higher pH

[marinakid]

just bought the crystal pro filter, use that for my salt mix. and i found out that it give a higher pH compare to using tap water.

tank pH is 8.4. using salt mix with DI water is 8.9

can anyone help?

Hi Michael.

Tap water PH can be as high as 9.4.

aerate the salt mix water overnight and it will be ok.

always prepare the water 1 night before performing water change.

this is the reading after overnight. as i know that it is alway recommend to prepare salt mix overnight.

i measure yesterday, and found that it 8.9. so thought today will be lower. just measure. still giving 8.9

did you put in an air stone and aerate it over the or simply just left it there in a pail overnight?

you may want to check your PH meter..

after some time you may need to calibrate it..

just a possibility,

assuming if the fault lies with the PH meter,

no matter what you do you cant get your desired 8.0-8.3

Did you test the PH of the water before and after it passed through the Crystal Pro DI filter?

Anyway, you need to use an airstone to aerate the mixed salt water in order to bring down the PH of the water.

water before DI was 7 after DI become 5. so having a lower pH after mix salt shouldnt it be lower.

i using powerhead to circulate the water. not using airstone to aerate it.

So just to recap. You measured the tap water and you got 7, then after you run the water through the Crystal Pro DI you got 5 and after you mixed the salt, you got 8.9 and your tank PH is measured at 8.4.

What was the PH of the salt mix when u used tap water previously?

i was still trying to recall what pH i got previous using salt mix with tap water. i guess it around 8.4 since i didnt do any adjustment.

i will go do a quick test using tap water with salt to see what i get.

after checking, realise that using tap water i am getting pH of 8.9 also. can it be the batch of salt mix? i am using tropic marine.

realise that this box have alot of sediment in the salt which cannot be dissolved.
