I did a search and couldn't find an answer to my question. I have an ASM G3 skimmer. Currently there are no fish in my tank so the bioload is probably very light. My tank is 120gal with a 15-25 gallon sump/refuge. My skimmer has begun filling up very quickly with greenish water. Before, when I...

Do I need to remove all the fish from my main tank? I have removed the one's displaying ICH but I left in 3 others (mainly because I can't catch them) and they don't seem to have any white spots on them.

I bought a fish last week from a LFS (Power Blue tang). At the fish store they guarentee that every fish they sell is QT in their store for 15 days, so I added the fish to my tank w/o QT'ing it. Well, now that fish is covered in little white spots, which I assume is ICH. Ok, I have 1 powder...

That would be a personal preference. I chose to go with a green BTA simply because I like green better than red.

I have a BTA and it's been doing fine for almost 1 month. My tank is only 4 months old. I do have MH lighting though (6.6 WPG)

I'm running 2 MH bulbs on a 5 foot tank and the coverage is just fine for me. I can post a pic if you like. I'm using tube bulbs. The bulbs are about 14in above the water line however, the closer to the water, the less coverage you'll see.

But not always needed. But for $100 off ebay, I'd get one.

Alright.....like I said before my temp in my tank has always been 84-85 degrees after my 6 hour lighting cycle. After 2 days of testing my current fan design (below, these fans are on the back of the canopy right by the open back). My temp has dropped to 79 degrees, I waited 2 days to post...

Well, my first test is with the two top fans blowing out, and the two bottom fans blowing in. As I've stated, my temp has been hitting 84 degrees at the end of the lighting period. I'll tell you guys tomorrow what it reaches. The fans will come on 30 minutes before the lights and stay on for 1...

I'll try to test it both ways to hopefully end the dispute (at least the dispute over my open back design). I'll start this weekend and let you guys know.

Yes, I have an open back. I will have all 4 fans blowing in. 1 at each corner of the tank blowing towards the middle. I'll let you know how much my temp drops. It's roughly at 84deg at the end of my 6 hour MH cycle.

I have a large canopy (18in tall) and I need some advice on where to place my CPU fans (92mm, 4 total). I have no problem wiring these up to be place anywhere in the tank/sump but I need to know where the most effective places would be to keep the water cool. The canopy is open back. Should I...

Let's say that someone (me) is only home for 4 - 6 hours a day MAX. I've heard that you only need to run your MH for 6 hours a day to get their effect. Is this true. Do I need a longer lighting schedule? I am not housing any corals right now, but I will be in the near future.

I've had my first SW tank up and running for 2 months AC (after cycle). After my tank becomes better established I would like to add corals. As of yet I have not decided what kind of corals I would like to buy. My current inhabitants are: (1) Pink Spotted Watchman Goby - Cryptocentrus...

These fans only move about 24cfm. How many of them are you using?

CPR overflows do this if you purchase the little aqualift electric pump that they suggest at www.marinedepot.com. For 600gph, I would suggest you go here: http://www.marinedepot.com/md_viewItem.asp?idproduct=CR1513. I have this design and it works great after power outages, as long as you have...

Pretty sure....I have only bought two. I dug the "dead" crab out the trash after finding this one and after taking it apart there were no "guts" or anything. It just looked like an empty shell.

Well, I feel really stupid. Two days ago I bought a couple of emerald crabs for my tank. Well one day later I saw one of them was on it's back at the bottom of my tank so I was pretty upset, I thought I didn't aclimate them properly or my water parameters were off. So I checked EVERYTHING...

How do you introduce it into your system? Would LR introduce it? What are the proper CA/ALK levels?

I've almost completed the rough work on the canopy. I still have some touch up to do and of course painting. It will be painted black to match my stand. The design on the canopy matches my stand as well. The doors are not yet finished either. I just wanted to post some pics because I'm feeling...

I've been testing the one light I have the last few days to determine what I can expect in temp increase. My 120 gal is heating up approx 4 degrees over the 9 hours I've had the light on. This increase is happening without any fans blowing on the tank or expelling hot air from the box. The light...

I'm sort of glad that I don't need the box now. When I was building it, I was thinking to myself how nice it'd be to have a box like this to hold misc pieces of wood. Now I have one.

I appreciate your insights into cooling. I only put the lights in a box because that is how I've seen them be sold (usually it's a metal box though. If I don't need the box and you're saying I can place them directly in my canopy then I will defiantly go that route.

I have taken a picture of my tank with one of the light boxes on. I only have one done so I can only test it with one. (see picture below). You can see that it covers at least half the tank (the blocks holding it up are blocking some of the light). I picked these lights/reflectors/ballests up...

So it would seem you guys are saying to step down to a 250w kit. Meaning that I would need to buy new lights and ballasts right?
