Hey all, so to summarize my issues to date I thought my pressure issue with my pool filter was related to algae previously but it seems that is not the case?
I fought off algae with yalls help (none visible but definitely was losing too much FC) and I SLAM'd for a few days a few weeks back and got my problem fixed. My filter pressures were consistently 9-11~ range for weeks and at the time I was only using two speeds on my VS 3450(max) and 3000(about 85%) 24hours a day.
Pressures on filter were fine for weeks until a few days ago I wanted to tweak the overnight to a lower RPM. I put the speed for overnight to 2200RPM for around 8hours. Now I get an air bubble that forms (Ive read here this is common with VS) but the pressure in the tank jumped up like 4psi (during highest speed cycle) after the first night after the change then after the second night its up another 4psi sitting at clean?? I vented the filter and there was definitely air. To be safe I did an Overnight chlorine loss test twice I lost 0 the first time and .5 the second. I added more liquid chlorine this morning but Im puzzled why my pressure is doing this? any thoughts? All pressure readings I do are when pump is running at my highest RPM).
I still need to tweak my cya higher but I want to figure this issue out before I do anything else. My test results are in my signature. Thanks for any help!
note: I have not backwashed since I took apart my filter for a deep clean about a month ago, I can certainly do that if required but it just seems fishy that when I made this adjustment the filter pressure issue appeared. Prior to adding my VS I only had to backwash once every 2-3months.
