How long should you wait after adding the muriatic acid before swimming?

Anyone have any experience with fiber optic lighting. I think I need to replace the bulb, a 150 watt metal halide lamp. Anyone know where to find a replacement bulb and how hard it is to replace?

I replaced the pressure gauge and it is reading 16 which is more like normal. I have shocked the last 2 nights and plan to do an overnight test in the am. Here are my numbers from tonight. FC 15 CC 0 TC 15 pH 7.5 TA 130 CH 280 CYA 40 temp 45 Am I on the right track? If I don"t lose any...

My SWG stopped working last year and I don't think I will replace it right now so the pool is basically the BBB method. Do I still need to lower my pH and TA or should I just go ahead and shock? If I do lower pH, how long should I wait after I add the acid befor adding the bleach?

fc 0 cc 0 tc 0 pH 7.8 t/a 120 ch 250 cya 50

Never even thought to check with pump off. When I tried only went down to 30. Returns all flowing fine. Could 30 actually be my zero point? At 50 if didn't seem to be running hard like I would expect. Should I go ahead and test my water after running for 1 hour and them get chlorine to...

Just opened the pool today. Everything went smooth with the start up. My only issue is the psi on the filter is running at 50. Do I just need to backwash? Last year it mostly ran around 20. I want to get the water circulating so I can test and start adding chlorine. The only thing I tested...

Ok, pool has been shocked. The overnight FC loss test was .5 my test this am fc 9.5 cc .5 tc 10.0 pH 7.5 t/a 120 cya assuming 30 (added 8 lbs stabilizer) I am leaving my swg off until i can clean the cell. Question: At what level is it safe to swim? Just allow some chlorine...

If i shock at night and then FC falls to safe levels by morning, kids can swim during the day?

Would it help to keep the solar blanket on while shocking the pool? Will this reduce the amount of chlorine lost to sunlight?

New test this am fc 0 cc 0 tc 0 pH 7.5 t/a 100 ch 360 cya not tested since just added last night so just keep adding bleach to get my fc levels up? Should I go to shock level now? Did my fc level not go up because of the live organisms in the pool or walmart brand bleach?

I added 2 gallons of bleach to get FC to 3, 120 oz of muriatic acid to get pH to 7.2, and 4 pounds of stabilizer for CYA levels. I need to add another 4 pounds-should I wait until the other is dissolved to add the remaining 4 pounds? How soon should I test? tonight or in the morning? Thanks...

Thanks How long after i add the bleach before safe to swim?

Do they sell stabilizer at walmart? or do I need to go to pool store? I have some muratic acid, so start there right? How long before the kids can swim? My full results this am fc 0 cc 0 tc 0 pH 8.2 T/A 140 CH 420 CYA 0 Thanks again. I feel like such a pool idiot!

My pH looked to be around 8.4 and my TA was 140 my question is should I use Trichlor since it raises FC and adds CYA while lowering pH (according to pool calculator)?

I also tried to test for CYA and not sure I performed correctly. The black dot never disappeared. Was the solution supposed to be clear or colored? We just moved in to the house, the water is clear but looks dirty or algae on bottom of deep end. The only thing I have done so far is added...

Just got my kit and tried to test for chlorine level. I added the r-0870 and nothing happened, no pink just clear. I used the speedstir to mix and still nothing. Tried another scoop and still clear. Any suggestions or is my chlorine level just to low to register?
