I don't see a problem with planting HC in an established tank.
The pics I posted the above, the HC was planted after the tank has been running for around 2 months (I set up the tank but didnt' have time to plant the HC for 2 months..)
It turned out great. The 3rd pic was <40 days after planting the HC.
I am definitely not a fan of emerged growth.
I have tried growing HC 2x submerged & 1x emerged.
On both submerged occasion, the HC turned out great. I got a thick and bushy carpet.
on the emerged occasion, I barely had any growth, the leafs & stem looked small and weak. When I fill up the tank 1.5 months later, more than half of the HC was gone within a week. That's just my experience
LOL - your water was so clear I thought that was emerged growth....
Good info, thanks, Choco. It occurs to me that I wanted to add an additional member to the tank, an albino bristlenose. Does it make sense to hold off on adding that bristlenose until the HC has established its root system, or is the fish gentle enough over the bottom that it wouldn't likely uproot the new plantings?
Also, another noob question - I have used my hands for all of my plantings - and far too often, uprooted existing plants just to get a hole for my new plant. So I end up either moving, like a bulldozer, a lot of substrate around, or dumping additional substrate to anchor plants - and I'm about out of all the height I want to add in the bottom.
People mention tweezers all the time - sorry for the question - how does one actually use the tweezers? Do you dig a hole with your hand, grasp the plant with tweezers and hold the plant while you place it and overlay with substrate, or are tweezers used to gently push a plant down through the substrate (or would that kill fragile root systems)?
I'm sure it's a naive question, but I'm considering getting a pair of long tweezers and scissors, just want to know how I'm supposed to used them (the tweezers - I get the scissors, LOL).
