Ok so I took a sample of water than did my water change. Was gonna test afterwards. Well as im laying in bed I realized I forgot to test! Can I just do it tomorrow. The water is in a cup with a lid.

Didn’t even think of that lol. And love the “test same time everytime” it’s all about stability in this hobby.If the water is is covered, you should be fine. ICP tests spends a week or longer before being tested. The most important thing is to test at the same time every time. I don't see a problem.
Thank you.If the water is is covered, you should be fine. ICP tests spends a week or longer before being tested. The most important thing is to test at the same time every time. I don't see a problem.
ph is the one number I don’t chase.I’ve never really tried and compared but I’d say no. Personally I just dip my vials right in the tank. But overnight your ph will definitely change, I don’t know what else will really change. Depending on coral stocking your alk and calc can vary.
The PH shouldn't change. PH is directly related to how much CO2 and oxygen is in the water. CO2 can't get in and oxygen can't get out if the water is not being agitated.I think the only major change would be PH. Everything else should be close to the same.
