Hey TFP, looking to soon replace 300lbs of sand in pool filter. Called around and prices are $12 per 50# bags. That seems a lot to me, since you can buy play sand from Lowes for $3. Which leads to this question, Could I use this type of sand. Also I see where some add pea gravel first, what is that about?
Lastly, what should I check and lookout for when replacing the sand. It is a Hayward side mounted multiport.
Thanks a lot,
