools, pond fish require less protein in their diet. When koi and goldfish are fed high-protein food in cool water, the excess protein is excreted as ammonia from the gills. The microscopic organisms that make up the biological filter (and consume ammonia) als

The two parts are usually connected using nylon bolts and nuts. On most models, water overflows into the waterfall cup from the water surface in the aquarium. A siphon tube delivers water from the waterfall cup inside the tank, over the side of the aquarium, and into the prefilter box. The water then passes through a sponge prefilter element, and feeds via gravity, into the filter below the aquarium. Some hang-on prefilters are of the "continuous-siphon" type. These prefilters actually have a built-in channel which allows the water to travel over the side of the tank without us

The creation of this list was not based on any type of scientific method, but rather on our own experience with the many aquariums weve installed. Each species on this list, has consistently proven able to tolerate high levels of ammonia and nitrite, for at least six weeks, in hundreds of saltwater aquariums installed by The Aquarium Professionals Group. We have had success with each of the listed species on at least fifty separate occasions, and with some species, many more.

It is important to note, that we h

The screen is then covered by 2" of fine coral gravel. This allows the aquarist to turn over the top inch of gravel occasionally to clean it, without disturbing the anaerobic layer below.

Anaerobic bacteria form in the bottom depths of the substrate and in the water below. As anaerobic bacteria cultivate, they remove nitrates. Anaerobic action produces a fair amount of heat. The heat warms the water layer below the gravel. The warmer water flows upwards, displacing cooler water above the gravel. This action moves water through the plenum at very slow rates. The slow movement of water through the gravel helps to prevent dangerou

This technique is not appropriate for most retailers who are better off recirculating, mixing system water.

How it Works:

Each tank or tub on a system is drilled and fitted with an overflow through the back or a bottom standpipe. Acrylic aquaria are easily drilled wit

Id say a dark room, no flash, and a wide aperture. Try using different camera speeds if you h.
