Flatworm eater for pico tank

[corpusse]

Flatworm exit really is a great product.

I suggest you use it and do a 300-500% water change if you are that worried about crashing.

IE double dose 100% water change, wait a few minutes 100% water change, a few more minutes another 100% water change and repeat the process until you are satisfied you've gotten all the dead ones. Doing the water changes with a turkey baster and airline tube you should be able to get them all.
