Problem: I"m new to swimming pool care and have a newly replastered 7k-gallon pool. We began up with muriatic acid around 5 main ago. The pool company told united state not to include any other chemicals till the pH stabilizes. It"s still getting high, so us keep including acid, yet it additionally started to prosper algae, so a pair days earlier I shocked it, and also now desire to include the remainder of the chemistry anyway. Questions concerning how to include chemicals:1) carry out I include the 1" chlorine tablets right into a dry floating dispenser, climate drop the dispenser into the pool, or do I submerge the dispenser an initial and then add the tablets?2) have the right to I include CYA and chlorine at the same time, and if not, which go in first, and how lengthy to wait before adding the other?3) exactly how long come wait after including muriatic acid before including chlorine and/or cya, and also should the floating chlorine dispenser be removed from the pool when adding acid?4) I put in a lb of shock right into the pool 2 days ago, and also now TC and also FC are earlier to zero (but it eliminated the algae and also made the water pretty again). Must I shock again, or just add the common chlorine?5) TA is low right now, have the right to I include baking soda together with the chlorine and/or cya, or execute they essential to be included separately, and also how long to wait in between?6) any other chemical safety worries to be conscious of, as well as the evident (don"t ingest or obtain it in eyes, ns wear gloves and goggles when managing dangerous chemicals)Thanks in advancement to anyone who deserve to help.FC: very lowTC: an extremely lowpH: 6.5 (was 8.0 this morning - included too much muriatic mountain oops)TA: 40CH: 250CYA: 0My pool: 7,000 gallon in floor plaster pool through waterfall spaPool chemicals: only muriatic acid and shock therefore farMy pump & filter: 48sqft hayward DE filterOther info: us live in the desert, it"s hot and also dry and also windy and also dusty - pool gets dirty easily

Ok, I believe the advice you have actually been offered is really wrong. Top top a fresh plastered pool the surface has to cure before the pH will stabilise. The best means to do this is to load up the TA level with many bicarbonate the soda. This creates calcium hydroxide which develops a tough and pH steady surface. Adding acid will simply keep top top softening the plaster surface so it will not cure.By all way add chlorine, ns would use the 3" tabs and the dichlor variation to include the extra CYA friend need. If you have actually CYA in granular type use it but after the bicarb has been included and fully dissolved right into solution which can take several days. Friend will have to waste some of the water as the TA will certainly be high 250-300ppm.For much more expert advice ns suggest getting hold of Kim Skinner the US"s foremost expert on plaster surfaces.

Thank friend for your help. I just included two pounds of salt bicarbonate (it was all that i had), which should raise the TA around 30ppm by my estimate, and I put the 1" chlorine tabs in the dispenser (again, this is what I have for now, and also can"t run out to the store conveniently with tiny kids in ~ home). I have granular CYA, will include that in a couple days. I likewise have a 121oz jug the walmart save brand 6% bleach, might I go ahead and add that later on this afternoon to boost the chlorine levels faster, or will it dissipate too quickly without CYA?

Hi Elle,Yes evaluate you can"t just run come the store, i would add the chlorine after sunlight down, it will last much longer that way. Most pools in full sun the chlorine lasts roughly 2 hrs without CYA.
