yep-changed the GFO as soon as I got home - retest tomorrow. The bottom of that coral may have not gotten any light as I had put it into a hole in the rock - until I decided to glue it, due to my issues with SPS lately - so that may be why the bottom was white.

I wouldnt be to concerned with the no3 or po4. I dose them in my tank and I try to keep my nitrate in the 5-10 and phos at .008 if it goes a little higher I dont care. My sps seem to like it growing and keeping color. Dont let it bottom out or you will probably be attacked with Dinos

.008 vs .27 on phosphates is more than a little difference. I think .27 is too high. I agree on not letting it bottom out though. Not worried about the No3 being 2-4 as that seems acceptable. Watched the tank for an hour last night - no fish picking on coral , but nipping at rock = normal. Maybe the Birdsnest ( picture) was having issues with necrosis and got some algae on it and that is what made the fish nip- "bite marks". Still unsure of why I am losing SPS/acro corals - unbalanced Po4 to ALk has been suggested = as I have lower Alk ( 8.0) but high Po4. Did read that the Zoas/palys, etc. can give off toxins that hurt other types of corals. So hmmm...

Edit : 1 pm Friday Retested today using Hanna ultra low phosphate after 16 hour of running new Gfo = .15

Ca+ = 400 with a new Salifert kit.

Ok... Update.. I stopped using the Gfo for a day as the phosphate was dropping too fast. Retested po4 at 8 pm last night , 24 hours with no Gfo, an hour after feeding and it was .176. So, I restarted Gfo last night at midnight ...

Tests today 2:30 PM

Po4= 45= .138
ALK= 130= 7.28
Ca+ = 400
No3 = 4-8

Pic is an attempt to show some polyp extension... yeah

So, guess I will stop running GFO again for a 24 hour period. 15-20 gallon water change today as well.

I continue to loose LEAR frags ... they are slowly bleaching white . I cant get NO3 or PO4 down slowly. They continue to be way above my old levels : in the past week my parameters are: No3= 4-8, and PO4 =.132-.153, ALk= 8.0-8.3 DKH , Ca+ 400-410. SO guess I will just start doing 10-15 gallon water changes every other day - run both Carbon and GFO switching it out once a week, and go back to filter socks. Dose calcium chloride and soda ash or Kalkwasser solution to got to my old parameters. I figure I have already lost all the LEAR frags anyhow -so going slowly is a mute point now. Hopefully returning to Low No3 (under 1) and low Po4 ( under .1) and medium/high ALK (8-10) with ca+= 450 - which is what I always had good luck with until this past fall. I just cant figure out what changed so my No3/Po4 got so high and wont come down. If this does not produce results than I am out of sps/acros all together and will have a Zoa/LPS/fish/clams/etc. tank with no SPS as the frustration is now past tolerance levels.

Reefbreeder 24 light starts up at 8 am and ramps up to the 75% around noon then ramp down slowly to 10% by 8 Pm - blues only on till 10 PM for viewing pleasure. XR30 Gen3 on other side also starting on up at 8 AM peak at noon at 73% and down to 10 % by 8 Pm with blues on again till 10 Pm. Have both the LED's running more blue/purple to peak at 100% with white at 50% and the red/greens at about 35%. Going by Memory on specifics colors and % - but I am pretty close. Also have T5 blue/purple bulbs running across the front of tank angling toward the middle of tank to reduce shadows from LED's that come on at 10 am and off at 6pm.

The lighting should be sufficient to support higher nutrient tank I would think. How about turbulence and flow?

About 2500 GPH from sump downstairs split up into several sprayers , A MP40 on one side ramp up /down mode and the Jeboa smaller wave pump as well on/off every 5 seconds. I may pull the Jaboa pump as maybe it is putting a toxin or a trace current into the system?? grasping at straws now?
