aly_starhs Low-Tech Planted Shrimp Tank Pico

First I'm a bit curious about cat liter idea?? I saw that it didn't work out but i'm a bit curious where that idea came from.

Just a little advice for the future. A black/ dark brown plant will never restore its injured parts. Its sort of like adding a bunch of dead fish to your tank, the matter will continue to break down and muck up the conditions water. This is most likely what killed the shrimp, they are even more sensitive to water conditions compared to most fish. If plants start to die off remove all the discolored leaves. If your lucky the roots will have enough stored energy and new growth will occur. I had some Brazilian Swordtails that got carpeted with cynobacteria (looks like carpet of algae) and ALL the leaves browned. I cut them ALL off and just left the stems at the bottoms and the larger ones actually pulled through and I still have them today after 4 years.

Also you want to be really careful about bleaching a tank. It seems more than likely the plant matter is what killed off the shrimp so bleaching was unnecessary. The bleach can linger in the sealant and kill fish, so make sure never to use it on any porous objects.
