Sea urchin Dead?

like 6 red legged crabs. 4 blue hermits. Dwarf Ceriths snails, Nassarius snail Florida Ceriths snail and a green emerald.

 

I would get a bigger clean up crew when the tank stabilizes What size tank is it?

 

36 gallon its like 10-15 dwarf snails, 10-15 florida ceriths, and 5 Nassarius. What should i add more? And what should i add that i don't have?

 

And should i add more when the diatoms go away?

 

I would actually leave your CuC right where it is. If you find you need to add in a month or so do so. But you have a decent amount already for that size tank IMO.

 

me too, I just wish my snails would clean my sand as much as they clean my glass. I really need something to turn the sand a bit. the cyano is slowly going away since i added my second 750 powerhead but not as fast as i would like it.

 

I see no benefit to changing the cuc now, the best thing for your tank and it's inhabitants is time. Trust me I have been there done that, but now we have forum to tell us to slow down.

Give it 3 more months and more experience with water chemistry.

Your tank is just outside a Nano tank size/gallon wise. Nanos and smaller tanks are known for their dramatic swings in water chemistry until established. Not everything you can test for goes into proving a tank is able to handle sensitive inverts and corals.

Once your start to see some decent purple coralline algae growth then you know you can proceed with more exotic livestock.

Stick to soft corals, hardy fish and hardy lps for a few more months.

 

ok. I have purple corailline on my spreading to most of my live rock but i guess this was a set back because the urchin was doing fine before all of this happen. But i will give it time before i will add any other sensitive fish. I just hope this urchin make it.

 

Yeah, I just wasn't sure what size tank it was. You should be fine with your current clean up crew
