Just Opened My Pool
by: Scott

Just opened my pool and the filter seems to be clogging easily. I backwash, twice a day and that helps. I was told, it would help, if I put chemicals directly into filter. I have not a clue how to do it! Help!

Thanks for the question Scott

First we need to determine why the filter is clogging. This can normally be seen with a working PSI gauge. What's the "just backwashed reading" and how long does it take to get 10 PSI over that reading?

For time sake I've already answered why you may have a loss of pressure or high PSI. You can find the answers in these links:

Clogging would indicate lots of algae and/or debris in the pool. This is just a matter of filtering and backwashing. High PSI a few hours after backwashing and a clear pool with no algae or debris indicates something else and the above links will help. Do you have a sand or DE filter. If DE you may be putting too much DE in the skimmer.

You can put chemicals straight into the skimmer but only if the multi-port valve (MPV) is on RECIRCULATE. The setting bypasses the filter and simply puts the chemicals right back into the pool. You also have much more flow because the filter has been bypassed. it's normally 1 pound of DE for every 10-12 square feet of filter space but check with your filter specs.

If you feel your situation is more complex than this, I do phone consultations for a donation of your choice. It makes things go much faster and many people have found it extremely beneficial, saving them time and money in the long run. All your questions will be answered. I have nothing to sell you so you know I'm not bias.

Pool Consultation

Hope this helps and have a great Summer.
