If I recall, you said you didn't think you had algae correct? However a CC level of 1 is slightly elevated letting us know something excessive is being processed in the water. Remember, it's important to ensure the water has no algae before finalizing anything for iron. If you have any doubt about algae, even if you can't actually see it at this stage, you can do an
Overnight Chlorine Loss Test test.
Either way, the things I would focus on at the moment are FC and pH. Make sure the pH remains fairly low in the 7.2-7.4 range which will help with the iron. If you have to do a
SLAM Process for algae, you want the pH low anyways. Keep the FC balanced to your "current" CYA as noted on the
FC/CYA Levels. On the non-SWG chart, find your CYA and then the matching FC level. If you have any problems, let us know.
