Losing all color...please help

Yes it is possible. I confirmed 0 no3 and po4 many times. I still have bubble algae and some CCA. Sound like you need to add nutrients to the tank. feed a bit more and keep carbon and gfo reactor off. You have a very good skimmer, over rated for your tank and can handle a heavy bio load. If it is not skimming but foaming well them there is not much to skim out. Water is clean. Feed your fish more and get a coral food. I like Reef Roids and Oyster Feast. See if this helps and remember it will take some time to see any improvements. I run a discontinued SWC NW110 copy of a Tunze and it rocks on my system.

I feed every day a home blended mixed food of several frozen and dry fish foods mixed together with some garlic, AAs and zooplankton. I also feed nori to my tangs 2 times a week and feed my corals 2 times a week. My sps are maing a come back from high tds RO water but here are some pics.

I see you went with crushed coral, what was your thinking there? Everyone I know that has a reef (I admit are not that many people) go with live sand...what are the benefits of crushed coral?

I have lots of water flow in my tank if I went with a finer sand then it would bed a sand storm all the time. Even this CC gets moved around a bit. I ahve had a few different substrates in this tank. I was using Caribbean Sea Fiji Live at first then I went BB. After getting sick of vaccing up detritus 3-4 times a week I added in the CC.

I would love to have more flow in my tank but if I put any more in or even adjust what I have it will blow sand everywhere...also I don't like the look of bare bottom tanks but I have algae and dead spots, can you have a lot more flow than fine sand? any particular kind of CC you like?
