Testing Out the New Eheim Power Algae Scraper

I placed the Eheim Power Algae Scraper base unit in the handle, turned it on, and started to push it straight down the glass, from the top to bottom. It powered its way through the algae in a single pass. I had to keep it at about a 30 degree angle, and it only seemed to work on a downward stroke, not when dragged “backward”. The blade pivots so you have a little margin of error as you press the blade against the glass. As I scraped away several week’s worth of algae, I could not help but be impressed with how well the Eheim Power Scraper was working.

What’s In a Name? Discussing Aquarium Fish Names

Right or wrong, certain names immediately bring certain expectations, whether the name refers to a fish, dog, cat, animal or human! There is something in the collective consciousness that associates a “look” or behavior with a name. Some fish rightly deserve their name, while others must suffer under the expectations that they cannot live up to. Below is a list of some of the most well known common name fish.

The Appeal of Arowanas

What is it that makes the Arowana so appealing to so many aquarium hobbyists? Is it:

  • Their shiny scaling and long, graceful fins?
  • Their expressive, large eyes?
  • Their sinuous swimming motion along the surface of the tank?
  • Their peaceful demeanor (unless they consider you food)?
  • Their ability to jump out of the water and snatch their prey from a low hanging branch?
  • Their variety of colors, available from silver to gold to red to blue/black?
  • Their ability to bring good luck and wealth to their owners?

It must be a combination of all of the above that helps explain the universal appeal of Arowanas!

The Common (or Not So Common) Plecostomus

Sooner or later, nearly all freshwater aquarium hobbyists will purchase one of the plecostomus species. This ubiquitous member of the catfish family is usually purchased to help control nuisance algae in the aquarium. Also known as a sucker-mouth catfish, the Plecostomus (Pleco for short) has the ability to flatten its mouth like a suction cup and use 100’s of small rasping teeth to scrape the algae off the rocks and even the glass of the aquarium.

Using Feeder Fish for the Pure Predator

Part of the beauty of aquarium keeping is learning about all the different habitats of the fish you can keep: where they come from, the types of water parameters they prefer, and their nutritional requirements. It is this last one that sometimes re-enforces the concept of the “survival of the fittest”. While the majority of fish kept by hobbyists can be fed prepared fish foods, there are some pure predators that must have live food

Using Aquarium Air Stones & Bubble Wands in Your Fish Tank

Ever since the early days of aquarium keeping, hobbyists have been using air pumps and air stones to introduce oxygen into the water. It may seem that the oxygen would enter via the multitude of air bubbles, but actually most of the oxygen enters at the surface of the aquarium water and the air stones help by bringing up a column of water with the bubbles and turning it over from the bottom to the top of the water. The air stones also help prevent stagnant areas from developing where the water may become oxygen deficient.
