Polyp Extention or lack of.

[npsossi@msn.com]

Looking fro a little help. I have a 90 that has been up for 5 or 6 years
150 lbs live rock
2 250 watt mh Reeflux 12k
2 96 watt PC
30 gallon sump
Socks washed in bleach every 3rd day
Asm skimmer modded
Mag 1200 return
4 maxi jet 1200 modded to 2100
15 gallon water change weekly rodi IO

No3 less than 5
Po4 undetectable
Kh 12.2
Ca 400
Mg 1200

I have SPS in this tank and I get no polyp extension on any of them. I can pick up a piece at the LFS that looks like it could use a shave and I take it home and none. I am getting blues and greens in the SPS not brown. The peices are growing but I am sure hat could be better. Any Ideas on how to go about fixing this?
Thanks
Mark

I had the same problem as you, and heres what I ended up doing...

1st phase
--dosed vodka at the minimum levels, even though I wasn't detecting any p04 I was sure it was lurking somewhere in my system, i was only using 1.2 ml on my 75 and saw pretty good results.

2nd phase
began adding probidio, bio digest, bioptim, and reef booster once a week after my water changes (this is when I started to see the polyps at all in my sps was two weeks after starting this)

3rd phase
Going Completely ULNS in my aquarium. I now use mb7 and BF from Brightwell aquatics, combined with the reef booster from probidio...I will be adding the zeolith system here very soon once I get a larger sump...since using all these methods for me I have seen great PE

I have been using PO4 minus and AZNO3 for the past 2 or 3 months. I was going to switch over to MB7 and Biofuel but I was afraid of over dosing and depleting the O2 from the system. Thanks for the reply

I am very very careful with the dosing, I also go a little bit under what I should be dosing, and it seems to work out well. I believe with my next system I will use ozone to and check my orp
