its perfectly normal seeing the brown rusty cayno/diatoms that's the silicates dispersing from the sand . every new tank I had I always ran my fingers through the sand like a rake to help shorten that nasty stage.
circulation pumps are a must I see you have 2, I would place one on opposite ends 1 on both back rear side glass in a xriss cross direction aiming both towards rocks and the sand bed just dont aim to low or you will encounter a sand storm , I would suggest another in the center to increase flow through out the tank place it lower on back wall aiming up to give a water ripple on surface , this will also help the air gas exchange
canisters can become nitrate traps if not cleaned often and can become a pain over time . a small sump would give you more water volume and you can keep your skimmer heater ans what ever other equipment so its not a eye sore in the tank
becca asked a good question are you using RO
as tap can add nitrates that feed the brown
