Crak Marine Aquarium 2

Some hobbyists have accumulated enough prefilters and filter bags to rotate in a new one several times a week, or even daily. Trust me on this-if you replace your mechanical media on a frequent basis, you will see a very noticeable improvement in water quality and a measurable reduction in nitrate and phosphate acc

If I am correct, then if you dont like the idea of your top strut bowing (it is a bit disconcerting the first time you notice it), then use thicker acrylic. The less the front pane bows, the less the top strut will bow.

I couldnt figure out why my tank had cracked where it did (see picture earlier) until I noticed this upward bow on the

This is very difficult to achieve in practice, as such an aquarium will have very few fish, and that is not satisfying to most aquarium hobbyists. To control the nitrate levels in an aquarium, we do water changes. That is why water changes are so important. They lower nitrate levels before they get too high and become a hazard to fish.

Fish Out of Water
Although Boni Comandante Jr.’s technique is intended to ship fish used for food, the idea of putting fish to 'sleep' and then transporting them without water is an interesting one.....

Mud sump

I on the other hand don't have that luxury and turn on my tank whenever I get up turn it off when I go to bed. I there a problem with the inconsistency or is it just not.

Common Cichlid Diseases
Like all fish kept in tanks, Cichlids are prone to disease. The artificial environment and closed system are the perfect breeding grounds for pathogens and parasites. Of course, wild fish get diseases, but these go unseen by everyone but fishermen and wildlife biologists. The best cure is always ....
