This is fairly easily achieved change over. All you have to do is change piping coming from the pump and to the pool to fit into the new filtration system.
This is a bad idea. Diatomaceous earth (de) will go right through a sand filter. It will end up back in the pool and then it is almost impossible to get out. Sand goes in sand filters, de goes in de filters.
You should not use Aqua Perl (Which is a Expanded Perlite Filter Media), or DE filter media in a sand filter. Here are a few reasons: 1. The Aqua Perl will come out every time you backwash your filter (it is much lighter and has a certain percentage of "floaters" (material that floats on top of water). 2. There are very small particles in both Aqua Perl and DE that may get into your swimming pool causing a "cloudy" effect. 3. Sand is much more permeable than Aqua Perl, and you will get a lower flow rate than with sand. The pressure will be higher as well. 4. A sand type filter is not designed for either Aqua Perl or DE. To use this type of filter media you need a DE type filter. Using a DE type filter will give much better results than with sand.
I am no expert, but I started with a used above ground pool and a DE filter. The DE filter caused me nothing but grief, poor circulation, way too much bumping and replacing the DE powder. I now have a sand filter and it is a breeze. My pool is under a tree, so there is plenty of debris, but that's what the skimmer is for. You need to keep that cleaned out no matter what kind of filter you have.Yes and No- the answer is personal and dependent on weather you prefer cheaper esaiser ownership, or cleaner water with more cost and maintenance.De is a better filter medium, but at the expense of consuming and replacing the filter media each backflush. A sand filter will go down to 10 microns. DE filters down to 2 microns, but the flush process removes your DE from the filter grids and you need to replace it per flush. This process is messy and a bit more time consuming and as a result most De filter go longer between backflushes than their sand counterparts.Backflushing a sand filter more often to keep pressure low is easier in that the process does not remove the sand filter media like DE.
Backwashing is done to clean the filter media in sand and DE systems. Cartridge filter systems don't have a "backwash" provision. You just remove the cartridges and wash off the dirt and debris with a hose.
Sounds like your filter needs to be cleaned: DE < BUY THE FITER CLEANER> SAND: GET NEW SAND CARTRIDGE: BUY THE FILTER CLEANER
Go to the site link bellow for a guide to converting from baquacil to chlorine. Keep in mind that if you have a sand filter you will have to also change the sand in it as it will harbor traces of baquacil.
When you say sand, I take it you mean in the sand filter. Yes, normally change the sand or clean the DE filter when we change the liner since it most likely has been some time since it was changed..
how do you clean jacuzzi sand filter, and replace sand
distinguish between slow and rapid sand filter
Nothing if its a sand filter However if sand is coming into the pool from the filter then you may have to replace one ore more laterals in the sand filter as they have worn and are letting sand through to the pool,
Do you mean how do you install a sand filter?.
If you have a sand or DE filter the setting is filter in the case of cartridge filters it is filter as always unless there are other settings for your particular setup.
