I'm debating about deep cleaning the filter then removing some of the gravel (maybe half) and adding sand on top so it would have two layers of filtering media.

I have gravel in my filter I have seen a few puffs of gravel in the backwash sight glass but that seems to be new this year, I don't remember it doing that last year. and it doesn't do it every backwash. I contacted the filter manufacturer and they can't tell me what height the "sand" is...

the DE article says you may need 1 to 2 cups thats why i've tried 1/4 and 1/3 cup and it doesn't rise a noticeable amount after a few minutes it just plugs up in one day. I don't use DE year round either I am just trying to polish up after my slam. But tonight I came home and pressure was at...

muriatic acid is way cheaper than PH down but for the qty required for a spa it isn't too bad and easy to handle.

TA will adjust as you adjust the PH. mine likes to sit around 40 and the PH ends up high 7's low 8's If I try to force the PH lower the TA gets too low and then the PH gets eratic.

somebody may have peed in it. I don't add more than 100PPm of calcium in my spa but definitely more FC s required, also I find if the air vents are only a little open it can make it seem cloudy but they are just air bubbles.

I seem to have an issue with my filter. Just finishing my slam and my filter seems to plugging up quickly when I add DE to it. I have a feeling this is normal but I would have to backwash daily if I keep adding DE. without DE I can go several days almost a week without backwashing but if I...

I think I will try it. All the pool equipment gets drained (filter) / brought inside (Pump) for the winter due to freezing temps. the water is actually crystal clear when the ice melts but I can see sediment and a light green haze on the bottom. The first time it happened last year I just...

I had two years straight of opening my pool to a green pea soup and was wondering what I"m doing wrong. first year opened to a clear pool and I would say it was the year I was learning so may not have done everything right but I wasn't expecting my second and third years to be green. I...

just let the TA ride. I have the same problem and can't seem to stop having to add MA to my spa but maybe try and target 7.8 instead of 7.4 by the time the PH starts to sort of stabilize it is usually time to dump the water and start again. hopefully someone else will come along with a better...

my son went in before I could test and there was no BR by the time I tested so I added 50ML of LC and got up to 5.5 BR and added another 25ML LC for overnight and will test tonight to see what kind of daily losses I am looking at.

I added about 40 grams. it is 99% from spadepot. I purchased in the US and imported on a road trip. Instructions on bottle said 1/2 TBSP per 100 gallons. I will test tonight and see where I am at with the BR.

So I've gone and done it. added about 1.5 tablespoons of sodium bromide and am trying to adjust the bromine level slowly. I started out with 3.5 FC and then added the sodium bromide. then tested BR and was expecting around 7.5-8 but I got around 2 so I added 20 ml of older( 21 081 date code)...

You americans and your complicated measuring systems. When a US product says to use 1/2 OZ of a granular product is that by weight or volume. How can a useful system have the same units that are two different things. they do say to use 1/2 a level tablespoon too. both of those are per 100...

finally got some sodium bromide and I think I want to try it. I am due for a drain and fill in about a month so if the bromine doesn't work out I can change fairly quickly. I never did end up using the bromine 14.7% stuff I bought. So I have been running my spa on LC for more than a year but...
