View Full Version : Can I add a layer of courser sand?

I have a 180 gal that was set up beginning of May. Currently having a cyno and diatom problem on my sand and when I increase flow I get some sand being whipped around.
I am wondering if removing a layer of sand from the front of the tank and a layer of some courser sand would help stop that sand blowing problem..or just adding a layer and not removing any.
Currently have 2 MP40s and 1 Mp10 in tank. I would like to replace the MP10 with another MP40

Any Ideas?

Yes, and depending on the sand it does help. I put down a layer of Mini Reeflakes and a layer of Reeflakes. I can still turn the tank into a sandstorm but the larger grain size does help to keep the smaller in place.
