If you are facing problems with aquatic plants, but still need some plants in your aquarium then consider using some terrestrial plants with their roots in the water while their stem and leaves are in the air just above your tank, in my opinion this has many benefits:
I trimmed the plants, removed the gravel from the pot and started it from the beginning, you can check the new pond from this video
Ah and BTW I am not doing any filtration in this setup, I only use a small air pump and a couple of water heaters to make sure that the temperature don't become very low during winter nights
- It helps a lot in case you are not able to keep aquatic plants or they keep dying on you
- Terrestrial plants are very powerful in getting rid of excess nutrients, ammonia ... etc. and keeping for you a healthy tank
- It gives a very beautiful theme for the place
- A lot of these plants help in purifying the air as well
- You don't have to dose CO2, they will get it directly from the air
- Say good bye to algae
- Less maintenance and water changes to you tank
