Side Effects / Unveiling the Dark Side of Sand Filter

7.How Poolking control the products quality, how many testing before packing?

---Poolking has a professional Quality Control team to guarantee each product is 100% inspected before packing. For example when the filter inner tank comes out, they will make a first water testing before bobbin wounding. After installation all the connections or manhole & sightglass, they will make the second water testing. During the packing procedure, QC team will inspect all the details like wounding, neck, internal resin and so on to make sure no leaking and without flaw.

5.Does a sand filter can use both silica sand and activated carbon together?

----Yes, they can. Silica sand is mainly used for filtration, while activated carbon is mainly used for adsorption. Silica sand is effective for higher water quality requirements. When use them together, silica sand should be placed on the bottom layer, and then activated carbon should be filled on the sand, but the cost of using two media is much higher.

2. How choose a right pump ?

Bigger is not always better when it comes to pool pumps. A pool pump that is too large can hinder filtration and can even damage a pool’s filter and/or heater. It is therefore very important to know the size of a pool before purchasing a pool pump. If there is additional equipment (such as water features) installed into the pool, it will have to be taken it into account when deciding what size pump is going to be purchased. The more equipment is installed into a pool, the more powerful the pump needs to be.
It is important to consult with a pool equipment expert, such as Poolking's Pumps, before buying a pool pump. The team at Poolking will be able to give our customers professional advice regarding the size of the pump they will need to purchase.

9. What is the frequency to replace the silica sand of a sand filter?

----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
