Here are Pictures of my Filter's, as you can see I am running an conventional pump feed setup through 3 Yamitsu Maxi Box's and a 30W UV, due to filter elevation at around 1.2m my flow rate is around 2500 gal p/h, I have a twin inlet pump inducing water from both ends of my pool, the water carried to filter then is split 50/50 into 2 seperate box's reducing the flow rate passing through each box to around 1250 gal p/h making filtration more effective in a lower energy environment, one box contains a mixture of Alpagrog, Flocor, Spindals, Foam and sponge, the other box has the UV and KI Filter Media with alpagrog underneath where the spray bar creates oxygen used for better Biological action. Then finally both box's then pass water into the third and final box where a higher flow rate of 2500 gal p/h is passed through K1 and Flocor.
