What am I doing wrong, everything just tries to float to the top? Nothing will stay fixed. Is it best to take the plants out of the containers or keep them in? By the time I had finished yesterday, the fish must have thought a Tsunami was coming! I tried digging holes in the gravel or firmly twisting the pots into the gravel to no avail. Is there an obvious method that people use. Also, I bought an air pump system which came with an air 'stone'. I wrongly assumed this would be heavy as in ' a stone', but this also keeps floating off the bottom.
