I had an elephant cover installed at the end of last season but much too late - after most of the leaves from nearby trees already entered. Before opening, the middle of the cover was indented all the way down and I opened to water level that was 25%, and hovering around the middle of the pool light. I found a video online that says it is most likely a crack in the back light casing that can be patched with a product called Groov with the pool filled. I added bleach and filled the pool which is dark green. I ran initial tests and this is what my numbers are (will do a test early morning for overnight results:
PH 8.0 (or higher, was more pink than the highest one)
CYA (Dot didn't disappear even at highest level of 30)
What do you suggest I feed my pool with these numbers?
