Don't worry so much about ph, it will rest where it wants to rest. It will be lower in winter than summer with windows and doors being closed and heaters running in the house. Chasing ph almost always ends up causing issues.
In terms of feeding the starfish, you can put a very small amount of food in for him to eat.
I tested the water today.
Ammonia - .25-.5 ppm
Nitrite - 0
Nitrate - 0 - 2.5 ppm
pH - 7.8
I added some pH up to try and help the pH before I read your comment. Only put in about 1/2 of what bottle called for.
How much ammonia or nitrite should I have before doing WC
and how much of a change should I do?
