Hello - I have a stenner 170DM5 pump. If I understand it, i could put a #1 hose in it and tuen it on L (5%) on time and get about 0.5 gal per day. I would like to use it for acid addtion to the pool. I could put it on a timer to limits it time. I have added 168 oz of muriatic acid over the last 14 days. This is 11 oz or so per day. That would say i need almost 6 hours to put in tat amount of acid. If i plum this in after my filter and before my swg, would i hurt anything? should I water down my acid and run it longer? Also, how do the stenner pumps work, when set at 5%, do they run 5% of on hour all in the 1st part of an hour of more uniformialy distributed across the hour.
