Hmm. Noticed one of my SPS has stripped a little bit underneath.
Crap pic as the lights were off so I had to use the flash, but it's the tabling acro not the alveopora
This section is completely shaded as it's directly under the LEDs, so I'm hoping it's just down to that but I've sent off a spare ATI ICP test I had knocking about just in case.
If it's high zinc in the water again I'm gonna drain the fecker down and chuck it out the window.
Annoying thing is, it's just about getting it's colour back (metallic green) from the last time I had problems with the tank. It's basing out nicely too and has good PE so hopefully nothing major.
Also... I picked up one of these. Cost me nearly £80 by the time I'd added a few packs of reagent but holy shit it's by far the best thing I've bought in a long time!!
