First, the essentials: 125gal mixed reef with ~180lbs live rock, 30lbs of which are in the wet/dry filter as rubble. Sg 1.026, pH 8.4, Nitrites 0, Ammonia 0, Nitrates 1, Ca 440-460 (I hate Ca tests!), KH/Alkalinity 8.6/3.09 (Salifert tests). I've had this tank set up for about 2.5-3 years...

I always hear people talking about using super glue to place corals in their tank. I have some zoos on a rock that my CUC keeps knocking off their perch. I would like to glue that rock onto my LR. What kind of super glue is it that you use? Can you do it right in your display tank?

I've gone ahead and purchased Selcon and Garlic. From what I've read here, it seems the way to go. I read the package directions, but am curious as to the methods you fine people employ. How long a soak? How much do you use? Always get good ideas from you folks!

I think I've misunderstood a couple of things I've read, and I think I need more flow in my tank. Right now, I have two pumps, rated 500gph and 350gph, coming from my wet/dry filter (minus bioballs!), and a 350Mag canister filter (without any media except for a bag of Purigen.) My tank is a...

Well, I want to add a refugium, but I'm not sure if I should, or how I should. I have a 125g, with ~170lbs LR, ~70lbs LS, a Mag 350 filter, and a wet-dry trickle filter with two return pumps (one a 350 and the other a 500.) I also have an AquaRemora HOB skimmer. The wet-dry filter runs...

I've been testing my water weekly, so this happened within the last week. Normally, my tests show no ammonia or nitrite, my nitrates around 15, and my pH around 8.2. Last week, I upgraded my RO to an RO/DI unit, and have been using that for topoffs and my PWCs. This evening when I tested, my...

I have a 125g FOWLR tank, with ~170lbs LR in the tank and wet/dry filter/sump, and ~65lbs LS. It is inhabited by 1 lawnmower blenny (eating well & getting fatter!), 1 Fridman's dottyback, 1 coral beauty, 1 yellow tang, 4 green chromis, 1 sandsifting star, and 1 brittle star, along with various...

I believe I understand the limited capabilities of having fish in my 10g tank. However, I know me. As a relative virgin to reefkeeping, I know I should start slow, i.e., sticking to mushrooms and the easier soft corals and such. That still leaves a wide open door though, and I don't want to...

So I had this 10 gal tank that used to house a beloved fish (which ultimately ended up in a 125g-FOWLR tank downstairs) that was empty save for the cleanup crew. I was keeping up with the water changes and testing, mostly because I still had a few snails (mostly astrea,) one red-legged hermit...

I'm in the process of changing out my bioballs to LR rubble. The live rock is curing now. The bioballs sit on an eggcrate where the water trickles through it. When I put the LR rubble in, does it also sit on the egg crate, with the water trickling through, or should it be sitting in the water...

Everyone always talks about hitchhikers on their live rock. How long does it take before these guys show up? Like polyps or other bonus good guys? Am I just unlucky? or impatient?

Both my DP-650's started functioning badly today, so I took them apart, cleaned them and checked the impellers. Everything seemed fine after that, but now, they don't start up at all. After searching and googling, I discovered that these pumps were prone to this problem of hard-restarting...

I've been following the threads for changing CC substrate over to sand, and have grown a bit confused. There are several grades of sand out there, as well as the HD stuff. Most of these sand particles are fine, <.5mm-1mm,correct--give or take a mm or two? My CC is more like gravel, which I...

I posted this question before, but I think it got lost in another thread..... Anyway, I'm back, and nearly fully recovered from surgery, so I've been working on the 125g tank which I bought, second-hand, approximately six weeks ago. I've added more LR to it, and that LR now totals ~140lbs. Is...

I have a light with three different lighting settings that are on timers. One setting is daylight; one is a neon-type of light, probably for evening or night; and the third is a set of 6 LEDs, to emulate moonlight. My question is the timing..... How long should each setting be? Should the...

I'm trying to start up a 125gal FOWLR tank, which I bought second-hand. I bought it because I have a little puffer (PuffDaddy) and a chocolate chip starfish (Anonymous) because I was one of those people who didn't do ENOUGH reading and got the puffer because the lfs told me it would stay...

I have a small porcupine puffer ( 2-1/4") that will only eat live goldfish. I know that's not good. I've been trying to feed him the frozen brine shrimp, but he just watches the stuff go by and ignores virtually all of it. He won't even eat a dead goldfish, just the live ones. I tried live...
