I think then it was defo a conch as the cone snail would have had loads of time to kill them.
Not that makes you feel any better about it, sorry.
If it's any constellation, my hermits have made off with about 8 nessarius

Thanks mate.

I reckon a conch could normally have escaped too, they can jump quite well! I reckon the stress of coming from the shop/acclimation probably weakened him and the hermits took advantage :(

Lol bloody Hermit Crabs!
My one is the bane of my tank, always messing with my Coral and now he’s started climbing my Birdsnest!

Sumped all mine after a number of snails were attacked. Seems like you needs to pick crabs or snails. Crabs also attack and kill each other, so I stick to snails and shrimps now.

I've just picked up another conch and popped him in the sump. When he's finished cleaning that up I'll swap him with the hermits. 

It's weird, I had a conch in with these hermits before and they never touched it.  Maybe they're not getting enough food or need some bigger shells to try on..? 🤷‍♂️

RW-8 completely packed in, couldn't afford a gyre just yet so in the meantime replaced it with a UK spec Jecod SOW-8. 
It's a good upgrade I think,  the pump is a fair bit smaller and the controller now remembers the power you had it in on each mode. So e.g. wave1 will go to power 1 then just changing it to constant will automatically put it back on power 8 or whatever you had it on.

Current state of the frags I managed to save from the nano:



Some STN on the AAC red planet (2nd from right) and bleaching on the centre one but it doesn't seem to be getting worse.   Under blue lights they actually look okay, and have pretty good polyp extension so feeding lots of RedSea ReefEnergy and keeping fingers firmly crossed...

Not counting any chickens just yet but a couple of my corals from the old tank have opened up.  This one in the pic was a really big nice torch with 5 heads at one point. If I can get a frag out of it I'll be well happy.

Also got maybe 10 heads of branching hammer showing some signs of life.  *D

The other pic shows the billions of copepods in the display tank  :D need a dragonet!

Found my skimmer making a weird noise and not skimming last night.  Took it apart and found a load of baby trochus snails inside the pump  lol

Sorry for the close up of my hand, but these things are tiny, about 2mm across




Also have the first few specs of purple coraline now so hopefully not too long until it settles down enough to add some new acropora.

Seems my refugium is working a bit too well,  nitrate 0, phosphate 0.01.

Assume this is the cause of what I think is the start of dinos on the sand. 



Also had further STN on the AAC 'red planet' acro  :( not sure whether to bother trying to recover them, or whether to just go and pick up a bunch of new ones



I'm going to start feeding flake as well as frozen, plus I've dimmed the 'fuge light a bit.  Hopefully that will raise it a bit with out causing too much algae.

Doser's fixed and in  8D



Still fighting dinos,  have now taken some microscope pics. I'm feeding loads of times every day and nitrate is now 5, phosphate 0.02.  Going to post on the big thread on r2r and see if anyone can identify.  These guys are really really tiny, this pic is at 1200x mag, the last lot I had could be seen easily at 100x.

Looking at your pic of the sand, how can one tell the difference between dinos and other brolwn algae?

Not easily at first,  after a while it forms slimy darker patches.  Diatoms are more golden in colour.

Seems the problem with this species of dinos is that they bury themselves in the substrate at night and when threatened, so are difficult to beat using UV, peroxide, DinoX and so on.

I found this quite interesting thread,  the posters are dosing silica to cause a diatom bloom which somehow suppresses the dinoflagellates.
https://www.reef2reef.com/threads/silica-dosing.698190/

I've ordered some sodium silicate from APC Pure so will give dosing a go when that arrives.

Interesting read, I didn't read anywhere there though (and I went right to the end of the thread) about allowing phosphate and/or nitrate to increase.
It looks like to me, the best way to avoid dinos is to not let the DT get too low on nutrients, not a problem on my tank, but I'm getting there.
