Coraline algae..

[betiuminside]

Hello,

On my rocks the Coraline algae is pealing off...

Is this normal?? Natural process or is dying?

whats your calcium (and other water parameters) test at? also check your phosphate level and the age of your bulbs.

[betiuminside]

calcium is at 460 and other parameters are good but I haven't check phosphates.. that's they only reason... maybe. My lights are 1 month old.
In a different forum they told me that it was a normal process... I will buy a phosban reactor soon...

Is it bleaching as well? My coraline algae used to peel off a little but never completely. It would peel off and start scrolling like a scrolling monti. It was pretty cool. To what lighting did you upgrade to?

This is the fixture I have

I will upgrade hopefully with in 4 months and I will need help to build my own fixture. For how much could I build a MH fixture myself? average?

I had that happen once when I accidently got my calcium really high. It grew so thick that it wouldn't stick to anything any more. It came off the glass in big sheets. I end up giving away a bunch of it to folks that were starting up new tanks to help seed their tanks. We just crunched it up into a powder and dropped it in.
