I started following the guide "Turning Your Green Swamp Back into a Sparkling Oasis" on Saturday morning. My pH was 7.0 and CYA 30, so I had a target FC of 13. After a few hours, the FC started to hold, so I switched to checking twice a day. I lose a few PPM of FC between checks, and the CC is almost always 1.5. Visually, it looks like nothing is happening. The water is still almost the same shade of green as when I started, if not darker, and I'm not seeing the change to gray/white. I'm cleaning the filter once a day even though the filter pressure does not change (roughly 8PSI), and there is definitely green algae coming out of there. Any ideas on what's going on? There are two problems with my pump/filter system. There's a large amount of air getting into the system. The pump never loses prime, but you can see a lot of large bubbles coming out of the return valves. I just can't seem to fix it. Also, the pressure needle never stays still; it always bounces between 7 and 8PSI. I don't know if those are problems, but figured that I would mention it.
