types of semi aquatic plants?

[AR1]

i am looking a few types of semi aquatic plants that would seriously suck some nitrates out of water and grow like weeds. The reason i am looking for semiaquatic plants is that i am tired of changing 300 gallons of water twice a week and setting up new filters. Also, semi aquatic plants have there leaves out of the water, making it impossible for pacu to take them as a snack

How will you stop the pacus from getting to the roots? Also pothos is a great plant for what you’re looking for.

i am planning on plants them in my bucket filter or in a secure area in the pond, surrounded by plastic fence netting. Thanks for the suggestion!

Water lettuce, water hyacinth

Grows fast and produces massive roots. Way better than pothos imo

They are good choices I do agree with you however they also require more a lot more surface area and if I remember correctly they require calmer waters, yes? If so then that would mean that chances might have to be made for them to survive and/or thrive.

I have used papyrus (umbrella palm), the root ball below is about the size of a basket ball.
The stems and leaves need to be above the surface, and roots work well below water.

Some other semi-aquatics I am using in my sump refugiuma are Mangrove trees, where roots are below water, with stems and leaves above the waters surface .

These were planted in sand filled lengths of hollow bamboo branches.
After about 2 years, the root systems are splitting the hollowed bamboo, but are are still in the tank.
I pulled them just for these photos to show, how they have grown.

thanks a million everyone, i will definitely look into these options.

one more question, they don't require any sort of fertilisers, do they?

Here's my effort,
Weeping Willow and Dwarf Papyrus

Brahmi (memory Herb), Water Spinach (Kang Kong) and English Water Cress.

No.
Adding Any fertilisers would defeat the object of them removing nutrients (nitrates) from the water.
