I'm gradually replacing my crushed coral substrate with sand and placing some live rock in my tank (also gradual). Is there anything I need to be aware of as far as chemical parameters, lighting, etc. to make sure my live rock and sand stay 'live' and beneficial for my tank? I'm running a...

OK, this is sounding good then. From what I've calculated, I need 105 lbs of sand to do a 3" depth. I've got 30 now (which I just rinsed and have waiting in buckets). So I figure I'll do about 1/4 of the tank at a time, probably weekly like you said. So I'll get 120 lbs in there total, which...

I'm going to change out the crushed coral for sand in my 75g tank. I'm also trying to add some live rock in there, but this question is about the sand. I am SO over the cc. I read that I can do it gradually by taking some of the cc out and putting sand in, then taking out more cc and putting...

I'm considering changing from a 75 gallon to a nano tank. I just have 2 clown fish so I don't think it would be too hard to do that. I'd like to have some live rock and maybe some corals. I realize I need to watch a smaller tank closer as things go downhill faster, but I'd like to move the...

Kind of weird, huh? Usually my nitrates are around 20, which is basically what's in my tap water that I use. (I know I need a RO/DI, but can't get one yet.) I did a 10 gallon WC in my 75 gal. tank yesterday afternoon and when I tested the water today, my nitrates are much higher. The nitrate...

After much reading, most people seem to like the AquaC skimmers, so that's what I'm looking at - unless somebody has a better idea. :D I'd like one that goes in my wet/dry sump (praying it will fit and I'll have room to get the collection cup out), so I'm looking at the AquaC Urchin. I think I...

Yeah, and there's also the fact that I don't have a QT tank. I don't have the space or the $ to set up another tank right now. I'd need a full set up with light, filter, etc. on it, correct? I'd also have to completely dismantle the tank to get him out of there. He would not surrender...

Also, our LFS said they would order fish for us if we want something specific. We haven't tried this so I don't know how it would work if the fish came in unhealthy or whatever. But I figure they're getting a break on their shipping already for their large orders, so I might as well let them...

Well, it's about that time...I'm itching to add another fish. However, after adding our last fish, the powder brown/white-face tang, I read that this should be the last fish you add as they are so sensitive to changes in their environment. Nice. LFS didn't mention that part and I'm pretty...

Yup, yup, had the same thing happen with mine. I got some turbo and trochus at the same time and they were all in a big ball for quite awhile. They seemed to be in a tug of war for a bit, with one dragging a couple others around. Eventually they all detached themselves. Once in awhile they'd...

You're supposed to tell me he'll be fine. :) But, okay, if you insist...tested today and the numbers were: temp: 76 sg: 1.023 (I usually have it at 1.0225, but I may have raised it a bit when I changed water last weekend - plus it needs a top off) nitrate: 20 (this has been our norm since...

He seems to be swimming straight. He looks totally healthy. His color is normal, nothing wrong with him that I can see. If I hadn't seen him laying on the rock, I'd never have thought twice about him because he looks and is acting completely normal - other than the rock laying thing. He...

Clownfish mating? Added observations/questions: I've been suspecting that the fish were getting ready to mate. The female has been checking out the inside of the barnacle and she's never gone there before. I wondered if she was checking out a place to lay eggs or something. We now see...

I have a mated pair of perculas. The smaller (male) has been laying on top of a lava rock today. This is the first time I've seen him do it, but my husband says he saw him doing this a couple of weeks ago. He's seemed fine, he's eating, etc. But he keeps going back to the rock, swimming in...

Oops - posted the 'before' picture twice. :oops: Here is the pic from this morning - the 'after' picture. Jodi

Thanks for the quick replies! Well, from what you're saying it looks like the water change I did last night *enter pats on the back here* was a good idea after scraping off...oh, probably 2/3 of the green algae from the glass. There is still PLENTY all over everything else, so I don't think I...

I have a powder brown tang. We've had it since November and it's done very well. It's a big eater and besides flake food, it picks at the algae on the coral and substrate (although it hasn't really made a dent in controlling the algae). I think he'd like dried seaweed, but I haven't tried it...

Thanks everyone for the suggestions! And hello to all the fellow Iowans! Who knew this was such a hotbed of marine activity, land-locked as we are. But maybe that's the reason. :) I'm in the DM area, in case you were wondering. And now we get to the crux of my LR issue. It's the...

I hesitate to call my tank 'established', but it is nearly 6 months old. Does that count? You can see our tank stats in my signature. I have a question about adding some live rock to my tank. I am having live rock envy. I want that neat color and the cool critters. But is this a bad idea...

Hi all! I think this is my first time posting although I've been hanging around for a little while. My tank is almost 6 months old. I currently have 3 fish and some snails (see my signature for the full tank stats). I've got quite a bit of green (non-hairy) algae on the glass, substrate...
