Oceanic Sea Salt - Low PH levels

I have switched to Oceanic Sea Salt because i like the fine powder which dissolves easily, I was using IO but seemed like they had some kinda white filler in their salt which would never dissolve.

Anyway I use RO water from the local grocery store and mix it in a 5/gal bucket with a power head and a heater for at least 24 hours usually more.
The ph level of the water tests low 7.6 - 7.8 ish. any ideas? all other tests seem to be fine.

Now i could be my test kit i am using the 5 in one quick dip tests.

Any ideas?

 

I only use IO, and never really had a problem with it. I mix 5g buckets a time, put a powerhead in it and in 10mins or less, its crystal clear.

9 times out of 10, you have to adjust the ph in your salt mix. I have heard that the new red sea pro coral salt has ph buffer already in it, but I have never used it so I have no first hand knowledge of it.

 

yes thats right i use red sea pro i have a good ph reading of 8.3 9 out 10 times but watch calcium levels as it has calcium for 450ppms

 

Ive thought about ordering it for the my next bucket... any bad effects to date?

 

high calcium but recently worked out the use of alk buffer..dont know if it was salts fault though :-/

 

450 isnt high calcium, thats "just right"

 

I keep mine between 430-450

 

i didnt add it sorry ive had 600ppms

 

damn! the 600ppm were as a result of the salt mix?

 

no due to my inexperience and using a dodgy drop style hydrometer
