Phil, how many lbs of liverock is in your tank and what kind of lighting did you say you were using again? I can't remember if you said MH or PCs.
Oh and how often do you do water changes?
Sorry about all the questions, I am just curious. Thanks
Well lets see. I spelled out some of the parameters back on page 4, but let me give you a little more background.
This tank has been set up for about 16 years. Because of this, it is pretty stable. The current lighting is 4x65 watt PCs. Most of the liverock is the Florida live rock that was originally in the tank. Florida rock is more dense than Pacific live rock so it was normally stocked at 2lbs per gallon instead of 1lb per gallon like Pacific live rock. So, that means that I probably have about 100lbs of live rock, but it looks like I have less than 50 lbs. (Florida live rock is no longer legal. Most of it was collected from the base of causeways and wasn't very high quality)
The bottom has only a sprinkling of coral sand and in some places the bottom shows through. In a couple places the bottom is more "mud" than sand.
The small outbreak of cyano on the back is a result of my fish death. I wasn't able to find the body of my large royal gramma. The little carpet of algae on the back used to be controlled by the purple tang and the tomini tang. It only appeared since they died.
I don't do "planned" water changes. I changed water when I pulled out water to raise the baby clowns from the pair of orange skunks I used to have. I will make a water change when I think I need to remove some of the "mud" from the bottom of the tank or something like that. I might do a 5 gallon water change 3-4 times a year. When I set up a new tank I do water changes once a month for about the first 6 months. After that I just sort of read my tanks and let them tell me when I need to make a change.
The only thing I add is a two part calcium additive. I used to use the stuff from Warner Marine. Now I use C-Balance from Two Little Fishes because I can get it cheaper and see no difference in the ability to control my calcium and alkalinity.
I do not tell people that they should keep their aquariums like I do. I have to do what works for me and fits my life style and my budget. There are some things I can keep and some things that I can't. At this point, for the most part, I know what those things are, and I'm OK with that.
