Tank is in progress, I spent some time yesterday and sealed concrete with concrete sealer, This stuff dries pretty quick, I did 5 coats until I don't see any pores anymore and it feels smooth, I filled clear silicone in all the openings on the floor so that water won't be able to go in if there is any spillage, specially under steel plates. This weekend I am going to put sump under the tank, and start adding rock and water to start cycling the rock.
