OK so we just got this summer cabin that was my husband grandfathers. It has a 18' diameter pool they said they normally kept it at 4-5 foot deep. It has not been used in multiple years. We went up to check it out last weekend. Pulled off the winter cover to find algae. I took a look at the filter that they had and I am a little stumped. It is a metal container, they said it was a sand filter. But I do not see a lever to switch from filtering to backwashing? It has the name Lomart on it and they said they got it for free from a friend years ago. We are in a colder climate, so pool would only be operating for about 2-3 months Now for my questions.
1. Should we just get a new filter, or if you think we could salvage the old one, where should I look to figure out how to work it??
2. I looked up how to get rid of the algae, but I am not sure which chemical route would be best for us. We are willing to devote the extra time initially to clearing up the algae, but once it is clear we will only be at this summer home once a week, sometimes every 2 weeks. IS there a convenient way to clorinate the pool while we are not around, or should we give up hope of having a pool at the summer home because it would not be feasible to maintain it without being there constantly?
