Okay so i got a hold of some hydro designed pH down, this morning i used 25 drops of sulfuric acid just to drop the pH from 9.7 to 6.6 range, results were similar between filtered and non. Today when i got home with my GH pH down i put 10 ml of pH down into each gallon jug, the filtered dropped from 6.6 to 4.7, and the filtered dropped from 6.5 to 3.8, so yeah based on this information the GH pH down is quite effective at dropping pH, will have to be careful as i didn't get any pH up encase i overdo it.
