I suppose the will take some nutrients from the water but if you like the setup then why worry. Just stick some tabs around the tank plants. I quite like the idea of using a HOB like a planted sump. You got me thinking now

Water isn't 100% nutrient filtered via an planted HOB. As long as there is an overflow and you're monitoring water/light parameters, adding food/micronutrients, & circulation your plants should be OK.

I'd love to see a picture!

I tried to fix your pictures, but it does not work.

You will have to save the picture, and the reupload to an image hosting website and not link directly from that forum.

I would not unplant the hob, but the answer to your question is yes. You did not mention if you have a high light, co2 set up, I am guessing no, because without supplementing, you will have problems. It also depends on fish load.

If you read walstads book, she repeatedly talks about the aerial advantage, that floaters and bog plants can more efficiently utilize nutrients since they can access co2. So yes they are using no3 and other nutrients. But it all depends on how your plants are doing. If the aquatic stuff is not thriving, you may need to assess what is in short supply, my guess would be nitrates.

it is a dirt bottom tank and i add liquid co2 alternative
ammonia and nitrate are at i would say 5 ppm the liquid test kit showed them as slightly darker then 0 but nowhere near 25

So what size is the tank? Why no pictures? Do not know about flickr and posting pics?

Wouldn't it be the same nute uptake if you had them in the tank?
