hello, First off, I'm brand new, and this is t being posted because I want to get in this expensive hobby, but my roommate recently (idioticly) bought a 4L fish tank with a filter, ran it for a day and yesterday added four amino (spelling?) shrimp. There's a moss ball in it, silk plant, cave and gravel. She decided to drop fish pellets in there but they didn't eat it so I told her to take them out which she did, but she missed one and this morning, the water is cloudy. I've been reading and it sounds like a bacterial bloom? I took the pallet she missed out but what do I do now? Is it to be left or what? I told her to get some Tetra Safe Start as I read it's good for new tanks? Is this bloom harmful to the shrimp? Will it clear by itself? She's got two more coming next week, is it safe to add them? No yelling please, this isn't my mistake, I'm trying to fix it and not let these things die. No I can't take them back, she got them offline, no the pet shop can't have them because it's 20 miles away and we don't drive, no I don't know anyone with a fish tank who could take them, no we cannot afford a bigger tank. Sorry but people have been very VERY rude to me on other forums, I can't say it enough that this wasn't my mistake and how bloody mad I am at her for doing this without doing any research. But advice is needed. Thank you.
