1 week into cycle - water change?

[ReefJuice]

Hey all,

I've just passed the 1 week mark on my 25 gallon peninsula cycle, I did a fishless start with Brightwell's QuikCycl and Microbacter Start XLM.
There's no filter sock, no activated carbon, no skimmer, no filtration. Just a lot of flow from pumps and powerheads as well as sand and rock (no light, except ambient from the rest of the room). Should I do a water change, or do I continue to let the cycle continue without any interference? Let me know.

No strong reason to do a water change now.
Also no reason that a water change now would noticeably harm or delay the cycling process.
(so it doesn't really matter.)

No water change should be done at this early stage.
