Only use manufacturer suggested dry-erase markers on your whiteboards, not permanent markers or pens. Erase board after each day's use, if your board is used daily, the cleaning should be performed at least 2 to 3 times a week. Allow ink to dry, waiting 8-10 seconds before erasing.
1 Installing an aboveground pool can cost $1,500-$5,000; for in-ground estimated costs are $7,000-$16,000 for a vinyl-lined model, $15,000-$25,000 for a fiberglass shell and $17,000-$45,000 for concrete or gunite. 2  However, custom designs can run prices much higher.
A concrete pool will cost you between $35,000 and $100,000 or even more. An average-sized concrete in-ground pool costs about $50,000. It is not just the cost of the pool itself that you have to consider.ool fencing starts at around $100 for a 2.4 metre length of approved fencing and installation will cost you between $50 and $100 per linear metre. Fencing for an above ground pool will probably be on the lower end of the scale.
