Should I get a Sand Filter for a 10,000 gallon above ground pool?

Postby c627627 » Fri 22 May, 2020 21:14

Someone recommended a Sand Filter to me for my 10,000 gallon above ground pool and said that this would be a quick & easy way to keep the pool water blue.
I have another 10,000 gallon pool that I may install next to it, so in my case [two 10K gallon pools], can you tell me why I should/shouldn't do this and what my options are as far as models go if you think I should consider this?

My biggest worry is that it appears that a sand filter can only filter debris 20 - 40 microns. Meaning for a green pool problem, it may take weeks to filter the cloudy water? When I heard about this disadvantage, it made me not get the sand filter last year because pretty much the *entire reason* for me considering a sand filter solution is to *not* have to worry about the water turning green...
Thank you for your advice.

Any filter will not stop your pool turning green only proper chlorination will
I have a sand filter and so do millions of others. They are easy to clean/backwash whereas Cartridge and DE are more involved and will clog up easily
You can also add a cup of DE to a sand filter if you have persistant cloudiness
You need to match your filter to your pool and pump so that you are not pumping to fast through the filter (slower is better) Also go for a larger filter

So whats the best approach for my case, all things being equal? Is perhaps the salt water solution "better than" a sand filter solution if the goal is to spend as least time as possible trying to turn green water into blue?

Even if you go for a SWCG you still need a filter. A SWCG only puts chlorine into the pool. Get one that is double the specified output as they are rated 24/7 at 100%

So is your recommendation to not consider the sand filter for the situation in post#1, and instead consider a salt water solution to keep maintenance to a minimum.
What equipment offers the best price to performance ratio?

You still need a filter regardless of how you chlorinate (SWCG, Liquid Chlorine, Trichlor, Dichlor or Cal Hypo)
A SWCG does minimise maintenance if sized and dialled in correctly
I can't advise on what equipment
