Hi! I bought my son his first betta today. He's a beautiful Crowntail. We named him Luke (for Luke Skywalker). DS is a Star Wars fan. Anyway, I've read how to do full water changes in many places. But then I've also read to NEVER do full water changes.
We're keeping Luke in a 2.5 gallon tank with a filter. My first question has nothing to do with water changes...the filter is making way too many bubbles on the top of the tank. Is there something I can do to stop this? I'd like to continue to use the filter as he seems like like the current. I'd just like to slow the flow down a little bit so the bubbles don't overwhelm the tank. I noticed this before I ever put him in it. There was about a half-inch of bubbles in the tank covering the entire surface!
My second question is regarding partial water changes. Can someone walk me through how to do them? I'm sure it's easy but I want to make sure I do them properly. I've done a search here but don't see anything describing the process. I know I can leave him in there but as for the easiest way to get the water out and replace the water while leaving the temp pretty consistent (we're using a heater to keep the water around 80-degrees), etc.
Also, with the 2.5 gallon, do I need to do 25% or 50% changes and how many times a week or a month? I just keep seeing so many different answers when I do searches.
Thank you so much. This is a great forum!
