Tackling High-Turbidity Water in Aquariums: High-Efficiency Sand Filter Purification Case Studies and Detailed Parameter Settings

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.

1 .Why no water comes out when the pump is working ?

a. Power failure or motor protection tripped
b. Pump doesn't vent
c. Pump doesn't fill the water
d. Suction line/hose leaking
e. Transparent cover not properly installed - check filter basket - even bolts
f . Inlet suction process is too large g.) Total resistance loss exceeds the allowable range of the pump - recalculate the required pressure
h. Mechanical shaft seal leakage
