Hi, really hoping someone can help.
We bought a Juwel Rio 125 and got it out ready to be set up on Tuesday night. This morning (Thursday), I’ve noticed the inside of the aquarium glass has white spots all over it on the inside. Looks kinda like mould, but they are really hard. Will need to be scrubbed off.
But does anyone know what this even is? Is this normal?
We are brand new to aquariums, so don’t have the first clue really.
From googling, I’ve heard sunlight can be bad for tanks and it’s in a room (dining room) that gets quite a bit of light in the mornings (nowhere else to put it) though, it’s not directly in the line of the patio doors (where the light is coming from). I assumed this would be ok and certainly not an issue for a completely empty tank.
Thanks in advance
