Goldfish Aquarium Scrensaver

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

Enough of this Introduction to Economic Theory; lets get back to talking about fish and fish products! As I said before, I sell and use more Hagen powerheads that any other brand. If I am dealing with a freshwater setup, I use Hagens. On the other hand, if this is a saltwater installation, I give a slight edge to Aquarium Systems Maxi-Jets because they use a ceramic impeller shaft which are more durable in salt water than Hagens stainl

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

Here is a brief roundup of the commonly available powerheads found in the aquarium hobby.

Aquarium Systems Maxi-Jets

The Maxi-Jet powerhead on the left is being used to power a small protein skimmer. The attachment on the inlet allows air to be drawn in through the impeller, producing very fine bubbles.

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

Where to place my Zoa's??
I was wondering how much light most Zoa's need. I am thinking of putting the new frags lower in the tank, right on the sand bed or just a little above.
