I have a 2-chamber sump underneath my aquarium. Here is my question: Is there a specific chamber that I should place my pump in, and a specific chamber where I should place my protein skimmer? Currently the return water from the aquarium runs into the left chamber, where I also have my protein...

Is there a difference between iodine and iodide? Perhaps someone can clarify this for me?

The live rock instructions that came with my live rock from Liverocks.com say to add Seachem Reef Iodide every odd day. I've read that it is very easy to overdose a tank with iodine, and that it is toxic at higher levels. Since I don't have any corals as yet, do I really need to add this stuff...

OK, I've got a 90 gallon FOWLR. I've added 120 pounds of Keys Rock, and I plan on adding another 40 pounds of Gulf Rock. I removed all of the bioballs from the W/D filter and placed the 120 pounds of Keys Rock in the main tank last week. Do I need any other biological filtration for this tank...

It looks like I may have to purchase a chiller for my aquarium. I ran my Coralife Aqualight Pro lights today for 12 hours, and the temperature climbed to 84 degrees. I have a clip on fan blowing in the sump, and of course, the light fixture comes with 2 fans, but they are not cooling things...

Well, my Mag Drive 7 unexpectedly stopped working earlier today, and I need to replace it ASAP. :? I have an All-Glass Megaflow rated at 600GPH. My head height is approximately 4 feet, 3 inches. Can anyone recommend a pump that will push close to 600GPH at that head height? Thanks! P.S. When...

Today I received 80 pounds of live rock today from liverocks.com. Yippie! 8) I placed it in my tank right away - the arranging will happen later today when I get home from work. Anyway, I have some questions I was hoping to get the answers to: 1. I will be using the live rock to cycle the...

I just purchased the Coralife Aqualight Pro 48" light fixture. Can anyone recommend a power center for this fixture other than the Coralife Power Center/Wavemaker? I've heard some horror stories about the Coralife Power Center malfunctioning and causing fires, etc. :? Are there any power...

Hi everyone. I've got some live rock questions that I hope you can all help me out with. Please read on... I've been checking out www.liverocks.com and trying to decide which type of live rock to get. All of the rock looks great, but the Keys rock looks fantastic. Of course, it also costs the...

Just got my QT tank set up on Friday, and have 2 Ocellaris Clowns and a Royal Gramma Basslet swimming around in there. The Clowns appear to be adjusting well :D, while the Royal Gramma is in hiding, either behind the sponge filter or anywhere else he can find a hiding place. :( My QT tank...

I'm a little embarassed to ask this question, BUT... :oops: I currently have a FO tank - no live rock. Can I add a cleanup crew to my tank without live rock, or is the live rock the only way I will keep my cleanup crew alive?

My tank temperature has fluctuated been between 81.3 to 82 degrees for the last couple of days and seems to be on an upward trend. It's currently at 82 degrees as of a couple of minutes ago (10:20PM EST), which is frustrating as the temperature in my house is 78 degrees. I'm 20 days into cycling...

My 90 gallon tank is on day 15 of the cycle. My salinity is currently reading 26PPT. I'd like to get it to 35PPT, but I'm not sure how to go about it. Last night I removed approximately 5 gallons of tank water and replaced it with saltwater with a salinity of 35PPT, but as you can imagine this...

I would appreciate some advice with regards to the proper lighting for my 90gallon FO tank. My tank is an All-Glass, and came with a hood that has room for only 2 fluorescent lights. I have one standard fluorescent light and one actinic light in it. Can someone tell me how many watts I need per...

I purchased two 35 gallon Rubbermaid containers; one for RO/DI water storage, and the other for mixed saltwater storage. My question is this: Do I need a powerhead in both of these containers, or only for the saltwater container?

I've been reading several posts in the forums where people have lost fish due to the fish getting sucked up into the powerhead(s). Do any powerheads come with guards to prevent this? If not, any tried and true methods for covering the intake on the powerheads? :roll:

I've been cycling for 10 days now and have 6 damsels in my 90 gallon tank. I was told by my LFS to feed them 2-3 times a day, but my nitrate reading is 25 mg/l as of today, so I KNOW I have to cut back on the feeding drastically. I'm feeding the fish flake food. Just how much food should I be...

I've had my tank for a little over a week now and I cannot get the pH to climb above 7.7. On top of that the temperature seems stuck at 80.1 degrees, even after I lowered the temp on the submersible heater. I have a 90 gallon tank, with glass lids, and a canopy on top of that with glass lids. My...

Am I correct in assuming that I should NOT do a water change during the cycle? I started cycling on 4/21/05. I am doing periodic top-offs, but no water changes. What if it takes weeks for the tank to cycle? Should I do a water change at some point, or wait for the cycle to complete? :roll:

OK, here is what I'd like to ultimately have in my 90 gallon tank: Ocellaris Clownfish - can I get 2 of these, or am I playing with fire here? Coral Beauty Angelfish Bicolor Pseudochromis - 2, preferably Clown Goby or Neon Blue Goby Questions: 1. Is this too many fish or too few? 2. I do...

OK, I've got a 90 gallon tank, and I've read I should get a heater that supports 3-5 watts/gallon. Is this overkill? My LFS sold me a 200W heater (Visi Therm Stealth), but I'm thinking I may need a 300W. Any opinions?

I have purchased a 35Gallon container from Lowe's where I will be storing my RO/DI saltwater for water changes. What size heater and powerhead do I need to support this? My LFS recommended a 150Watt heater and a Maxi-Jet 600 powerhead. Is he correct, or not?

Hi folks: Specs: 90Gal SW tank 7 damsels cycling tank (down from 15 initially) Set up tank with local tap water OK, after 6 days of running just the W/D filter on my new SW tank, the LFS guy came by and turned on the UV sterilizer and my protein skimmer. After he left, I added a little Seachem...

OK, I've been doing some searching on this site regarding RO/DI units. I know I want to purchase one, but there appears to be quite a few options available. I have a 90-gallon tank being delivered today (yee haw!), and I want to provide my own water, rather than purchasing from the LFS. Here are...

Hi folks: I'm brand spanking new to SW aquariums and am looking into setting up a 75 or 90 gallon SW aquarium. I have several questions I'm hoping I can get some responses to: 1. I'm considering either a 75 or 90 gallon tank. I was leaning towards the 90 gallon, but thought it might be...
