Is this just part of the process??

My tanks been running for about a month
My parameters are all with good range of ideal reef conditions. This brownish dust type stuff comes up about 2 days after each water change
Until I do the next

Will this just work itself out?

I have the same thing going on with my upgrade right now. It's normal and part of the cycle/tank maturing and what we call the ugly stage.

What clean up crew do you have?
 
Okay, as long as water parameters remain good, it should eventually go away on its own. I haven't ordered a CUC for the new tank, I've just been slowly transferring a few snails and hermits over. I'll likely order a crew tonight or tomorrow.
 
Here's verbiage from Reef Cleaners website about Diatoms.

Diatoms

Almost sure to appear in a new system, diatoms are some of the most abundant organisms on earth. They usually surface in the aquarium as a brown powdery like substance, within a week or so after a tank finishes its cycle. Diatoms feed on available silicates in your system and will run their course in time. Similarly, because they feed on silicates, anytime you add new sand, rock or something plastic they can pop up.

Manual Removal: Diatoms are easily wiped from the glass with a mag float, a turkey baster or a toothbrush can access other areas of the tank. Be prepared for them to re-establish themselves quickly, they are likely to be able to resettle and have exponential growth rates.

Clean Up Crew: Ceriths, Nerites and Trochus and Astraea snails are effective at removing diatoms, as well as the algae species that usually replace them as the silicates in your system are depleted.

It can be helpful to always post your thinking of “ideal” conditions with the most current results of all 7 major players and the trend in each. You’ll have no good trend data yet as it’s so young a system, but actual levels can be helpful.

Chemistry is going to be a moving target for some months to come.

What’s nitrate and phosphate running at?
Too low and you starve the system allowing pest stuff algae’s and bacteria to take hold fast.
Water changes lower the nitrate and phosphate values directly.

Diatoms come and go in all new systems. Keeping parameters pinned for stability and ensuring trace levels of nitrate and phosphate help systems mature as fast as possible warding off more complicated stuff like Dino’s and maybe Cyano.
