Aquarium Algae can be a problem in an aquarium but with the correct advice and products, it can be easily solved. There are two types of algae or basic problems that you can have in your aquarium. The first one is if your aquarium water goes a light green colour. Then the second one is if the water stays clean and there is algae buildup on the glass, which can be green, or even black.
Firstly if you have the algae problem where the water is actually going green, the best way to solve this is use a chemical. The easiest way to determine whether your water is green is take a cup of water out of the aquarium and just look at the water and see whether it’s green. We have two types of algae, or algaecide that we can use to clean this problem up. Best way is to do a 1/3 water change, then add the chemicals. Two or three days later, you need to do another water change as the algae will start to die. It’s also recommended to clean your filter sponges as well because all the dead algae will clog the filter sponge.
Another way however it’s a little bit more expensive, from about $60 upwards, is to buy what’s called a UV sterilizer, Ultraviolet sterilizer. That way you run the water from your aquarium through the sterilizer back into the aquarium, and the sterilizer will kill all the algae spores and make your water go crystal clear.
Another issue with algae in your aquarium is where it builds up on the glass. There’s a couple of different ways to solve this issue. If you see the photo here, there’s plenty of different cleaning tools that you can use. Just get in your aquarium use your cleaning pads, cleaning sponges, and give your aquarium a good clean over. Remember, don’t use anything from the kitchen especially sponges from your kitchen as they contain chemicals and they will kill your fish.
Another way to reduce the algae build up on the glass is to choose your fish and choose some of the four species that you can see here. The first species is a sucking catfish. They’re vegetarian and they just swim around the aquarium, they suck onto the glass and they suck all the algae off the glass. There’s two different kinds. There’s the normal one and also a gold sucking catfish. This species here is a plecostomus catfish. They grow nice and huge, around 30 centimeters plus. You can buy juvenile plecostomus catfish and let them grow up with your aquarium. There’s also a bristlenose catfish. They come in different species and in different colours. Also, another fish is called the flying fox. They’re a great algae eater as well.
If you add a selection of one or all of these type of fish in the aquarium, it just means you will reduce your amount of cleaning that you have to do yourself.
Food also can be a major cause of algae in you aquarium. There are a lot of good quality fish food brands on the market, normally available from specialized aquarium stores. These type of foods have low ash and low phosphate. One of the big causes of algae is phosphate, so throw out your cans of fish food that you got from the supermarket. Most of the brands are high in phosphate and can cause a lot of algae in your aquarium.
Another way you can reduce the chance of algae growing in your aquarium is to put in a phosphate remover. As you can see, here’s one brand of phosphate remover, which is a combination of volcanic rock and peat. They absorb phosphates in your aquarium. Phosphates is one of the major causes of algae.
Algae is a plant, and plants require light to grow. To reduce the chance of algae or reduce the growth, we recommend you put your light onto a timer. Go to Bunnings and get a cheap timer for about $10, connect that up to the light, put it on a setting, maybe eight hours a day should be adequate, and that will reduce the chance of algae growth.
When you adjust your pH in your aquarium, there are products that have higher phosphate levels. For example, pH Up has quite a bit of phosphate. Using that type of product is an easy way to put the pH up, but will help, or will increase the chance of getting algae in your aquarium. We have other types of pH boosters which are called KH boosters. They have less phosphates, or nearly no phosphates, and there’s less chance of algae if you use these type of products.
