Here's my test I want to drop the alkalinity down ???

[rolo918]

Fc - 10.5
TC- .5
Ph - 7.5
aly- 120
cya-80

The water is clear and nice should I drop my alkalinity or not
And if so should I use acid

If the pH is stable at 7.5 or so, I would not screw with the TA at all. If pH raises above 7.8 then I'd use acid to lower both pH and TA and then aerate to bring the pH back up.

That's what I was thinking but I want to second opinion.

Thank u
