I have noticed my reef tank is not looking as good as it has in the past so I am making an action list of things to do for a reef tune up.

Nutrient Control  
Starting to use Prodibio again after a long hiatus. My NO3 (nitrate) is about 0.20ppm which is not bad but PO4 (phosphate) is 0.08ppm! When I used Prodibio before PO4 always stayed below the magic 0.03ppm threshold. 

Water Testing 
I got new test kits. Some of my test kits have expired so I was not certain if the results were accurate. I just got some of the newer Red Sea Pro test kits. The Red Sea Reef Foundations test kit for CA, Mg and Alk is fantastic! Accurate tests and easy to use. I also got the Red Sea Algae Control test kit for NO3 and PO4. The PO4 test seems to be very accurate and tests in the low range that is meaningful for us reef hobbyists.

Refugium
I am working on tuning up my refugium. I had a frag rack in my refugium that was essentially blocking water flow to the sandbed. The function of de-nitrification seems to have been reduced? I took the frag rack out about a week ago and the nitrate has already dropped below 1ppm!

Lighting 
My T5 bulbs are old. I am ordering new bulbs and will change them out. I am using the following T5 lamps and a row of TrueLumen Pro LED's from front to back:

UVL Super Actinic
Wavepoint Tropical Wave 6500K Daylight LED
TrueLumen Pro 12K Diamond White
Geisemann Actinic  Plus
UVL Super Actinic

I am also considering adding some more robust LEDs such as the Ecotech Marine Radion or maybe the Maxspect Mazarra. I like the TrueLumen Pro and I get about the same PPFD from one 36" strip @ 23 watts as I do from one 36" T5 @ 39 watts. A good amount less power consumption with about the same light output. The color on the 12K Diamond White strip is very crisp white.

New Cleanup Crew
I just added a bunch of reef critters. I got about 30 snails and 15 or so crabs. Astrea, Cerrith, Nassarius, Mexican Turbos for snails and Red Leg Cortez hermits along with a couple Emerald Mitrhax crabs.  These guys have done a great job on cleaning out some of the algae that has been growing in the tank.

I will post an update with some before and after shots in the coming weeks.
