What's the pH of each? One may contain pH buffers and one may not.
The problem with the sea klear is you have to adjust your alk and ph every time you shock. It brings the ph way down. It's a real pain.
Anyway after useing the spa solutions for 90 days it really didnt seem to do the job.Today i switched to sea klear and noticed a huge differance in water quality.It looks much more crystal clear and no foam whatsoever.Yea it sent the ph way up so next time ill reduce the dosage and hopefully that'll help.
