Hi again everyone,
I'm here with a very silly issue that is very common so I do apologize for the basic questions.
I have a 20gal tall planted aquarium and it is so green I can't see through it. It has been like this for a little more than a month I believe but it may be more than that.
I know for certain it is an algae bloom, as I've experienced this before and it looks super familiar.
I have been able to get rid of it in the past but I used chemical solutions and I really do want to try and avoid those if possible.
I use Aquarium Co-op's "Easy Green" All-in one fertilizer and gave around four pumps per week. I have been using it forever and it hasn't been causing me any problems (yet).
Could it being outdated be an issue? I dont have this issue in my other aquariums and I use the exact same fertilizer.
Maintenace and caring for my plants has been difficult as I need to empty out the tank halfway to even see from the top.
At first I thought I was overdosing on fertilizer, as I had probably been adding too much of it because my aquarium had high light and I wanted to be sure my plants wouldn't die due to lack of nutrients.
This seems like the obvious issue but I've been doing that for over a year and this has not brought up any problems, although it is fully possible that it is one now.
My aquariums had 10 hours of light a day and they're on a timer. Then I reduced it to 9 a few weeks ago and I just put it to 8 today and would love to not have to go under that but will if it is the solution.
My first course of action was to take the lights off for 3 days or so, and it did very little. For reference my aquariums are in a very dark room that never has natural light coming through except once a week when I do water changes and I need to see better. I highly doubt that is the issue however as I never do it with direct light and its only for max 2hrs.
I have done countless consistent water changes and it is a perfect fix if i want it gone for guests, but it sprouts back in two days.
My aquariums thus far have 0 animals in them. No shrimp, no snails, no fish, just plants and gravel.
With that in mind I didn't worry much as algae blooms don't really hurt plants as far as I know.
Then, I got motivated again because it was just ugly. I have an amazon sword growing in the back and I can't even see it. So, I got a bit impulsive and stopped fertilizing it altogether for about a week and a half. The water definitely slowly got clearer, but then my scarlet temples melted and died in the last two days. They were relatively new to the tank (maybe three weeks old) and had literally just started growing new leaves before melting.
I was sad of course and I also noticed slower growth in my other plants as well; my tiger lotus grew a new leaf, but it was a little yellower than the rest of the leaves. My previously fast-growing banana plant has yet to grow any more leaves and it's been a week since I removed the fertilizer. (Might write more on that later)
Now I potentially have a bigger issue.
Have I bombarded my plants with too much fertilizer? Are they so used to an excess of nutrients that they rely on it too much? In that case what should I do? Is that even possible for aquarium plants? I would love to be able to diagnose them better, but I can't see anything. I thought previously that my plants were growing at a normal rate, and the leaves weren't unusually big either.
Back when I first added my plants the aquarium gravel was new, and my dosage of fertilizer was the same. If anything, I was anticipating algae bloom back then, but it has been months since then and only now am I having issues. What puzzles me is what happened. I haven't changed a single parameter since the beginning, and the plants have gotten so much bigger since then that I figured they'd suck up all the excess nutrients.
If I knew the source I wouldn't be here but I know there's always something I'm missing.
I plan to slowly decrease the amount of fertilizer I'm adding in case that is the issue. Maybe I just did the wrong things at the wrong time? I am fully willing to redo anything I did listed above again if that is
the solution and I simply didn't do it right.
Anyways this isn't a pressing matter but I also would love for my aquarium to be visible sometime soon.
Thank you to anyone who can help, let me know if you have any question
Note: For Images below, the visibility on camera is a LOT better than irl for some reason.
