why is my pool water brown and green. i used iron chemicals. and shocked still the same.?
my pool water was clear when i filled my swimming pool, then i added chlorine and it turned brown almost instantly. i purchased iron and medal chemical and it helped alot and then i shaocked it about 3-4 hours later and it turned brown again.the bottom of the pool has a lot of resadu on it and when i tuch it it floats away i think its the iron from the water. how do i get that to filter out.what should i do to get crystal clear water. im going crazy. the pool is above ground 14″x3 1/2 deep.. thank you
Cynthia so far is the closest one to solving this, don’t listen to these others
Everybody is a closet pool pro. I once had a customer swear he could check Ph with his finger, but then again he’s the same guy that we had to do a complete filtration and heater swap out because it was eaten by low Ph and TA. It’s hard to diagnose an issue without seeing and a little more info would be helpful, but here’s a few things to do and look for.
I have to assume it’s well water you use for fill. The green is normal, it’s algae. Even city water pools will have a slight green tinge when they are first filled and not yet going. Filtration,correct water balance ( Ph 7.2-7.6 ,Cl 1.5-3.0 and TA 80-120 ) and a shock will keep the green monster at bay. The chlorine reaction you saw, was likely one or both of these: 1/ Reacting with algae (usually a foam or bubble action) or 2/ Reacting with iron bacteria causing brownish lumps to form in the water column.
The brown ,in all likelyhood, is iron. It’s prevalent in well water and most outside taps used to fill pools, don’t run through your house’s water softner. The metals remover you added will cause metals in solution to fall out, dropping to the pool bottom. Normal. Just vac it up with filter set to waste. Make sure the pool is filled all the way to do this, as you will be removing as much water as it takes to clean the bottom. If you did it on “filter”, you’ll plug it up in no time and the amount of backwash water used will be even more, by the time you’re done. Also, before you add any thing else to the water, take a sample, in a clean container that you rinsed in your pool water to your local pool pro. They all have Labs and will anaylize your water for no charge. Take a sample of your fill water as well. If the iron is too high, you may be wise to find an alternate source or change your plumbing slightly, and use the softner.
