Jenks Aquarium

The breeding aquarium should be 80 cm in length or larger, with some suspended and anchored plants. The aquarium should be filled with about 15-20cm of water with no air or filtration, temperature 29C. Up to 2000 eggs can be laid in one spawning. When the fry become free swimming the male should be removed from the aquarium. The female should be removed right after spawning.

The

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

These filter types still rank high as "bacteria homes" for newly-overcrowded systems and quarantine/hospital tanks. They weather changes (such as moving) and wont change your water chemistry during treatments.

Power Filters:

Hang on the back, inside the tank, pressurized and not canister models are all good ideas. In addition to speeding and stabilizing "cycling", these workhorses are great mechanical filters and water circulators. They

Please thoroughly cleanse these items and gravel now, before putting them into the system.

Unplug everything, drain the system down, and carefully place the substrate over the sub-gravel filter (if youre using them) and the rest of you CC (chemically-correct) decor.

Have you set up a "mixing tank" for blending synthetic seawater? This is better than just pouring it into a bucket and trying to "make it on the run". Dont mix it in the system.

Whether youre using natural or fabricated saltwater, this is

Nitrification occurs principally through bacteria (e.g. Nitrosomonas) metabolizing ammonia to nitrites (NO2-) and other groups (e.g. Nitrobacter) in turn converting nitrites to nitrates (NO3-). Lets look at this in another way (refer to Figure 3); an "idealized" time line for establishing nitrogen cycling in a new marine aquarium:

At mark "0" youve just set up your system and placed all new (read that as sterile) marine water (synthetic). In most cases, the hobbyist will shortly thereafter ("1") introduce either A) Some hardy (nitrogenous waste resistant) fishes, such as damsels to help "pop" t

Daphnia For The Aquarium

Daphnia are a great food source for both young and adult aquarium fish, you could catch them with a net in a pond, but their's a risk of bringing in parasites. I just found an article about growing daphnia yourself, nice read for the real tinkers out there :-)
