Thanks!Hi folks! I apologize I did not post that image with the instructions again. I link it below.
The grō soil tabs function like a thin topsoil underlayer, providing a slow release source of nutrients for plant roots. Unlike regular topsoil, you can add grō soil tabs to your established tank. Just push them down into the gravel substrate until they rest on the bottom glass pane. Make sure they are well-covered with gravel and avoid disturbing after placement. Use the grō soil tabs in combination with CO2 injection and water column fertilization for best results.
I've used Hydrophyte's GroSoil and GroHumate tabs for two different setups over the past year or so, and I've gotten some pretty remarkable changes in my tanks. The growth and health of all my plants really perked up, even though I was dosing EI, using pressurized CO2, had superior lighting, and a "plant" substrate. The colors, especially for my red plants and cryptocornes really started popping too. I swear by them! I add more about every six months, and it really has paid off for me.
As Barbgirl mentioned, there is a LITTLE dust that comes up if you yank out rooted plants, but it isn't much more than what you would expect by simply removing rooted plants from a substrate without the Gro Tabs. From my experience, the "dust" is quick to settle or is simply filtered out. I've never found it problematic by any means. Certainly, the benefits by far outweigh any sort of very temporary "cloud" that may arise.
One of the best products for planted tanks out there, in my opinion.
