How are you doing? I hope you are having a great Monday!
Lately, I have been thinking about moving from cotton to those "blue sponges" that several of you have in your test tubes.
I found an article in AliExpress: https://www.aliexpre...0021943745311"}
Did you buy stoppers from them? If so, are you satisfied?
Also, please, I will appreciate advice if you have had bad situations using these blue sponges.
In my humble and short experience, they handle the water (and particularly bubbles, for us, the newbies) in a better way. But I'm open to your knowledge.
Thanks!
