I did a quick search and I couldn't find the answer...
We have a solar blanket that we used last summer. We had algae issues last summer and thought that our blanket was contributing. Now that I've found this forum, I realize that we also had other chemical imbalance issues!
Now that fall is approaching again, we are getting quite cool nights here in Canada (approx 59 degrees F). We have taken the cover out to help retain the heat and put the blanket on last night -- bubble side down. It is light blue in colour, I don't know the weight / thickness of the blanket. We are going away this weekend. Are we asking for trouble if we leave the cover on for 3 days and nights in a row? We will lose a lot of heat if we keep the blanket off.
Here's our current levels:
FC = 4
ph = 7.5
TA = 110
CH = 310
CYA = 40 (with more currently in a sock in the skimmer!!)
Pool water looks GREAT and I don't want to mess anything up!! Thanks so much everyone!
