hi,
I am hoping I didn't make more of a problem than I am tring to fix.
Over the last few week I have been having a bit of an algae problem and have been detecting somewhat of a smell from the reef tank. Testing has not been very conclusive: Amonia=0, no2=0, no3=no greater than 5.
I have been atributing this smell to the filter being over come from when I clean the glass of algae, but having read more post about substrate in a reef tank I decided to change the substrate from the crushed coral that I started with to Argnoite.
So last night I removed the crushed coral from half the tank( the open half as there was very little on that side of the tank and the substrate was the deepest) and replaced it with 2" of Argonite. The other half of the tank have only about 1" of the crushed coral. I figure I'll replace that later.
So what do you think?
