Changing substrates
I was planning on changing out the 2-3 inches of bare gravel for something like flourite and then putting another thin layer on top of the flourite. whats the best way to go about doing this? put the fish and plants into a bucket, remove all the water, do the change, fill up partially, plant, fill all the way, add fish? how can I minimize stress for the fish? is there anything else i should know before i start?
