If you haven't seen it, I have a thread going in the Getting Started forum about opening my pool, Converting swamp to pool. To summarize, I have a ~38,000 gallon pool that has been neglected for 3 years. It has tons of debris, a ~20 year old DE filter, and old vinyl liner. I've gotten some help from that thread on getting the pool cleaned up, but I've run into a problem with my filter so I'd like to get a recommendation from the experts here.
When adding DE into the skimmer today I noticed it shooting back into the pool through one of the jets. I opened up the filter and saw several tears in the fabric of the grids. Guy at the pool store said I would probably have to replace the grids or get a new filter, but he said if I wanted to save money I could try sewing the tears and covering them with super glue. I did that, but the DE is still coming back in the pool.
I have a 2hp pump, 1.5" piping with 2 skimmer intakes and 1 main drain, and a 38 sq ft DE filter. I can either get new grids for the filter for $150, or I can get a new filter. So my question, is the 38 sq ft filter big enough for my set-up? If it is, then I will just get the new filter grid. If not, should I get a 48 sq ft or 60 sq ft filter? I tried reading the sticky but I'm a bit confused. I'm thinking that my piping and filter are undersized for the size of the pump and the pool. Any help is very appreciated.
Here's my setup:
