Getting back into the hobby after a few years. I building a sump from a 20 gallon long tank, never set up a sump before. Two questions. 1. How do I determine/set the minimum and maximum water levels in the sump? 2. Where is the best place to put the heater in the sump?

Looking at buying a new glass 150 gallon or a used 180 gallon acrylic that has been sitting empty in someone's basement for 2 years. I don't know much about the pros and cons of acrylic I've always had glass tanks and I'm always worried about buying used tanks. If the acrylic is damaged is it...

I'm wondering how much or how often everyone feeds their tank? I've had my tank set up for about a year now. I started out feeding twice a day flake food and a small piece of seaweed sheet for my tang in the morning and a cube of mysis in the evening every day. About 2 months ago a had a bad...

I've been looking for a moorish idol for a long time. My wife found one at our LFS and she surprised me by buying it for me for valentines day. It looked good at the store and was eating. Because my QT tank is small and I know they are very delicate fish I was worried that the stress of...

I added a bubble tip anemone to my tank yesterday. Overnight it moved down to the bottom of a rock in the back of the tank. Not a big deal except you can barley see it. It's only been in the tank for about 24 hours. Do you think it will move again? Is there any way to encourage it to move out in...

I have a Seaclone 100 skimmer. It was working fine for about 6 weeks. I emptied and cleaned the collection cup about 3 weeks ago and now I'm getting nothing at all. Bubbles in the chamber look good, but its not collecting anything. I've taken it apart and cleaned everything. Still nothing. I've...

I just started adding fish 2 weeks ago. My first fish were a watermelon goby and a tomato clown. Yesterday I added a platinum clown. The tomato started picking on him and chasing him around the tank almost as soon as I put him in. I separated the tomato from the rest of tank. Is there any way...

During the day when my lights are on the temp in my tank goes up to about 80. Overnight when only the LEDs are on it drops down to about 77. Is this normal? Is this flux in temp okay for my fish? My light is a 4 bulb T5. Blues are on 8am-8pm, whites are on 9am-5pm, lunar LEDs 8pm-6am...

My sail fin tang got a bad case of ich. I noticed it yesterday and unfortunately he was dead by morning. Now my tank is infected. My LFS highly recommended Ich-X. They said it works great and is reef safe. I'm a little skeptical because Of what I've read online. On the other hand I've read...

I have a seaclone 100 skimmer. It was working oaky for a few weeks except for some micro bubbles. Then I cleaned out the collection cup and rinsed the filter foam on the pump. Now I have micro bubbles like crazy and the skimmer is really loud. I have already been told that the seaclone is not...

I've had my tank set up for about 2 months. This is my fist saltwater tank. Wanted to say thanks to everyone, this forum has been a huge help. Started out with 50lbs of dry rock and 7lbs of live rock, just starting to get some purple and green spreading over all the rocks. I'm officially...

Does anyone have any experience with the SeaCone protein skimmer? I purchased one new from my LFS, it was recommended by the guy that works there. I understand its not the best one on the market, but the price was right. Anyway, I've had it running for about 2 weeks now and I'm getting some foam...

I just bought a coral frag from my LFS. This is my first coral. I feel dumb because I don't even remember what kind of coral the guy said it was. It came attached to a small rock disc and plug. Should I leave it attached to the plug or should I pull it off and stick it to the LR in my tank? do...

I just added a new protein skimmer to my 55 gal tank and its producing a lot of micro bubbles. Are the micro bubbles harmful to fish or other livestock or are they just ugly? It's my understanding that it will take a few weeks for the skimmer to break in and them the bubbles should go away...

I have a 55 FOWLR. I had a pair of O. Clowns but one of them suddenly died. I don't know why. Water parameters are all good, he seemed totally fine one day then the next dead. Anyway, I want to replace him. Can I add another O. Clown? Can I add another type of clown like a tomato or a maroon?

I saw this in a tank at a car dealership I tried to find out what kind of coral or anemone or whatever it is, but no one who worked there knew anything about what was in the tank. I couldn't find anything that really looked like it online or at my LFS.

I'm new to saltwater. I set up a 55 gal, had it running for about 6 weeks now. I have a dark brown layer growing mostly on top of the rocks and also on the glass. Is it Diatoms? Is it something else? Will it go away on its own? How long does it usually last? I started with 55lbs of dry rock...

I have a 55 gal tank. I'm using two 24" fluorescent fixtures each with one 18" 15 watt bulb. The bulbs are 50/50 10000k white/ lunar blue. Will that work for corals and anemones? I know T5/metal halide/LED is recommended for salt water. Is it just the higher wattage that's needed? The temp of...

I just setup my first saltwater tank. It's a 55 gal tank. Finally got it cycled and now I'm ready to start stocking it. The only thing in the tank right now are 2 green chromis, 3 blue leg hermit crabs, and a couple of snails. I really like the butterfly fish, but most are not recommended for...

I'm new to saltwater. I had a saltwater setup for years, when I moved I took it down and sold everything except for the tank and lights. I've been storing the tank in my garage for the past 5 years. Now I'm setting it up for saltwater. Starting out FOWLR, but I want to go reef in the future. I...

I'm just getting started. I have a 55 gallon tank and I'm in the process of building a custom stand. Between books, Internet, and talking to 3 different LFS guys at 2 different shops I've got an overwhelming amount of information on which filters to use. What is the best type of filtration to...
