try the following site there is a silica filter there with the number 0-1740-xxx it may be the one you re looking for
Give something more attractive to pay attention to...such as a commercial wasp trap. You can also make your own trap by supending a piece of salmon by a string over a bucket of soapy water. tie the meat about an inch above the water.
To determine how many gallons of water it would hold, you need to first calculate the volume, which requires knowing the height, length, and width. For a circle, the diameter would probably be the 24' value, and the height would probably be the 4' value. Volume can then be calculated by using the following formula:
V= hπ r^2
v = volume
π = pi (~3.14)
r = radius (which is half of the diameter, and in this case it is equal to 12')
h = height = 4'
Now we put in the numbers and calculate:
V = hπ r^2
V = 4 π 12^2
V = 96π = ~301.59 ft^3
To convert cubic feet into gallons, multiply the value by 7.48052, which gives you 2256 gallons
Depending on size of pool -- add at least a gallon of 12% chlorine brush the pool and run the equipment as normal. Check and add or adjust chemicals upon your return. Or use your neighbor and have him add X amount of chlorine or hire a pool tech for that period. Most will have a package price for you.
