Ok here's today's dilemma. Currently we have no sand filter - it apparently wasn't winterized correctly and we've had to order a new one. In the mean time, we've rerouted the plumbing lines so that we could at least still run the pump and circulate the water so it wouldn't become stagnant.
Here are my current readings...
TC - 0
FC - O
pH - 7.5
Alk - 160
CYA - 0
The FC was fine yesterday about dusk and it is 0 zero... it is falling way too fast and I need to shock it. And I also need to get the CYA up, correct? Some sites say it's not that important but 30-50 is recommended. How does the CYA effect FC? And is it pointless right now to continue to put chemicals in it until the sand filter comes in?
