I dont think there are many secrets to getting good color. Managing nutrient import/export, good flow, strong lighting, regular water change schedule. IMO I think a major contributor to good color are mounting the SPS to a fixed location. Dont move them around frequently or leave them on a plug that lets them sway around from current in the tank. Its almost as if the coral knows it hasnt been mounted. Give your SPS stability and they will show you love.
I agree 100%.............no need for all those additives mentioned in other posts.
While many of my sps have gotten some nice colors back there is still something off, keeping the full potential of the colors from coming out. PO4 is 0, need to have it checked again though on a Hanna. I do run PO4 remover and carbon changed monthly. NO3 last I check a week ago was 10ppm, still higher that I would like it. The pics make the colors look twice as brown as they really are but for example my Scripps is still totally brown no purple at all. So is the coral on the far right on my frag rack, see pics. These 2 Im haveing the hardest time coloring up. I ended up loosing my Marshal Island Blue Bottle Brush, STNed for an unknown reason. I also have a small spot of STN on my Hawkins, but it is a shaded spot at the base so I think that is what is causing that. The rest of the coral is growing well and has good color, nice purple tips and the Hawkins green base. Yeah some about half of my sps look good and all my lps are happy, dont know whats up with the rest of the sps. Upgrading to a 75g soon just waiting on the tank so I hope to have better results with a larger volume of water and better lighting, adding a 2nd 250 and VHOs.
just throwing my .02 into this, what kind of reflector are you using for you 250w halide? brown acros are usually pretty straightforward causes.
1. not enough light
2. too many nutrients
3. flow
4. chemical warfare (leathers etc..)
It is not theory..... I have prof
It's hard to think you have low PO4 with that amount of bubble algae. Just because you can't measure it doesn't mean you don't have a healthy supply of it. That BA is living off it...
A couple of questions;
How long has that live rock been out of the ocean?
One of the corals looks like it has AEFW bites on it, have you tried dipping them? If so, for how long?
I have them and for the longest time couldn't understand why my corals were not coloring up, some of them didn't die they just looked tan....
I test my new buckets of salt to make sure they are goo. I use reef salts higher in alk, ca and mag so I wont need to add anything to them.do you test and buff the water before a water change? If you use the same salt every time it you can just add the same amount of chemicals every time.
Well I hope my 75g upgrade will help with that. However my 40B is very stable.Small water volumes are tuff to maintain. Being a small tank plus being a mixed reef. You got your hands full
