Slightly off topic but it may be something affecting te rbta. ( which was back to normal the next day)
I have some brown ....algea? Growing on my sand bed. Only on the sand bed. It's been there for weeks. In small amount. Never developed into red slime. Just gets dark brown throughout the day Ten later in the day/ evening it kinda fades slightly whether this is due to snail and crab traffic or not. I don't know. Also everytime I try to upload a pc
it says I've exceeded my quota.
