Tank 3 has alot of baby snails. the filter is broken and a guy is coing to fix it. while the little baby snails are waiting they must live   in about a quarter of the water they should have. in the picture you can see where they live and how much water they and should have.

I cleaned the tank. I used a scruby brush thingy and cleaned all the grime off it.Tank 3 is supposed to get fixed and because nothing is in it is has so much salt. the salinity level was 0. Nitrite was Oppm. Nitrate was Oppm, and the ph level was 7.7
