I'm not sure I can tell you exactly how to achieve success. Mainly because your tank isn't my tank.
A 30 gallon SPS tank will need to be maintained different than my 280 gallon system.
A lot of what I do, is done to fit my schedule, living habits and what not. I can't tell you exactly what to do, because every tank is a little different. You might keep more fish than I, or less. You might have some softies in the tank, or maybe it's a BB tank (I have a DSB).
Actually I was hoping that more people who have strong SPS tanks with good coloration would jump in and offer their thoughts as well.
But, I really believe if all your levels are what we agreed to above and you can go days without cleaning the glass, water quality is not going to be your problem when trying to keep SPS.
But here is what I do to keep my water quality up.
Skimming. I'm not a fan of the light colored skimmate. I pull out a good 6-8 oz of dark (black coffee colored) skimmate a
day. I clean my skimmer out every two weeks. I seem to get better performance out of my skimmer after about 3-4 days after cleaning, so I let it go two weeks between cleanings.
Water changes.
20-25% every two weeks. or 10% every week. Shipon and remove as much detritus as you can from the sump or any place else you can during the water change.
Water clarity.
Carbon.
I run 1 cup of carbon for every 100 gallons of water. I used to run it for a few days once a week. I now change it out every week, so I'm running it continually.
Ozone.
I run ozone 4 hours a day at a ratio of about 0.2mg per gallon. So I run my 200mg red sea ozone generator at 30% when running.
PO4 control
I run rowaphos/phosban, 500ml in a reserve flow chamber. I change it out every 4-6 months. I've been doing this for about 16 months.
I run 500ml of rowaphos/phosban as a third chamber of my calcium reactor and change this out whenever I change out the reactor media.
I dose kalk to help with pH and calcium levels.
I have a 55 gallon refugium that has chaetomorpha for nutrient export. I run it on a RDS to help stabilize pH. The tank is bare bottom and I siphon out any detritus during my water changes.
I have 280 lbs of live rock and a 4.5" DSB in the main tank to take care of any nitrates. I blow off my rock work with a turkey baster once a week to get any detritus into suspension.
Depending on your bioload and how heavily you feed. You would need to do more or less water changes IMO. Also if you just can't keep the nitrates down, chances are you have too may fish.
How's that Ed?
