Logging for logging reasons.
First use of muriatic acid in a water change today. Went with the %20 concentration as opposed to the %38 concentration.
Initial:
25 gallons RO water
ph6.9
tds 15
Added 10ml %20 HCL solution
ph@ 2 mins 3.7
tds 130
I'm expecting the ph to come back up over the course of the day. I'll probably let this mixture circulate for the next 8 hours or so before I decide what to do with it.
Edit: using 700gph pond pump plus large airstone for circulation and aeration.
Second edit: To be clear, I'm doing this in a plastic container with no fish. Also, for anyone who may or may not be reading this now or in the future, muriatic acid is nasty stuff. It will burn holes in your clothes, your floors, and you. I do not condone anyone doing what I am doing now without having the proper safety equipment and knowledge.
