I was tempted to answer that with a simple sarcastic “Hire a professional”, but most of my buddies and fam reading this, and other folk, probably have a ‘hands on approach’ to things like I do…so, how do we go from a gross swampy, dirty, unhygienic health risk to a crystal blue refreshing sparkling clean swimming pool?
Answer: Hard work.
First it’s important to test the water, you get the pool algae meter testing kit from any pool store and you just test whatever water/residue is in there for the dangerous fungi/algae, 9.9 times out of 10 it’ll turn out to be fine, but you need to be sure. In the instance it returns + for classA algae etc, contact a professional to come give it a chemical wash. Otherwise follow the seamlessly simple yet tiring steps below:
Hose it down, a few times, and then let the pool’s pump drain as much as possible out, they’ll usually leave 1/4 to a 1/3 of a meter of water as the pressure stops there, that’s fine.
Be sure to remove the deck drains around the pool, you’ll be surprised at how dirty it can be, also be sure to scrub the plastic grills out really well. Over summer/winter, the chlorine and summer temperatures wreck havoc on those grills and leave nasty grainy residue that ends up chipping away and mixing with the excess pool filter, which in turn causes your pool to murk up faster.
Scrub everything from top to bottom with pool disinfectant and your choice of KID FRIENDLY non chemical anti algae/bacterial scrub. Scrub the lights if you have any and test them for exposed panellings, and scrub in between the tiles too, as well as the steps or ladder if you have one. You’ll need to drain the pool a couple times, even if you think it’s sparkly clean, do it over again twice or three times to be 100% sure.
I personally use a small pool pump I got for $90 to finish off the job and pump out the remaining 1/4 – 1/3 meter of ‘eventually’ clean/soapy water. I do this before the first 1/4 fill test. Fill you pool 1/4 of the way then turn on your pools outer pump and drain it, to clean the pumps pipes etc, and once done, fill it up one final time.
That’s pretty much it, if you get loose tiles stick them back into place with tile glue and wait 24hours before filling it up with water, be sure to scrub it clean beforehand.
To maintain the sparkly blue, specially during the hot summer days, use anti-bacterial kid friendly chems daily (make note of the amount to be used based on the size of your pool), add the necessary amount of chlorine, and 3 times a week, add anti-algae powder to the sides of the pool to keep it crystal clear. (usually wait 1-1.5hours before swimming after adding all that stuff).
