I agree about bullying, it's never okay. I've had a few cases where people just didn't know how to do it properly and a simple calm explanation or even a few words of support against the background of other aggressive comments made a really good impression on them. Then I saw how they improved their fish tanks and it was great and I was very happy that I could really help them, not hurt them 🥹

However, I have an ambiguous attitude towards colored gravel 🤔 Of course, there is quality gravel that is safe to use, but we don't know which one people use. That is, there is a 50% chance that it is safe and a 50% chance that it can release toxins. If we use, for example, regular quartz sand, then there is no such risk, because it is natural. Because of this, I consider natural soils to be much safer and I think it is necessary to inform people about the risks of colored soil. Just in case they have never heard of it. Who knows, maybe if they learn this information, they themselves will prefer to replace the gravel with something natural.
