About 7 months ago I had 20 tons of mason sand hauled in for my indoor arena sized 170x70. We have kept it maintained well (watering, dragging etc). This past week I have noticed that the sand seems 'packed' down so much despite me also raking it last week. I do not consider it heavily used. On average I would guess 3 hours per day and maybe 3 horses, some days more, some days less. I feel like this is WAY too soon to need to replace footing, but this is also my first arena. Any suggestions? Would I just add sand to it or do I need to re-foot completely? This has just really caught me off guard and need to start setting money aside to make changes if necessary.
To describe further, it seems as if there isnt much 'fluff' to it. Any help is greatly appreciated!
