I knows it's a stupid one!!! but I was not with it yesterday ... I added my tea and forgot to strain it and I've got a lot of thick slime today ... Not sure if bad or it's just because of the dissolved earthworm casting ? I kept the bottom 4 l in the fridge and that too has a thick slime sediment at the bottom of the bottles ? Is it safe to leave in the rdwc ? And just check the pumps ? Help needed ?
