So I'm not exactly sure what happened, but it just seems like overnight I got this massive algae bloom. Everything was fine for weeks. My tank has been cycled, and is running for almost 3 months now. This happened on Sunday when I did my usual by weekly 25% water change. Then the next day I got those really thick cloud of green all throughout my tank.
I don't know if this would affect anything but I also change my foam sponge, my carbon pack, and my bio material. I am using to aqua clear 50 filters. Correct me if I'm wrong but I have heard that you should every month. I don't know if that had any effect to the algae bloom or not. I don't know whether running two filters is good. So any advice on that would be greatly appreciated.
Once I started to see the green algae bloom I did like I normally do, and just add a normal dose of API Algeafix. It didn't really seem to do much, so I decided to do some research. A lot of people said to do 25% water changes every day and black out my tank for about three days. Isn't that harmful for my fish or my plants?
On top of all that I have reason to believe that because of the API Algeafix... A few of my fish are dead. I'm just not sure at this point what to do I've also heard that in severe cases do a 90% water change and also black out the tank. But I'm a little bit skeptical... isn't changing out 90% of the water really bad for the environment and the tank? I know that my tank is cycled now, but even if so 90% seems like a lot. Also with me changing all of my filter media last week, I feel like that might be even worse for the environment. I'm just not sure if anybody could help me out with this I would greatly appreciate it!
