update: I did a 20-30% WC (lol I don't know the exact number) to clear all the stuff. Yesterday by accident I put it in WAY too much food by accident (the bottle is not a shaker :/) and I ended up with A LOT to clean up today and a lot of poop too. There was some left over but it's not like I have to take out 100% because of that mistake hopefully.
I decided to not cut the plants because it seems like the bottom parts are brown but their green branches that grew bigger seem healthy and look like it's still growing.
On another note, I REALLY need help with using a siphon. To get it going I put my mouth on it (please tell me there's another more sanitized way) and suck on it and let it go right before the water gets to my mouth (sometimes it does
) although, I have issues getting it started sometimes with that method so I would like some help.
Also, is it safe to buy another set of 2 fish to add to the tank? If so, do I need to quarantine them? How?
