The strainer on those standard AGA kits are replaceable with something that would strain fine particles?If so,please link me.Thanks.Sorry for the dumb question and don't you dare Deanos.lol.
I think if you replaced it with something that has a finer strainer on it, it would lead ot it clogging more easily. It would probably require constant cleaning and you'd be looking at the possibility of the tank overflowing. At least thats what I think.
If you're looking to filter smaller particles, just use a filter sock in the sump so if it gets clogged, the filter sock overflows into the sump instead.
