Hello all,

Getting things set up for a new 45P Iwagumi style layout and I'd like to go pure UG on this one. There may be some detail plants like S. Repens or Hygro Chai but nothing that will make a big dent in nutrient uptake.

UG being a carnivorous plant causes me to hesitate about nutrient balances. I'll be injecting CO2 and running a Twinstar SM III on the tank, using Tropica powder type soil. If the plant mass is 80-90% UG is there even a need to fertilize? Is UG even known to absorb nutrients from the water column outside of CO2? Curious what your experiences with this plant have yielded and if anyone has run a high tech aquatic setup with only UG. Cheers,

Daniel

UG is only carnivorous in the sense that it can consume tiiiiiny critters. Not fish or shrimp.

You still have to fertilize it, as it's a plant. Even if you don't have to fertilize often. It tends to do best in bog or semi-aquatic setups. While it can grow well completely submerged, it will require regular thinning in order to keep it healthy. And I mean regular. I've grown it since about 2010 and don't recommend it as a carpeting plant for that reason. Best in small patches in areas that you can easily mess with without screwing up your tank.

Recommend growing it in a tank you aren't afraid of messing with or in a grow-out setup first. Just to get a feel for how it'll work for you. Even if you don't end up using it in your main tank, it will still be worth it. Nothing beats its flowing, undulating appearance in freshwater.
