Can't get down to 6.8 ph
On the advice of my LFS, I'm trying to get my ph down to 6.8.
He insisted I use Seachem Neutral Regulator and Discus Buffer. He also told me that he uses it in all his 150 tanks and all his customers use it without fail. He seems like he really know his stuff.
That said, I started down the road to try to bring done my ph. I've never down this before, so I really have no idea what I'm doing. The owner of the store told me to treat for 5 days with a slow-drip treatment.
After day 5, my ph was still high, maybe 7.4 from around 7.6 or 7.8.
He told me to go 3 or 4 more days. The ph is still around 7.2 or 7.4 (it's hard to tell)
So I was pretty much following him blindly without doing much research, because he has some rare freshwater fish and all the fish in his tanks look really healthy.
But after dosing 9 days for our 5.5 gallon and seeing almost no shift, I'm not sure what to do.
And now after doing some research and finding out that Neutral Regulator and Discus Buffer are phosphate-based and that can lead to all kinds of algae, I'm even more worried.
Did I get some really bad advice? Or have some people had success using phosphate-based buffer?
Our tank is mostly java fern, java moss, a few petite anubias and one normal anubias.
