Ricordea question
 

my powerhead fell because of the overused suction cup so it fell right beside my ric and couple of them got detached from the rock, no what should I do? I dont know who to attach it back, please help

just place is back on the rock or another rock where there is lower flow in the tank. They will reattach on their own.

Wrap a new rock with them on it in bridal veil to keep them in one spot and they'll reattach on their own. You should probably get another ric where they tore off as a bonus.

I used fishing line to wrap around the ric to rock. Wait like 4 weeks so it securly re attaches and then you can cut the line away. If you use line dont wrap it too tightly or else it will frag the ric into 2 pieces.
