High Ph and Low Ta

by jj in Dallas » Tue 20 Sep, 2011 19:23

First post

It doesn't make sense to me, but my ph is between 7.6 - 7.8 and my TA is 40 ppm.
Total hardness is 240
What do I do to get my TA up without...

Last post

If the pH tends to rise, then just lower the pH with some acid and leave the TA where it is unless it's very low such as 50 ppm or lower. If it's...

Last post

You can expect to find your TA higher. If other parameters such as pH and CH are also high, then you might see some scaling (lowering the pH should...

Should I have to keep adding sodium bicarb?

It's not so much of an upper limit as a slowing down of outgassing as the TA level gets lower or the pH gets higher. This is shown in this chart . If...

Last post

Test strips are close to useless. It is impossible for your water to have 0 TA and a pH of 8.0. A true TA of 0 would have a pH of 4.5 or below. You...
