I figured i would need alot more. The plants i added grew about a foot in one week which shows they are deff eating nitrates but nothing noticeable enough for me to keep them. I dont have enough room in my sumps for more then 1 plant either.

My pothos doesn't look like they are growing any...leaves are kinda curled up a tad.
I tried a plant in each one of my 450 gallon ray tanks. Im seeing no difference in nitrates so i will be pulling them out. Maybe for my bioload i would need like 10 plants in each tank to see a difference...

How do you know if your pothos are taking to the tank water? The roots on mine is a bit darker then when I pulled it from the flower pot.

I tried a bunch in my ray setup and didn't notice anything. Rays just seem to produce nitrates naturally. Mine also grew like crazy but overall were more of a mess and not worth it as they didn't seem to do anything.

Rays are heavy eaters whom produce a large bio load, when you compare the efficiency of plant filtration vs a drip system/large & frequent water changes in a aquarium there isn't much of a comparison unless you want 4-6 plants with added lighting! You would need adequate room for the roots plus room for the actual plant so when were talking 400+gals with a large bio load realistically speaking unless your very into plants and love the look it's not the most effective option!
But keeping 1-2 plants after some time will help water quality plus help filter the surrounding air amongst other benefits. But pothos are never going to replace the efficiency of a drip system on such large tanks with big fish!
The information Dr SL provided and has given in the past puts it into perspective, that's some good research and statistics, sincerely appreciate your efforts!
If you imagine 4 adult Oscars in a 55gal pothos are only going to make a knick in the overall bio load, which we can assume with daily feedings is 120-150ppm per week but if the plant eats 30ppm n03 in a week that's a 20% or so decrease. Obviously this is a harsh example
