Frequently Asked Questions

How do you use an algae scraper?

It depends on the model you choose. If you go for a magnetic option, you will need to use the exterior piece to pull the inside magnet to areas where you want to clean. However, when you choose models with handles, you have to use the grip to direct the scrubbing pad to the exact spot you want to clean.

Will a razor blade scratch an aquarium glass?

Some algae scrapers feature blades at the end to help wipe off algae. While most razors work well, there are a few options that may scratch the glass of your fish tank. Also, these options may not work excellently for acrylic aquariums.

What causes algae on aquarium glass?

Algae growth doesn’t happen by magic. There have to be favorable conditions for algae to grow, just as with other plants. For instance, there have to be a source of nutrients, such as food leftovers and fish waste. Another requirement is light. Algae form as a result of a reaction between excess light and the available nutrients in the water.

How do you stop algae from growing?

Although there isn’t an effective way of utterly keeping algae at bay, there are measures you can take to slow down the growth rate. For instance, you can consider using floating plants like lilies and lotus. The idea here is to minimize direct sunlight. Alternatively, you can use submerged plants. These plants release oxygen into the water, reducing the amount of CO2.

How does toothpaste remove scratches from glass?

Before we proceed to give the steps, it’s worth knowing that toothpaste doesn’t work for deep scratches. For the tiny scratches, begin by cleaning the surface with a soft material. Apply toothpaste directly to the mark using wool or a soft cotton cloth.   Rub the area in a circular motion for about 30 seconds before you rinse with water. In case the scratch doesn’t go, repeat the process until it disappears.

Final Verdict

One of the struggles that every aquarist must deal with is getting rid of algae. No matter the measures you take to maintain the fish tank clean, algae will always find a spot in your tank. For this reason, every aquarist will need to have a decent algae scraper.

Unfortunately, picking the right tool from the cheap knockoffs seems to be another hurdle. However, with our suggestions, maintaining your fish tank clean is now easier than ever!
