I have purple algae all over the sand
it is in casing it. I added 2 power heads to the tank to move water around but it isnt doing enough. What are some good fish or invertabrates for a 95 that would clean up the bottom.
Oh i have some snails but they only clean the glass
Sounds like cyano bacteria. A quick fix is a chemical treatment called "chemi clean". It works great, but you need to find the root of the problem. Its usually caused by overfeeding, or by overstocking the tank.
