There was everything in there from fresh water black gravel(which is still in there) to a hammer and screw driver to q-tips, measuring cups, an air pump, dosing chemicals(still sealed thank god) to everything else in the area.
I think I dodged the bullet and all levels seem to be good except SG which is now at 1.024 and it's normally at 1.025. Looks like when stuff was put in it just redirected water flow and stirred a lot up. It's clearing up slowly. Already had to empty the skimmer cup once, clean the skimmer bubble trap and in few going to clean the filter sponge.
I do have a BRS screen top but haven't been using it for the past year since all I have fish wise is just a blue/green Mandrin. Looks like it's going back on. Lesson learned now.
