Do I need to replace this water if it’s yellow, or am I fine to keep bottom watering?

Methinks the yellow is from algae. I don’t think it’ll harm the plants at all.

I don’t see any yet, but definitely could be forming

I’d say that if you have the time, it wouldn’t hurt to change the water. I’m sure it’s fine tho
