SPS question

[fritz]

Maybe I'm on drugs but it seems like bleached tissue doesn't regain its color. I have a bunch of WHITE Acros that didn't start that way. They all have great polyp extension and the new growth reflects their original colors. The old growth however remains white. Is this normal?

PH 8.3
Alk 11dkh
Calcium 400
Mg 1500
Amonia 0
nitrite 0
nitrate 0
phosphate - probably some, running phosban

I change my carbon every two weeks, 5% water change every week, 3 T5 bulbs overdriven with an icecap 660, individual icecap reflectors. I stepped down to 3 bulbs as I figured 4 was way too much light. Nothing seemed happy unless it was shaded by something. I tried lowering my photoperiod to 8 hours for a month but it didn't seem like enough so I went to 3 bulbs for 8 hours.

Bulbs are

Uri actinic
GE Starcoat
Geismann 11k

well, bleached SPS tissue should regain it's color over time.

how much time this takes is hard to say. It could take months.

The new growth will always show the best color.

Mg 1500

I would double check this number. Although there haven't been many studies to show what levels Mg becomes toxic, most people shoot for a range of 1250-1400.

that not a good answer

I checked my phosphate with salifert and it came out .25 .50 ,
someone check with an electroic tester and it came out `1.1 ,,make sure you have the right #s and you must have more then that ..just recenly you have tons of redslim in your tank ,Cyano eatting ssnails ,rememer !:biggrin:

I would double check your phosphates ,,and you where using tap water not long ago .,,you may have stuff in the rocks
