Do Substrate Fert Tabs Feed Plants Above The Gravel?

yep hygro ploysperma, hygro poly rosanervig, ludwigia repens, rotala rotundifolia etc. all super fast growers.

But with very low light? I have a 30gallon tank with only a single 15w T8 bulb (1/2wpg)

The LFS where I purchased had them labeled as "Water Sprites", but they didn't have the official name posted - so I'm not 100% that they are Ceratopteris Thalictroides. But they looked similar to me! I'll post a before and after pic a bit later to show you the change in growth in 5 days...

Would that be PetSmart? I saw some there too.

Its not a question of light. We are talking comparisons.

Therefore under low light the super fast growers grow much slower than under higher light.

What I am saying though is yes you have low light but you will still see these 'super fast growers' outpace the other plants.

They sitll grow faster than the other plants. Just not as fast as they would with much higher light and presurised CO2

No - it was an independent in Charlotte, NC.

For you curious types, here is the tank as it looked the day I planted the water sprites, five days ago (and with the old light bulb):

And here is a picture from today. I drew red lines to estimate the level of growth based on the first picture:

So this plant type does well with my .60 WPG.
