Hey guys, Seven months have gone by and ,"boy let me tell you", MA was the best idea you guys could have came up with. I started buying MA (30%) to fill the bottle of 25L and it took me 2 months at first to use 80% of it. Very, very good improvement against what I was experiencing on my first...

Quick update: I added 1.4L of MA directly into the pool and the pH dropped from 7.9 to 7.2/7.3 right away (within 5 mins). Now the math (from PoolMath) is indeed correct. But I believe as pointed out that the TA might be higher that what is shown by the test strips since it should have taken a...

Dang, it was a complete shot away from the target, perhaps its happening the same here. Yesterday I've bought 25L of MA and I'll start to use them in the pool, when needed (around 0.5/1L to set the pH from 7.8 to 7.3/7.4/7.5 and then use the rest with the acid pump, when it becomes higher than...

You're right, I see it (TA) using test strips from AquaChek https://www.leroymerlin.pt/Produtos/Jardim/Piscinas/Tratamento-de-piscina/WPR_REF_14189273 It gives me a green tone, that is exactly the one from 80 ppm range (I refilled the pool last Friday, so I guess it went up a little bit since...

Thanks for your explanation, I won't have any doubts next time around.

I just diluted because every video I saw on YouTube advised me to. But sure, since I'm already dropping the acid over pool water, diluting is of no much use. I left my pool pump running, but in circulation instead of filtering. I didn't know if it could damage the sand of my sand-filter, so I...

Hi once again, Just a quick update: Yesterday I went to my local bricolage shop and bought just 1L of Muriatic Acid (30% Hydrochloric acid). Unfortunately they ran out for now of those 5L bottles. I checked the PoolMath app and it said I would require 1.3L to drop from 8.0 to 7.0, with TA of...

Awesome. Firstly, I'll try to change from the CTX-15 (14.5% SA) to a proper Muriatic Acid (hopefully at the 31.5% range or even higher if exists). Let's see if the cheaper option brings any obvious conclusions (I'd like to be a brand's fault, but this is the second brand I use and the problem...

Once again, I can't really thank you enough for your time and knowledge. My TA is now around 70 ppm. It has become stable since a month ago (when I decided to be a proper pool owner and set every thing I could to its optimal level), but even with a low value (from 240 to 70 using those 75...

Around 1-2 days when done manually and using the 38.5% SA solution. Doing it using the acid pump took around 4-5 days. The problem is that aeration, imo, should be neglected. The return jets don't create bubbles, just a small turbulence and are significantly below the water line. If that...

Hi guys, thank you in advance for any help you can provide me. Despite other issues I addressed in a previous post, I'm more concerned right now to understand one in particular. To lower my pool's pH (around 8.4/8.5 pH with a TA of 240+), it took me 3 entire bottles of pH Minus (CTX-15) that...

No, no...I really mean 75 L (3 bottles of 25 kgs / 55.12 lbs). Ok, since acid is more dense than water (1kg = 1L) it won't be precisely 75 L, but almost it. It took me 3 full bottles to get it back to 7.0/7.2. If 3 liters took everything back to normal than I wouldn't be wasting so many bootles...

Thanks again for you reply. Very useful and detailed info. I have an acid pump, I was not thinking in using it manually all over the pool. Just thinking in let the bottle right next the water pump and let the acid pump do its work. Just a small hole on the cap so the plastic tub can be dig in...

Thanks for your reply. Just wondering...can you explain me what is the "low fume" around Muriatic Acid? Is it preferable than the 31.5% if there are any differences? And why? Just to know what to buy within the MA range of products. Thanks in advance

Thank you for your input, it surely helps me. I'll try to find a good Muriatic Acid in my local bricolage store, I think I've seen one a few days ago while passing by. And I'll be aware from now on of that side-effect of sulphuric acid that I didn't know about. I'll lower the pool's TA until 50...
