whats happening to my color / polyp ext.

[KevinK]

nk background:

tank mesures 65x36 x30 deep,

about 1inch sugar fine sand on bottom and all live rock.

tank is next month 1 year (used LR and LS from old tank)

tank at this time has 4x 150W phounix + 2x 54 10.000K + 2x 54W act.

on the back of the tank I have a filter room, including a DIY 8 x 60 inch skimmer in a 65 gal sump, from there water flows in a 55 gal spare tank with about 6 inches of live sand, a 4 inch reactor with NP BIO PELLETS., skim is dark Broun, about 1.5 gal - week

from the 55 gal tank it flows back in the main tank., this loop runs about 600GH

in the display tank I run 7x Hydor kor. (3 and 4)

+ a sea swirl on a 600GH pump.


entire system is running like this for a year now, no proublems (only that I might try 4x 250 watt phounix in the future (everything is growing fine at this time, however dont know how much more benefit the 250 will be.

only thing I changed 2 weeks ago is the skimmer nek (had a 3 inch, and went to 5.5 inch)

all parameters are at 0 ore at undetectable.

KH = 9.5
MG 1300 - 1380
CA 430 - 450
N02 - 0
NO3 - 0
PHOS - 0,02


tank has mix of LPS, SPS and a few big mushrooms

fish load is very small ( 3x tang, 5x cloun, 2x fire fish)

I feed grinded mix sea foot from superstore + nori

under my profile there are some picÈs of the tank

I will try to measure for stray volt.
