Sahin I replied to your pm
Hi; I thought I'd post here rather than reply by PM as it might help someone else if they are going through same problem.
You asked:
1. Is it even enough light? Should I grab some full t5 units? I was gonna get 2 6 bulb sunpowers.
2. Why am I taking gfo out of my tank? And how much carbon do I want to run? I got some rox carbon.
3. Should I run kalk in my auto top off? (I don't even think I need to dose two part "I do but" My params hardly change). I usually do 25% water changes is this too much?
1. It is plenty of light. The issue isnt your light. Use the LED settings I provided in my previous PM. Dont use the Purpleplus setting as your main LED setting during the peak hours. - It contains a lot of red and is IMO part of the issue.
2. In a previous PM you said: Isn't working still my corals are turning brown some are white: this is the reason I said take the GFO out. Your corals are starving. Use 1/2 BRS recommended amount of ROX, then cut it to 1/4 after two weeks. This will keep the organics to a minimum and prevent a surge of algae.
3. Kalk is good if you can set it up properly to run via the topoff. If 25% w/c's take care of Alk, Ca and Mg for you along with Kalk then thats fine for now.
I would bet even if you put a Radium over your tank, I doubt you would get much improvement. Search the forums and you will see that people with Radiums even had issues colouring up SPS.
If one uses too much GFO, runs a low nutrient system and then runs intense light, the corals wont have much colour and will be pale or light brown etc.
I have seen tanks with real crappy lights etc, but the SPS corals had great colour...people concentrate on LIGHTING so much...but the reality is that food and water has so much more to do with SPS colours.
I ran a Hybrid T5/LED light unit BEFORE ATI came out with the LED Powermodule...T5/LED is a very good combo of lighting technology, I got very good results. You just need to feed the tank well, keep up on the husbandry and be patient; it can take sometimes upto 6 months or more to a dramatic change. Take photos every two weeks; compare and if you start to see results, THEN KEEP DOING that.
Hope that helps.
