Large Aquarium Tanks

In general: the primary excretory product of fishes and invertebrates is ammonia (whether theyre fed or not). Were it not to dilution by water change, chemical filtrants and/or biological filtration ammonia would accumulate to toxic concentrations.

As the story goes ammonia is converted to nitrites by way of microbes, notably by Nitrosomonas bacteria. Nitrites are in turn changed into nitrates by other microbes, especially Nitrobacters. This assortment of populations takes a while to establish itself

We want to take out livestock wastes, but add oxygen. We want to eliminate particulate matter by serving it out, but not our fishes! There are lots of ways to do these things; basically it comes down to how much time, money, general resource a person wants to put in versus the degree of cleanliness desired and required. The best available, most appropriate filtration system will get you the most trouble-free, low input of time and money in the long ru

I can get them easily through my largest wholesale account where I can get a delivery every week if I have the need. And, they are fairly inexpensive for me to purchase, so I can give my customers a fair price on a decent product and still make a healthy profit.

I make this point here because after all of my "impressions" columns, some of you may be wondering, "Why doesnt my local fish store carry that product?" Well, the answer is business. Most

These compact water pumps fulfill a variety of uses in aquarium keeping. They can be utilized to simulate the flow of tidal currents and waves in an artificial marine environment, or they can reproduce the rippling action of a river or

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

Hey
They are very interesting pictures that you have there. I am big fan of discuss fish, unfortunately there are no dealers who live .
