Got stuck into the sump yesterday. Cleaned and rearranged.
I removed all media and put it in buckets and the main tank. Rinsed with tank water. I washed all filter socks while doing this - I just throw them in the washing machine with no detergent and rinse.
Siphoned all the gunk out and repacked the media. I planned to leave the black bio balls out as they stop movement on the water surface which has led to mosquitos treating it as a love motel. I decided to put the black bio balls by making a cover from grate and pushing them below the water line with other media as weights.
I will increase the amount of crushed coral again as I took a lot to use in the guppy rack.
I cleaned the glass a bit from calcium build up and wound up with this.........
Cleaned

I forgot to take an after pic of the water stains cleaned up.
