Should I do water change?

Hello, this morning I found out that my convicts had spawned I am thinking this morning, although possibly yesterday. Tommorrow is the scheduled day for water change. This tank is close to cycling, I used Tetra safestart at the beginning when I set it up. The parameters on the tank is ammonia .25, nitrites .25 and nitrates 10, using api master test kti. Last water change was done on 8/15 of 40% with a good vacuuming of the gravel on the last wc. Will it be okay with carrying out the planned wc or should I wait? This is my first experience with having a spawn.

I would do the water change rather than risk the fish health. Don't touch the substrate, just syphon out the water from the top and replace it.

If this is the convict's first spawn, even this might disturb them. But having spawned once, they will again, frequently I would expect.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Thanks Byron, that was what I was thinking of doing, I cleaned the gravel really well on the last change, so not too worried about that. This is thier first spawn in my tank, but they had actually spawned at the LFS before I got them, the fry was just over a month old when I got the pair. I am planning on matching the water that I am refilling with to that in the tank, and also making sure that I add the new water slowly. Just wanted to check and see what others thought. Had it finished cycling completly I wouldn't be as concerned waiting a few extra days, but even with tetra safestart I have found it takes a couple of weeks for everything to sort itself out.
