My friend just recently bought an 80 gallon tank and I have been helping her with the setup/maintence and pretty much everything else. She bought a Coralife 4x96w setup that I installed in her hood for her, but after about a month, 2 of the bulbs broke, cracked the little glass piece at the...

I'm trying to decide whether to add a pair of clarkiis or true percs to my tank. I like the color of the percs better but the shape of the clarkiis. so my final deciding factor is going to be behavior. are clarkiis agressive towards other fish?? ive had percs in another tank before and they...

i wanna try to DIY a fuge to hang on to my sump, not real sure how to do it tho. it will be for the hawaiin macro algea that my yellow tang loves. it has to free flow in the water, so i cant figure out a way to design it so the algea doesnt just flow back into the sump. any ideas or designs...

We are having a little trouble with the u tube on our overflow. We are having to suck air out of it like every couple of weeks now. i relly dont know where the air is coming from, but it builds up and restricts the flow and causes the water to raise in the tank. This isnt normal is it? how...

we have a 20gal long that house a soon to be breeding pair of perc clowns. at the moment we have a fixture with 3 20 watt bulbs of NO lighting that we got for free. we have decided that we would also like to put some frags in there that we no longer have room for in our frag tank. do you guys...

I have read the other threads on Coral Banded Shrimp but still have my question. I won a very small CBS in a raffle at my local Marine Aquarium Club, but didnt want to put it in my main tank for fear it harm my livestock in there, so i placed it in my sump. I have rock in there so it seems to...

I just added a maxi jet 1200 to my 60 gal, and all my coral look like they are getting blown around. all my coral were out and seemed happy, but I didn't think I had enough flow through my tank because of ditritus and junk covering my rocks and sand. will the coral get used to this extra flow...

besides the ends, what are the differences in the bulbs. i was told that the HQI's were actually brighter or something. i was planning on getting 2 400w moguls but now i can get 2 250 w HQI for just about wholesale. any thoughts or comments? thanks

What do you guys think? I live pretty close to the beach here in So Cal and would probably be cheaper to get water from the ocean to do vigerous water changes. would using it be ok just to cure LR. i dont want to risk it in my main tank, but as long as i heat it and skim and such for curing...

Has anyone here been successful coral farming? My girlfriend and I are interested in setting one up and are trying to gather all the info we can on duing it right. any help or experiences would be greatly appreciated.

Living in California and having the chance of earthquakes, i was told that i should be worried with glass tanks breaking in one. should i really be worried about it? will an acrylic tank withstand an earthquake where a glass won't? I want to upgrade and was planing on getta glass tank, should...

I recently went to a club meeting in my local area and got to hear Bob Fenner (author of The conscientious Marine aquarist and Reef invertebrates for those who don't know him) speak. one thing he said that kind of surprised me was that we should be changing out a portion of our LR every year...

i know you dont want a lot of surface movement so CO2 stays in the tank, but what mid level? do you still want some movement throughout the plants? if so how many gph? i just have a lot of algae growth in our 20 gal and think its being caused by little water movement. i have small a HOB...

I can't figure out why my mushrooms wont open up. They were huge and beautiful when I first got them. but they havnt opened up for over a month now. all my other mushrooms are fine. the last pic is of the closed shrooms, the other two of other shrooms in my tank that are doing well. any one...

I'm in the middle of planning out everything I need for a 150 gal Reef. I pretty know everything I need, but don't really understand how metal halides work. I looked at the new bulb compairison page (great idea btw :wink: ) and really like the way the 2x250 20k bulbs look...

I have a 60 gal reef setup, and am trying to figure out a good flow rate. i have two pre drilled holes, one for out 1", and one for in 1/2". right now i have about 700 gal per hour, which the 1" hose isn't handling and is creating syphons and sucking in air and making lots of noise. the...

What kind of lighting would suit a 10 gal frag tank. We are not looking to spend a lot of money, but want to be able to raise frags. We looked at our lfs and found a 17" PC but it was only 18 watts. Any ideas? how many watts would we need for a 10 gal? thanks for your help.

What's causing these bubbles? Anyone have this problem or know how to fix it?

Does anyone know how to quiet down the air rushing into the hole at the top of the durso standpipe. ive tried a few different things, but it is just so loud. The day i installed it, it magically got quiet, but now has a tremendous amount of air rush. any tips? thanks

i got a quiet one pump not too long ago and installed it on my established aquarium to replace a dieing pump and get more flow. when i first set it up it ran beautifully. really quiet and nice flow. well i took on a little project this weekend to replace my pvc plumbing to vinyl tubing, and...

I've been reading the explanations on building overflows and have started building one myself, but have a few questions. What do you use to drill the holes in the acrylic for the bulk heads? When referring to a 3/4" pipe for the return, is that inner or outer diameter? How do you cut the...

When DIYing an overflow, does it matter how big the box is? or just the pipe that goes into the sump? Im doing two overflows, one for a 55 and another for a 25. for the 25 i wanted to to have a 4x4x4 inch boxes and for the 55 8x4x4 inch. will these be large enough if i drilled the...

i was reading some posts on pumps and have a similar question. right now i have a rio 2100 for a 60 gal tank with about 4 feet of piping. recently the pump started crapping out on me after only about 6 months of use, and there is little movement and my corals look like they are suffering. i...
