How about if you use glass media n a sand filter?

Another fellow suggested waiting until the return flow coming out the jets was noticeably reduced. Not based on a PSI reading, nor a time interval. His rationale was that a sand filter works better with some level of dirtiness to it, that it catches smaller particles as it gets dirty. He said that frequent backwashing actually reduced the ability of the sand to catch smaller particles.I wasn't sure what I thought about that. Some of the things he says seem to make sense, others not so much. He strongly discourages using liquid chlorine, I'm a huge proponent of it and use it to excellent effect in my pool. Do you have any thoughts on this? On a related note, Orenda have a procedure for cleaning the sand in a filter and state that sand can be used for MANY years if you clean it thoroughly from time to time. It's a minor PIA to do it but they show evidence of its effectiveness. Do you have any thoughts on that as well? Thanks.

Oh we must need sand changed. (Ten years or more.) Dah!? How? Solar has not been working and some air bubble troubles. Reno time. Give suggestions please. I just subscribed. I'm a dyi guy. Going to replace a valve, motor and chlorinator and add a bypass ozonator, etc. Thanks. Ps, you should just come over since this will be a great example for your tour! Richie The Sailor ⛵️

What does it mean that I have to do it every couple of days or the pressure gets too high we only use it once or twice a week

You should mention the duration of the backwash and also the rinse.

[MtgCoach]

You mentioned that sand more than 5yrs old will be compacted. Not quite sure of your meaning. If I open the filter up & displace the sand by moving it around, will that extend the "life" of the sand? What am I missing here? Thanks

How often do you backwash a DE and how many scoops of DE powder you need for a 10000 pool? Also, how often do you need to clean the filters. Thank you

How many minutes do you backwash your sand filter and how many minutes also rinsing it?

[bsizzlehill]

Wow. Sorry but I think thats way too much. I say backwash every 4 to six months depending on the filter pressure and how much dirt is surrounding the pool. I think its impossible for a sand filter to get plugged up that fast unless its a community pool.
