Once it is installed, you can add the gravel to the top of the resin. As soon as you backwash the system, the medias will reclassify themselve instantly. (no arguments here please, I have done this in training seminars for years with clear vessels to prove the point. All of the resin is displaced within seconds by the gravel) Add approximately 10-15 pounds of gravel on top of the resin. You will not have resin coming through the screen ever again and you will slightly increase the systems efficiency by having better bottom distribution.
Do not buy a cheap bottom screen, only a D-190, 40922, or the heavy Clack bottom screens. Their are many Chinese bottom screens that are knockoffs of the US made units that look simlar but cost 25 cents, be sure to use only the USA made or Italy made bottom screens.
