Agh, I just had a huge post, but when I clicked submit it said no post mode selected. Trying again :(

My friend went off to med school, and I bought his tank. It is a 125 gallon tank that had been running for years. It only had 2 fish in it at the time, a black damsel with a bit of yellow at the very end of its tail, and a ocellaris clownfish who is just as personable as can be. It had 2 powerheads, 2 returns, a wet/dry sump? with bioballs and pebble like rocks, 2 glass tube heaters and about 2 inches of crushed coral substrate. No live rock, but 1 great rock that had lots of holes, and 2 dead corals.

We took the tank down around 1pm, and had it back up and running by 6pm. We were told by 3 LFS's that by keeping the filter wet and the substrate wet, we wouldn't have to really cycle the tank. Does that sound reasonable? We also kept a few gallons of the old water for the fish during transport.

My wife picked out the following other fish:
1 adult azure damsel
1 juvi black and gold damsel
1 juvi blue reef damsel
1 juvi yellow tail damsel
1 blue and gold damsel? (more like blue and cream, not sure)
1 six lined wrasse
1 golden head goby
2 peppermint shrimp (who promptly disapeared)

We also picked up about 40 lbs of good live rock, got rid of the two dead coral pieces, probaly 20-30 lbs of builder live rock (big rock,b ut not as well grown over) and 20 lbs or so of just plain rock. We built upon the original rock and the plain rock, placing builder rock ontop to make structures, and the good live rock in places to hopefully stimulate growth across all of the rock. The rock was all cured before we purchased it (and didn't smell rotten).

We are considering getting:
1 more Ocellaris clown
1 royal gramma

later down the road, once the tank has matured, a mandarin dragonet.

I also like the sound of a Jawfish, from this quote alone:
"They will typically spit gravel at any fish that comes too near to the burrow (and even at the hobbyist who tries to get a closer look). "

We eventually want to get some coral, so I can forsee returning some of the damsels. Especially since I read they are so aggressive. So far they aren't really. The black one we got with the tank is actually quite passive. The only agressive one is the Azure. Clownie stood up to him, and he has since left him alone. The lil guys have figured out they can team up against him, and so now he just swims around, very occasionaly he will dart after one for a brief moment. No nipping at all.

What are we missing? I bought 2 4' power compact light sets, each has 2 actinic? blue and 2 regular lights in them. They overlap for about 2 feet in the middle. What about a protein skimmer?

What other things would go well for the "clean up crew" as I have read it is called. The 2 shrimp were a start, but I've read about hermit crabs, brittle starfish, and snails? Would adding "live sand" help, or is the crushed coral the same? Do we need more live rock?

Thanks for any help, this site has already been quite helpful :)

Hehe, nope :)

I think we got it into our heads we would need some damsels for a while to cycle the tank, then everyone said we wouldn't need to, but we got the damsels anyways.

We will keep the black one that came with the tank for sure. I'm all for switching out the other guys, just depends if the wifey wants to.

1. I would ditch the damsels back on the LFS, when they get older, they will be very aggressive. Some of the damsels will lose their attractive colors as they get older. Best to get rid of them now before your wife gets too attached to them(from personal experience). I don't know if you can suitably keep a jawfish with a crushed coral substrate. It may need a finer type of sand IMO.
Especially if you want passive, peaceful fish down hte road. :?
2. I would get rid of the bioballs in the sump slowly, as youe rock begins to build up nitrifying bacteria. The rock will do a better job at keeping nitrate levels low.
3. Is there enough room in the sump to put a skimmer in there? I believe that the most popular kind is the Euroreef kind. Don't have one of those, so I'm not sure.
4. Most importantly, have fun....the hard part is out of the way--->you have the tank and stand, and your wife hasn't kicked you outta the house. :lol:

BTW- How's Jax? Was stationed there in the Navy for 4 years awhile back, havent been back in like a year and a half.

Well, the blue reef damsel seems to have disappeared from last night. Wife swears she saw him this morning, but we can't find him anywhere. He isn't floating anywhere, he doesn't seem to be in the filter/overflow/stuck to any of the powerheads, No clue where he went.

Is there any problem with having both the bio balls and the live rock?

I really don't know how big a skimmer is...The filter area is about 18"hx24"wx12"d (just guessing here)

My SG was up a bit, so did a water change and it is now around 1.027-1.028. I guess I'll do a bit more tomorrow and lower it a bit.

pH is 8.2
Nitrates and ammonia don't even register on the test kit
nitrites was .2
Temp is sitting at 80 degrees (which is what the LFS said?)

As for Jax, I've lived here most of my life. I enjoy it, it is still steadily growing. With the super bowl here this year they are doing a lot to spice up downtown, or trying to at least. They finally put up that wonderwood expressway that connects right near my house to Mayport area.

Thanks again :)

40 lbs of live rock is low to support a 120 system with corals and inverts -- most sources i've seen say 1 - 1.5 lbs, but you can probably get away with less... and it depends on the porosity of the rock as well.

probably a good range for a 120 would be 100 -- 150lbs.

make sure to check out wetwebmedia.com as well -- tons of great newbie FAQs!

I added 1" of coral and 3" of medium sand and got a nice substrate that is sandy enough for anything I would want to keep, yet still has dimention. I actually got this idea from the LFS show tank that I visited.

I wouldn't get rid of the bio balls until you either have a problem with them or get better biological filtration.

I second the filtration, but with time, the crushed coral will make its way to the top of the substrate, leaving you with sand under alot of crushed coral.
