The inertia of the pen tends to hold it in place when the paper moves.
Chalk (Calcium carbonate) is insoluble. Copper sulphate is soluble. To separate, first place the mixture in wter. The copper sulphate will dissolve, the chalk will not dissolve. When the copper sulphate is fully dissolved, filter the solution. The copper sulphate component will pass through the filter paper, but the chalk will remain in the filter paper. Dry the filter paper to obtain the dry chalk. Evaporate the solution to dryness, to obtain the blue dry copper sulphate crystals.

If you mix a dye with a colourless solvent (e.g. alcohol) and place a drip of it in the centre of a round piece of filter paper, the different dyes will "run" at different speeds and for different distances. You will be left with a series of concentric circles which are of different colours.
it means that your sucking air from the bubble stone or curtain or what ever bubbling airation you might have if it is a bubble curtain that spans the entire tank buy a shorter one and place it down from the filter if it is a stone relocate it to the other corner or away from the filter
