Yellow sediment from Seachem products in RO water?
Long time lurker just joined up!
I've decided to start using RO water for a few of my planted tanks as our town water is on well water and KH and GH are pretty high. I buy the RO water from a place nearby (drought here is too bad to get my own filter. Too much waste water). Decided to try the Seachem route of adding Equilibrium, Alkalinity and Acid Buffer to get the GH, KH, and pH where I wanted them. It was a lot of math but I figured it out (so many conversions to perform) and was pretty proud of myself. By the time I was done mixing it up GH, KH, and pH were all pretty much where I wanted them to be.
I had mixed them all up in a 32g Brute trash bin and heated and aerated the water over night so I could do a water change with this batch today. Only when I took the lid off the bin there was a sort of yellowish brown sediment at the bottom of the (white) bin. I mixed it up and from above the water looks kind of tinted though when I scooped out some in a measuring cup it looks clear.
Did a quick test strip test and everything looks OK. Will do a more detailed test shortly. But before I put this in my tank just wondering if this is normal and the sediment is harmless or if it is something to be concerned about.
