Re: Black Algae in saltwater pool
Re: the extreme addition of salt.
I see three possibilities since he didn't report any obvious errors on the swcg control panel.
1. If the pool has a major leak and he's replacing a large quantity of water every month he may also need to add a lot of salt.
2. When a salt cell gets old and needs replacing it can progressively read less salt than what is in the pool. Get a Taylor K-1766 or at least some aquacheck strips to confirm salt levels.
3. If the salt cell gets a buildup on the sells. This happens if you don't ride herd on your pH levels. At 7.3 it's not likely the problem. That is, unless it was formerly out of control and above 8 or the cell was never cleaned. Get a Taylor K-1766 or at least some aquacheck strips to confirm salt levels.
In conclusion:Get a Taylor K-1766 or at least some aquacheck strips to confirm salt levels. Also, follow the manufacturers procedures to acid wash the salt cell. This will remove any buildup if that is the cause.
Any one of these would result in the SWCG not producing chlorine properly.
3 Gallons of muriatic in that pool is going to take it down to pH 6.6. Yikes.
