When I backwash, I lose some filter media. This year I was going to change it out but after some research it seems that I just need to top up my filter. I bought some filter sand (aquaquartz) assuming it was same thing, but upon getting it in, I notice it looks different (and smaller) than what is backwashed out. Picture of what is backwashed out are attached.
My questions are:
- Are my assumptions correct that this is glass filter media?
- If it is glass, why is it bigger than the aquaquartz?
- If I want to top up my sand filter can I top it up with the aqua quartz if this is what is in it or do I need to do a full change/get the same stuff as is in it currently?
- How do I know how much to put in the sand filter to top it up?
