I think they’re bad for SPS, in that they seem to be opportunistic feeders and will bother corals. I remove them from my QT and aquariums for dang sure.

Maybe an ostrocod, if you found it on acros, and it tucked its buggy little legs into itself once you gave it a hard time?

Slow? Red Sea says no more than 10ppm change in Mg per day… although I usually add 20-30ppm at a time. Also check your salinity, could your salinity be low in either your tank or new salt mix?

So sorry to hear this @Srt4eric. It’s possible we should also worry, if we have toxic fish, about preventing carpet surfers with lids so pets don’t eat them too.

What did we figure out?

Remaining events updated. What are your suggestions for events between now and Dec 22? We could schedule the holiday potluck for Dec 10/Sat if everyone is generally ok with that. We do need someone to host it.

After all the talk about making sure tank stands are flat and level I wonder if filling the tank in a box to check for leaks might cause the leaks?

Since they are blinking colors - Did you check the error codes in the user manual? They blink certain colors for different errors.

@L/B Block How do you want to pick up the leptastrea? I can bring some DBTCs to CFM or you can swoop by Mountain View?

How are your fish doing?

Emerald crabs are the most effective - they cut the ulva loose to eat, and then set it free to drift into the filter. So for every leaf they eat, 4 end up in the filter. Provided you use filter socks… Zebrasoma tangs love ulva but not so much bristletooths or acanthurus IME. Tuxedo urchins...

If you had similar readings with your Salifert kits from your display tank (to sanity check your kit) then just email ICP analysis, they might send you a free test kit if they find their calibration was off

I had to look up “spalling” ha! Red Sea sells tubing to go with their dosing pump that is “Air resistant TPE” - they advertise it isn’t as permeable as silicone tubing so you get more reliable dosing. But platinum cured silicone? Is the idea the Pt tints the hose or does it have any other purpose?

Scary! Lucky it didn’t do major structural damage or harm too many animals.

So I kind of wonder, when the dosing pump initially pulls the solution into the tubing, how much that vacuum/pressure drop affects the the solubility. The concern is everything is dissolved in the container and then starts precipitating in the tube.

We’ll seems like there’s been a dead seal on the beach every time we go.

Did you see any green in the skeleton? On the colony that survived I cut until I couldn’t see any green in the skeleton, in case skeleton algae infestation is a thing (?)

My remaining 3 frags came out of QT and are doing ok, just starting to see a small amount of polyp extension again, but they are encrusting so that’s a good sign. In retrospect I should have fragged the other colony but then I wouldn’t have had that experiment to learn from. 50% yield is ok with...

@Srt4eric I want to hear more about your boating experiences. Where did you take your boat out?

OK I’m officially out of the running for this boat. Thanks for sharing Eric. But this got the wheels turning. We realized we need to 1) get on the Santa Cruz harbor wait list - probably wait 18 months 2) get a boat operators license (so we know how to drive it, and can get discounted insurance)...
