Which lighting sticky? I saw one about PAR but I think it was off-site but I couldnt really understand the graph they had.
I can look around for pool sand, Its pretty bright compared to play sand and it'll show off the plants better and the black kuhlis and pepper corys but I cant find any in my town. I can look around though.
The tabs do release the ferts over time, but on another forum I posted almost the same thing and I was suggested to crush one up to give the tank an initial boost for new plants after the travel of a few hours. Big Als is 2 hours away from me so I can only go there when I know I can make the trip worth it
