I set recently set up a 125g. Great tank. If possible, I would get rid of the crushed coral as soon as possible. The cc will trap nitrates. If you put LS on top, it will sink to the bottom and the cc will rise to the top. How long have you had your tank? What's in it? What are your levels?

Ok, 3 diff. types of clowns will not get along. They will end up killing each other. The puffer and trigger will eat your crabs and snails. The flame scallops should help with nitrates. Continue to do water changes weekly until you can get rid of your crushed coral. I have the following in my tank for a cleanup crew:
15 peppermint shrimp
10 emerald crabs
2 serpent stars
cleaner shrimp
fire shrimp (but I haven't seen him in a couple days)
30 scarlet hermits
10 astrea snails
10 nass. snails
I have 100 lbs LR, 110 LS and a protein skimmer. 2 300W heaters. I don't have corals and don't know much about them yet. I'm budgetting for new lights after x-mas. The "brown knobby" star could be a chocolate chip and its not reef safe.
I don't have a purple lobster anymore. I originally started with a 29g, not reef. Same thing, I never saw him. He hid in a hole and I could only see a claw. When I moved everything over to my 125g, I left him in my 29g that became my QT. I got a six-line wrasse tonight and a sailfini tang which are in my QT. Lights are out now and I just saw my purple lobster trying to attack my six-line. Lobster is gone now.
I'm no expert but this has been my experience. I've spent alot of time on here researching things. Hope it helps.

you bet it does. The only thing i know is the star isnt a choc chip, hes fairly small and from what i can tell hes reef safe, he avoids the red general like the plague! and as far as the trigger and puffer they dont seem to bother the soft corals, so when i get tready to go to the hard corals ill probly trade them in. Im definately working on a bigger clean up crew! thanx for the help, sound slike i need to get rid of the CC. thanx Todd

don't do the mix of sand and c.c. I started out that way and you have to clean c.c. but you can't clean (syphon) sand so as soon as you have to clean the c.c.you will syphon off the sand and will have none in a few cleanings bien there and done that. just be sure to do a better job of the switch from c.c. to sand than I did anyone got an aleve? big headache r/t same. but I forgot to check in with the board first had I I wouldn't be swearing like a saylor over my mistakes lol hey how long tall deep is your 125? just wondering.

If your looking for a sand bed that denitrifies like a DSB made from say SouthdownOoliticaragonite your plan wont work very well..if your just looking to add critters to the CC then that would be fine..The problems is that over time the sand will work its way to the bottom and the CC will be back up on top.. My advice is to NOT do it...Remove the CC and add your finesugar size sand.

Good luck with the switch. I switched my 29g a few months back. It wasn't as bad as I thought BUT it was only the 29. I removed everything and put it in rubbermaid buckets, made the switch and put everything back. Have patience and a lot of time and you should be fine.

Let us know how you do. Oh by the way, I noticed you listed your wife THIRD on your list of interests. You better move her to FIRST if you want anything more for your tank!

I have a 2 inch layer of CC along with about 3 inches of varying sand ontop of the CC.. I purhcased three different grain types of sand to keep the sand from falling down into the CC..
Large grain on top of the CC
Medium grain on top of the large
Sugar sand on top of that..
The layers dont need to be more than an inch thick.. and when your done with the layers, just add your favorite looking layer to the top as an aestheical pleasure.
The tank will cycle everytime you add sand so i advise either doing it all at once, or very slowly over time..
I have never had any CC "rise to the top" of the sand bed.. unless of course the clowns are doing a fancy fanning action with their tails.. then the layers get a little mixed up. but i like the look of a substrate that is not uniform or soley one material.. remember, in the ocean there is all of the above, layers of CC, layers of different types of sand... yada yada..
