Sticking a couple of quarters under one corner of the tank to level it means you are concentrating much of that one ton on a small part of the bottom of your tank and it will certainly crack.

You can shim a tank between tank and stand but you must be very careful in order to avoid unnecessary stress on your tank bottom. Therefore, this is generally not recommended unless you are good at making large perfect wedges.

It is better to level you tank by shimming underneath the stand. Here again, you need to avoid concentrating one ton in just a few

Almost all public aquaria utilize ozone with theirs; you should to. The chemical degradation of large organic molecules, responsible for off-color, turbidity, low oxygen and some toxicities by ozone make its small start-up and operational costs pale. If youre even vaguely considering an investment in any sort of meter, doser, denitrator, ultraviolet sterilizer... STOP, do not proceed to go; buy and use a small ozonizer in conjunction with your skimmer first. Almost all public aquaria utilize ozone with theirs; you should to.

Ultraviolet Sterilizers: Use in Filtration Systems

Ultraviolet (U.V.) radiation is sometimes employed in water p

Now the question arises, why dont all aspirating skimmers use needle-wheels or perform similarly? The answer is needle-wheels are a patented technology. It costs real money to license and produce this kind of hardware. The higher end skimmers of this style are very effective, easy to adjust, easy to clean, and moderately sized (modest spatially).

Advantages to Aspirating skimmers:

Top shelf models are categorically consistent and reliable (bubble size, skimmate production, etc.)

Lower maintenance and no significant expense of upkeep (no air stones or pump diaphragms)

Most occupy comparatively less

Scratched Glass
Most of us have run into this problem at one time or another. Care to share your experience with scratched glass? "Does any one know how to fill some scratches....

phosphates too high
hello again- Well my 90 gallon predator/reef tank has been up in running for about 7 months. Everything is running smoothly so far- water parameters are nitrate > 20 ppm, nitrite 0ppm, ammonia 0 ppm, pH 8.2, salinity 1.025, but phosphate.

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 .
