Iron in water source

[stcohen]

AM:
Have backed off to 1 tab per skimmer per day. Will vacuum to filter this morning and see if it will catch and hold the sediment. I really do appreciate your help

PM:
pH 8.0, Vacuumed to filter. Basically captured nothing, returns basically putting what I vacuumed back into pool. No change in pressure and returns remain strong. Getting pretty frustrated.
