I have my pothos roots in the filter, or you could run an additional empty filter to put them in or some kind of basket.Thanks for your reply. I recently put a pothos plant on top of the aquarium. I don’t find the roots hanging in the aquarium very attractive so I was hoping to use an aquarium plant instead. I have been keeping a few Cherry Barbs in the tank just to get it to cycle. Are you suggesting that I put the pothos roots inside the filter? I’m using a rather small filter. Thanks.
If it's just a shrimp tank, I assume you're probably using a sponge filter? Load that bad boy up with duckweed! You can put a divider on top to keep it at once side of the tank if you want.
I assume she meant hang the pothos out the top of the HOB filter. That's what I do. Some people use a pump to pull water out of the tank and run it through a long flowerpot or something, then back into the tank, then the fill the flowerpot with plants that suck up nitrates.
I agree that once you quit dosing ammonia and only your shrimp is producing waste, your nitrate will stop getting so high.

It doesn't really matter what stage they remove nitrogen (ammonia, nitrates or nitrites) because removing any of them will affect the rate of nitrate formation. you just need something fast growing. Pothos works well, but only if it has a lot of light for fast growth. In my experience, building some denitrifiers into your tank works even better than plants. Though having both is recommended. add some lava rocks as decoration and some pumice stones in the filter. They have pores that are supposed to sustain the anaerobic bacteria that can turn nitrates into n gas. ive been experimenting with lava rocks and have had really good success. I have a 35 gallon goldfish pond outside with 2 fish and a lava rock substrate (home depot-sold for grills) and no filter - (some hornwort and wisteria and a bubbler) and after it cycled the water parameters have been perfect and stable ( about 1 month). I might actually remove some lava because my nitrates also crashed to 0 (along with the ammonia and nitrites) and I am shooting for 2-5ppm. I was surprised this worked because goldfish are way messier than shrimp.
You've lost a lot of shrimp in the past. Have you ever checked your KH and GH before? Also what temp is your tank? pH? Those 4 things are pretty important for shrimp from what I've researched in recently starting my own shrimp tank.
Wow It looks like your're doing great, water wise. I think with the recommendations in here for plants, and regular monitoring and water changes when necessary, you'll have great luck this time!
