How I fought and won a battle against the dreaded algae bloom | 2021
A couple of months ago, I was very happy when a friend noticed how clear my aquaponics were. And it continued, until about a week later when I saw the first signs of green starting to appear. After a few days, the water was a solid green and my fish was only visible when I surfaced to eat. You are now in a full-scale battle against the algal bloom.
In nature, algae play a very important role. But in my aquarium, in addition to being unsightly, it can cause problems such as oxygen consumption and cause significant changes in the pH of the water. None of this is good for my fish.
There are many things I could have done to fight the algae. The first, of course, was trying to stop him in the first place. This particular tank is in my yard, and although it is partially shaded, it has been kept in full sunlight for a few hours a day. So I put up a beach umbrella for more shade. I also reduced the amount of food I was feeding the fish.
Another weapon I can use is an algicide. Many people have used it successfully. However, others end up with neither algae nor fish. I was not ready to take this opportunity.
A water change is also recommended, but I was trying to build up the nitrate and nutrients and didn’t want to dilute my tank with a big water change. I decided not to change the water.
My next option was to install a UV sterilizer. I had one fitted for a saltwater fish tank that I paid several hundred dollars for. It contained a powerful UV light that was designed not to kill algae, which it did, but to kill nasty creatures in the water that could make my fish sick. I didn’t need a light that strong or expensive for my aquarium.
I turned on my computer and logged into Amazon to find a UV filter that was less powerful and less expensive than the expensive saltwater sterilizer. No problem finding one on Amazon that was within my price range.
A few years ago, there was a game people played using the Google search engine. They tried to find a search term that returned only one result. It’s hard to find one, but it can be done. Today, you’re hard-pressed to find a term that doesn’t reach a million pages. Amazon is kind of like that. Try searching Amazon for a product and see if you can find one they don’t have.
You have chosen a strainer that has good reviews and is reasonably priced. Since I’m a Prime member of Amazon (who isn’t), two days later there were packages on my front door. I installed the filter right away and that was easy as it has thorns to fit many tube sizes. The instructions said it was easy to read the indicator light until you see the unit is on, but I really can’t tell if the light is on or off.
After a couple of days, I didn’t see any improvement and because I wasn’t sure the light was working, I informed Amazon that I was returning the unit and printed a return label. Amazon has a very liberal return policy. Next, I chose another UV filter and waited two days for it to arrive. Like a watch, it was delivered in two days. The old unit was installed for the two days since I decided to leave it plugged in until the new unit arrived.
Once the new unit arrived, I went to install it. But just as I was about to do this, I noticed my water started to ooze. So I left the first filter plugged in, and sure enough on day 3 the water showed more improvement. The same on the fourth, fifth and sixth days. By the seventh day, all the algae were gone. The filter was working although I can’t tell if the lamp is lit or not.
I kept the second filter as a spare and use it if the algae attacks another of my aquarium tanks. The catch is that you should take steps to prevent algae in the first place and be patient after installing something new. You won a battle against the algae, but the war was never over.
I don’t know if the filter I bought is the best or least expensive filter you can find, but it worked for me. If you have algae in any of your aquariums, you may want to consider installing a UV filter.
