Would you mind breaking down your maintenance schedule and amount of flow? Just curious for the sps care in a small mixed reef like that.
I'm using only a Vortech mp10es for flow. I have it set to reef crest mode at 75%, so the flow varies randomly from 200 gph up to 1,100 gallons per hour.
As for maintenance, I do the following:
1. 3 gallon water change every week (or two weeks when I'm lazy)
2. Carbon change ever two weeks (I have about 100ml in a phosban reactor)
3. Kalkwasser jug (5 gallon) refill every twelve days. I use kalkwasser for top-off.
Feeding:
1. Feed the fish pellets every day, mysis shrimp 2 to 3 times a week.
2. Feed the sps oyster feast every other day (sometimes I target feed my acros).
3. Target feed the LPS some mysis shrimp 2 to 3 times a week.
4. Target feed the sun coral mysis shrimp every other day.
5. Dose 1.0ml of Vodka/Vinegar mix daily.
I blanket feed the tank with a pinch of cyclop-eeze 2 to 3 times a week, so everyone gets a bite. The LPS and sun coral also occasionally catch the pellets I give to the fish.
Overall I've been feeding a little heavy lately, especially after I bought the sun coral. But coloration has actually improved a bit and my clean up crew--with the addition of a small fighting conch--has been able to keep up with any algae growth.
SPS in a small mixed reef isn't really that hard these days. Fine control of temperature, salinity and pH are easily achieved in a nano with rather simple technology available to hobbyists. Maintaining the levels and balance of alkalinity, calcium and magnesium has also gotten easier, especially with many high quality salt mixes and additives that are now available. Not to mention lighting and filtration equipment has come a long way.
I hope more advances come in the way of feeding equipment and products. With the rise of NPS tanks I think we'll see the development of food reactors. This has the potential to benefit more than just NPS corals. Imagine automatic feeding of high quality foods to your fish, inverts and corals.
