Why are they bleaching?

Here is a pic Water quality is good , What do they eat?

 

When you say "Water quality is good" what are the #'s and what are you testing? What kind of lights do you have, how old are the bulbs, how long in the tank, and where in the tank are they? They eat phto-mine like cycopleze-everything loves that stuff.

 

sorry-phytoplankton

 

tank spec's under pic,
water quality Ph 8.2, Sp GRa 1.023, Amon 0, Alk 4.5 meq/l, cal 475ppm, nitrite 0.0 ,nitrate 0 , phos 0 , temp 78.8
bulbs are new

 

gotcha-sorry I did not see that. Were they under MH before? I have never had luck with with fastest kits, I use Salifert JMHO. Where in the tank is it placed and what kind of flow?

May want to raise Specific Gravity to at least 1.025.

 

Picked them up At lfs 3 weeks ago, Don,t recall if they were in a tank w/ MH, Don't think so.
I will raise my specific gravity slowley.
when I got them i put them up high after they bleached I moved them to mid level
