Freshwater Aquarium Jellyfish

Habitat: Require a specialized habitat which is very difficult to simulate.

Drugs: Often collected using Sodium Cyanide or drugs, or which come from areas of the world where these methods are still in use.

Aggressive: Extremely aggressive, have large territories in the wild, and are unsuitable for most community aquariums. Aggression in fish is not an indicator of "anger" but is due to highly-territorial behavior.

If youre unfamiliar with their operation, ask your dealer to take one of each out of their box, review their instructions and peruse their elements. Most all are magnetic-drive pump powered with few moving parts. The fluid-moving mechanisms and filter media replacement should be known to you in terms of cost of operation, repair and replacement. There is a huge difference in the same lines by different manufacturers between efficiencies for intended sizes and types of systems.

Flush valves are similarly constructed and have the important trait that their "ball" (the rotating piece that blocks water) does not fall out when the union is open...

They provide valuable circulation, surface agitation, and oxygenation in any aquatic exhibit. Without them our aquaria would be lifeless stagnant pools of water.

I have found these pumps to be some of the quietest and mos

This acted as a muffler of sorts, keeping the noise from the sucking air to a minimum. It also helped to keep the airline free from obstructions such as dust to reduce maintenance. The filter was a nice little plus, but it was not enough reason to recommend these pumps. It would be a nice to see this feature incorporated into other more reliable brands.
