I am a long time aquarium keeper but have less saltwater experience than freshwater. I set up a new tank a few weeks ago and have added some really good looking live rock-that is to say it seems to have a lot of nice growth of differing micro organisms. I have allowed the tank to run with only live...

If i keep on doing water changes and my tank is cycling will it set me back in steps? Because my nitrites and nitrates are off the scale! Originally posted here:  Cycling Problem

Alright so the red turd algae is getting out of hand so I’m going to rip off all of my coral off the rocks and then clean all of the rocks… Luckly most of the coral came off real nice and is sitting on the sand bed right now. So now I need to figure out how to clean this rock. This is how...

Here’s the plan…set up one of these new, sculpture like tanks with live rock and sand and stock with the 1 fish 1 loved most when I last was keeping a fish only tank (10+ years ago), a flame angel and a couple of cleaner or fire shrimp, a couple of hermit crabs and a bumble bee snail or...

The purple "algae", or at least I belive it is algea…is really covering everything and it seems to be affecting the coral. Should I be worried and/or is there something I need to do? The rest is here: Can a tank have too much purple algae?

I just set up my first saltwater tank a few days ago, i am using a beginners pH and Alk test kit from Red Sea. My pH is at about 8.2 and my alk is around 3.5-3.7 meq/L . On the Alk test kit it says that anything above 2.8 meq/L is High, but i heard that a good range is between 2.8 to 4. Should i be...
