Hard rinse to foliage and roots is what I do and, thus far, no problems. Is this an outdoor system?
It is an indoor system.
That's what I had done in the past. I had heard you could put them in your tank after rinsing the roots off and the fish would eat any bugs they found.
I had good luck with the last introduction and hard rinse. I did pick off one nasty critter the same afternoon. Those four are doing well. And that was pre-fish!
I floated the strawberry runners I dug in the tank and planted them. I needed to add plants to bring my nitrates down since I have fish now.
