Full view of my sump area, where most of the filtration system is. I tried to neaten things up a little. The box on the right foreground contains all the test kits I use for water parameters - phosphate, calcium, dKh, nitrate and pH. The box on the left contains additives - calcium hydroxide, strontium and home-made buffer consisting of 50% sodium bicarbonate.
