Hi,
I'm pondering in getting an R/O system, in spite of the financial
barriers. Is Seachem's Discus Buffer a workable to lower the GH of my
water? Right now it's at 10 degrees. Would this product lower it to 4
or so? And do so without adding other things that bother discus?
(i.e. sodium?). Thanks for any info. My tank is a 55 gallon planted
tank. My ph is between 6.5 and 7.
