Well, that absorbent and yellow and porous cartoon character lives there, of course. But, what about in the water at the bottom of your pool?
When my son and his family moved into a “new” rental house a couple of years ago, they invited me over…and told me to bring my bathing suit. I wasn’t too sure why in heaven’s name they would want me to come over to scare my grandchildren like that…they were usually pretty protective of their kids, you know, no scary movies after a certain time of night and so on. But then I figured that if they had turned into mean monsters or something, I should probably oblige them (didn’t want them turning on me). Still, I do love my grandkids so, instead of a bathing suit, I put on a pair of spandex shorts and thought, “That ought to do it”…and headed on over.
I was very happy and relieved to find out that the reason for the clothing request was because their new house had a nice in-ground pool and they wanted to surprise me with a cooling dip! Relieved, I jumped in the deep end, spandex and all!
Turned out the kids were just as scared of a large, shiny, Spandex covered keister carousing in their brand new pool as they would have been of a very large, flabby whale in a turquoise tankini flopping around in the water. Who knew?
Anyway, after a good deal of splashing around, my son took me on a tour of the house and their nice yard. I couldn’t help noticing that their back-door neighbor also had a pool. It would be a nice pool, I told my daughter-in-law, but was it supposed to be that shade of green?
Even for those who use their pool all year ’round, most won’t use it quite as regularly during the off-season, unless it’s an indoor pool. And once pool usage goes down, so too does the close attention it would normally receive.
Mustard Algae, not the same as Green Algae; requires strong chemicals to kill.
The green colour in an unused, unkempt pool is the result of algae. Algae will grow when a pool’s phosphate level rises and kills what chlorine is present to prevent its growth. Of course, during times of most usage, pool owners tend to skim, treat and shock their pools on a regular basis and only notice the algae after it has overwintered.
Off season, leaves and dust can collect on the surface, rain…well…rains down, bringing all the environmental pollution with it and birds drop their…err…droppings and other bodily wastes into the water. Insects (which actually do defecate) leave their…umm…leavings and sometimes just drown. Nitrogen and carbon are now part of the pool’s water system.
Add to that, debris from hurricanes and storms, whether from high winds or flooding, can also contribute to materials deposited into your pool. In short, unless you pay attention to your pool all year ’round, including covering it when it’s not in use, it can become a full dinner plate for algae to feast on, as all of the trash begins to rot and produce phosphate…gourmet algae food.
If it was just the algae, a good shock or 2 might clear it up. But you have to be vigilant; health problems can arise when people tend to think, “Well, we’re not actually swimming in it everyday so I’ll just put off treating the pool for awhile.”
The problem is that if you leave it too long, more than just green algae can start growing in there; black algae which looks much like black mold is growing on the bottom of your pool, mustard algae which is rather difficult to contain because it breaks down easily and resists regular chlorination…even pink slime (yes! that really is its name!) which is not algae, but a type of fungus and which can trigger asthma attacks in susceptible people.
Pink Slime Algae
It’s very much the same as when, at the sea shore during a “Red Tide” algae bloom, the elderly, the very young and anyone with breathing difficulties from any source are cautioned to keep their distance. Also, bacteria of all kinds love to grow in rot and if you have an open cut or sore, you open yourself up to a world of possibilities where your health is concerned.
Can it get worse? You betcha. The last thing you want to think about when you’re swimming is what tiny creatures might be swimming beside you. The fact is that, according to the Centers for Disease Control, any pool can be contaminated with parasites like Cryptosporidium (also chlorine resistant) and bacteria (like E. coli from fecal matter). If you’re not careful, you could find yourself in the emergency room with a really bad upset stomach or a scary-looking rash in places you’d rather not have them.
So, if you’re spending time around a green pool with pink slime around and in it, and your asthma or tummy starts acting up, or you notice a rash travelling up your body or across your face, it would probably be a good idea to call a doctor as soon as you can!
Oh, and if you see something that looks like a pineapple growing under your personal “sea” and if you spy an absorbent and yellow and porous something crawling out from under it, you might want to contact the nearest pool guy you can find in your phone book or online! Better yet, if you’re going to use your pool all year, test it often and keep it clean!
Note: I’d like to thank my son and daughter-in-law (you know which ones you are!) in advance for not holding me liable for the little bit of poetic license I may have taken!
