As for the sand I have about half silicate and half aragonite sand. The silicate is pool filter sand and the aragonite is sand out of the tanks at the LFS
I have plenty of flow, I've got an xP1, the skimmer, and I've got an aquaclear 70 PH. Ever since I've put it in there I've started seeing dunes forming.
My tap water could or could not have a problem with algea. We will see. That just has to do with where I am located and what is in the water.
This isn't that expensive of a hobby. It's more fun than anything.
Allready checked the hydro. Reads perfect.
Angelscrx was saying that tap water has too much chlorine in the water and thats why its not good...Well chlorine is probobly the least imported additive to the water. Silicate in tap water is what causes algea growth. Chlorine and chloramine can be dealt with rather simply.
Anywho, I will get an RO
unit in the future when I set up my big tank. No biggy.
Mike your tank looks awesome btw.
