After 2 days of SLAM and lots of brushing and changing skimmer socks, the pool is looking a lot better and passed the OCLT last night (evening FC 11.0, morning FC 10.5, no CCs) pre-SLAM #'s are pH 7.9 (added 8 oz acid), TA 95, CYA 45, CH 250. Water looks mostly clear but when I brush the...

Recently noticed a hairline crack on the edge of one of our (plaster in ground) pool steps. Are there reasonable DIY ways to repair something like this? Thanks

Thanks! Will stop at the pool store this weekend. Does Cal-Hypo raise CYA much or is that the dichlor shock that does that?

today's numbers, 17,000 gal rectangular plaster pool. Our municipal water is fairly soft. FC4.5 pH 7.6 CYA 40 TA 100 CH 200 - I see the recommended range is 250-350 in Pool School. How important is it to keep the CH at the lower end of the range (i.e. do I need to head out to the pool store...

yesterday after the kids had a bunch of friends in the pool, I went to sweep and brush and chlorinate, checked pump after its afternoon run and discovered it had lost prime, also discovered a crack in the vacuum hose in the pool so I suspect the pump ingested air for an unknown amount of time...

Ah, got it - thanks for the explanation!:lovetfp:

Was psyched to get the fresh refills for my K2006 from TFTestkits and broke them open this weekend (my pH and FAS-DPD and CYA test reagents have been replaced regularly but I think the TA reagents might have been the ones that came with the kit originally:oops:. I was a little weirded out when...

ours was done by Adams Pool Solutions in 2011 - we had a leak around the skimmer area and they replaced our (probably original) skimmer and voided our main drain as well as replaster. They did a decent job but we had a few logistical snags that I think were at least partly due to our pool being...

might also want to check for local stores that carry Hasa 12.5% liquid chlorine - I like that I can buy them as a case of four 1-gallon bottles that the company reuses, so you pay deposit on the case/bottles with your first purchase and afterwards you return the empty case and bottles when you...

our pool has just a single return and single skimmer and the return is probably original 1960's-era plumbing that doesn't have an eyeball - would this be compatible with the PoolSkim? Moved by Divin Dave

…you roll back your cover and find that another species has decided to make themselves at home in your pool :eek: (yes, I've been a lapsed TFPer during the off-season, FC was down to 1 and there's hecka lots of yellow pollen on the water surface and precipitated out on the bottom. The...

this afternoon we noticed that the concrete around our sand filter was wet and it looks like the leak originates at one of the connections to the pump: Any tips on further DIY diagnosis? Is it feasible to attempt a DIY fix when, as hubby says, "I don't have a wrench nearly the right size"...

Thanks!

Anyone use something like this http://www.poolsupplies.com/product/sku/388149

all right, I knew keeping my test kit in the shed during the winter wasn't a good idea, but I did, and somehow my container of DPD powder got enough moisture in it (lid was open for an unknown amount of time) and now it's just a solid chunk instead of powder:oops:. Is it still usable and if so...

ah yes, acid washing lab ware, how could I forget (well it's been about two decades since I last used a UV/Vis spectrophotometer and had to clean the cuvettes...) Thanks!

FC was 11.5 at 11 pm last night and still 11.5 at 7 am this morning FC at 2:30 pm was 8ppm - is that within a "normal" range of FC loss for CYA50? Water looks bluer than yesterday, slightly opaque after brushing

OK bringing FC up - at 15ppm now. So do I try to hold it at around 20 ppm until sundown? Almost seems like overkill when the water *looks* mostly blue and clear but after a few weeks of maybe-it's-gone-maybe-it's-not I'm wanting to get these buggers chlorinated out for sure. Have done a...

Just did the CC test and no CC detected (my R-003 reagent is a bit old though so could that be a false negative?) Water is clear although there's a slight haze of dust where I brush.

anyone? I'm assuming that a 6ppm drop in FC over a 27-hour period is more than can be attributed to a sunny day's worth of UV's? (BTW what is a "normal" amount of sunny-day UV-related chlorine loss?)

My comparator has accumulated a bit of cloudy residue over the years. Do you clean it out with a vinegar solution or something else? Thanks!

I think I know the answer to this but before I drop another chlorine bomb, I wanted a second opinion Had a mild dose of algae on the side of the pool on Wednesday. Brought FC upwards of 14 (it was 14 at 11 p.m. on 6/12), brushed often, left pump running overnight. 7 a.m. on 6/13 my FC was 13 so...

http://www.troublefreepool.com/pool-school/chlorine_cya_chart_shock for CYA level of 70, chart recommends minimum FC of 5 so it sounds like your chlorine is low for the amount of CYA you have

latest photos with sun on the water: deep end: shallow end: area around skimmer - this is where the yellowish-green stuff was stuck to the wall yesterday. close up of area around skimmer

yesterday noticed some yellowish-green residue on the wall of the skimmer side of the pool (rest of water looked pretty blue and clear) so we gave the pool a thorough brushing and I added more chlorine at around 10 p.m. At 11 p.m. last night my FC was 6.0 and at 8 am this morning it was still...

Bought a 12 mil clear bubble cover from Solarcovers.com in August 2011 (thx to recs from folks on this forum) and it worked great but it started getting brittle and cracking in a couple areas towards the end of 2012 and now we have one zone at the reeling end that is sort of disintegrating. We...

our current pump/filter setup is a Hayward S244S Sand Filter with Franklin Electric 0.75 HP motor and WhisperFlo WFE-3 pump (this was already here when we bought the house in 2006) and we're contemplating replacing the pump with a more energy-efficient one (we're in CA and during the summer time...

This is my family's 5th year of being owned by a pool and 3rd year with TFP. Haven't posted much this season because (drum roll please...) this has been by far my most "Trouble-Free" year of pool care ever :party: . NO algal insurrections, no leaks, and no feeling of anxious apprehension every...
