Cut away the necrotic areas and frag it into 4 or 5 pieces. It's a shame since it's fairly large but the dead areas will continue unless you cut them out.
I tried 7 and had 7 for quite a few years. Then they started to decline. I'm beginning to wonder if they require larger tanks that what is commonly believed.
I'm actually shocked at this. The Amphipods do have the ability to cleanse their system by storing toxins in their exoskeleton but I have no ability to understand how the polychaete survived.
If you find a snail then I'd have to say the product you thought had copper in it doesn't or it's so...
Hmmmm, I'm not sure hair algae is considered a macro algae. In my experience macro algae will outcompete micro algae if it has good waterflow and adequate lighting.
I've maintained a couple dozen systems without skimmers.
Funny how someone that crashes their tank needs a scapegoat. Human nature I suppose.
That said, having a skimmer provides a much larger margin of error when things go wrong.
Yep, I agree. Although the marine epoxy doesn't stick to the rock well it will form a good cradle that will keep the structure stable. Just be sure you use more than you think it should need.
The white will quickly be covered by coraline or coral.
Two thing I just read on Amazon that worry me:
1 - "Lexel should not be used in areas of continuous submersion (i.e., aquariums or swimming pools)."
2 - "Resists mildew in damp environments"
But the bacteria in the skimmate comes from the tank so I don't think adding skimmate back to the tank would increase diversity. Perhaps skimmate from someone else's tank?
