bog

I keep Least Killifish and Guppies. I thought I would show them off. The little tank is storage until I build a second colony.

Just wanted to show off my bog filter. The tree looking plants are red mangroves. I also have dumbcane, Pothos, Chinese evergreen, and peace lilies.

Is my bog wood rotting its like dust on the top of it I have 2 peices of bog wood and one has it considerably more but could be due to its closer to the surface. And if it is rotting is it harmful and what should I do? I have 5 zebra danios in which are there temporally as try where there to...

Will bog wood drop my ph I have just got 2 peices of it as I am getting electric blue rams and want my ph in the low 6's. my ph was 7.6 before I put them in when should I check if it has dropped or will it drop at all?
