Read the manufacturer's manual on the filter. They give specific amounts of sand for each size of their sand filter configurations. I am not aware of any set formula in general. k My Ranger manual states 18" requires 200 lbs of media.
200 pounds
The best thing to do is to locate the manufacturer on the filter. Sometimes the amount of sand is listed right on the filter next to this name. If it is not, you need to contact the manufacturer as all filters are somewhat different. An average would be 200-250 pounds.
Follow the manufacturer's manual. Use #20 silica sand only. Could be 100 or 200#'s ??? k
You have two options when vacuuming a pool. If it a normal weekly vacuume you will set your filter valve to the filter position. This will send the water through the filter and back to the pool. Once your done vacuuming, you then backwash and rinse the filter. A good ratio is 3 min to back wash and 30 seconds to rinse. If your pool is extremely dirty like at the begining of the year, You can sometimes set the filter to the waste position. This will bypass the filter and send the water down the backwash line. This lowers the water in the pool. If your pool is extremely dirty and you try to vacuum with it set to filter, the filter will not catch all the dirt and some will end up back in the pool in the form of dirty or cloudy water. As a pool profesional I always strived for clear water first. You can't clean what you can't see.
well 1st how big is the filter?...if it's a hayward around 200 lbs...jacuzzi...250lbs...for the norm. inground pool witha one horse pump...no more the 250lbs...good luckanswerCheck the label on the side of the filter for filter specifications.
We did just that. I bought a small above ground pool for the kids last summer (15' diameter) and our yard wasn't level. Digging in the red clay proved impossible so we decided that instead of trying to lower the high end we'd raise the low end with sand. We bought mortar sand, not play sand, and spread it in the area that needed to be raised. Once you add water to the sand it stays in place very well. So well, in fact, that even after the pool was taken down the sand still stayed in place for months. The pool held up the entire summer but the cost of the sand was about as much as I spent on the pool (about $200).
Approximately 200 lbs.
turn you multi port valve to back wash before starting filtration. If your pump is throwing sand back into the pool from the filter, you more than likely have a cracked or broken lateral (finger). To check, remove all sand from you filter and pull the center pipe and laterals out of the tank and check all pieces to make sure there are no cracks. If a crack is found, replacements can be purchased from you local pool store. Or: You did not cover the stand pipe at the top of the filter. Try backwashing a few times and monitor the amount of sand returning to the pool. If there is less coming back you may not have to do much more. If it continues but only slightly diminished then you may have to remove the sand, remove the stand pipe, check the laterals for broken parts, replace if needed, clean the area at the base of the laterals where the stand pipe threads in, install the stand pipe, cover the top opening of the stand pipe with tape or a plug, add water to the tank - to about half full, then add the #20 silica sand - no other grade sand will work. The rest -- you already know how to do. k
that depends on the size and quality of the pool.
I just installed a 15x30 pool. To get the required 2" of sand plus the cove around the edges took 4.5 tons. Here in Baltimore that ran me about $200 delivered from a garden center type place. You may need more if you have really uneven ground or need to do additional leveling. Hope this helps.
The Cm-200 Has no oil filter.
