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.

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.

Cobalt Fish Food Sold at PetSolutions

One of the newer fish foods offered by PetSolutions is the product line of Cobalt Foods. These products are manufactured in the USA and made in smaller batches to always ensure the potency of the added vitamins. Cobalt is one of the few foods that recognize that marine fish cannot convert PUFA’s (Polyunsaturated fatty acids) to HUFA’s (Highly unsaturated fatty acids) and that these important compounds must be included in the mix of the food.

What are UV Sterilizers?

UV sterilizers utilize a germicidal lamp emitting UV light inside of or over the top of a container with water. The water flows around/under the UV light and any bacteria or algae in the water will be killed by the exposure to the UV light. We use a measurement called a “kill dose” to determine if the UV will be strong enough to kill the organism we want killed. The kill dose relies on the wattage of the UV bulb, the flow rate of the water past the bulb, age of the bulb and the path the water takes.

Air Pump Aquarium Equipment

One piece of aquarium equipment that has seen the biggest decline in demand since the “golden age” of the 60-70’s is the air pump. Nearly all current air pumps use a rubber diaphragm and electromagnet swing arm to produce the movement of air. Older models used to use electric motors and a piston system, but these were noisy and required too much power and maintenance. Today’s air pumps have better types of plastic flappers and diaphragms and will generally perform for years between required maintenance. Most also require less than 10W of power to produce larger amounts of air.
