I have a 125g 6ft tank that I would like to have plenty of water movement. I've narrowed my decision to two choices: Tunze Stream Kit TS24 or Oceans Motions 4-way with ~1/4hp external pump (~4000 gph/hr) Both options are similar in cost. The Tunze streams should be a much easier installation...

I'm considering adding a closed loop with an oceans motions to my 125g. I've seen several pictures of others CL and it seems most have the holes in the sides around the midpoint of the vertical height or even some are in the tank bottom. These configurations seem to be prone to a leak draining...

I got a 125g acrylic tank that has an acrylic hood with built in acrylic flourescent light bulb holders. It has the ability to hold 4 bulbs, the previous owner only had 2 installed. I think they are NO, but I'm not sure. Since the tank top is not euro braced, would installing 4 VHO lights in the...

I am getting a 125g tank and I wanted to verify that plumbing it to my current 75g reef tank would not cause any problems. Would increasing the system volume by 125g cause any water parameter problems?

My young Naso tang seems to be rather thin. His sides are ripped like a body builder. Should he have a bit more fat so he is just smooth looking? I feed him twice a day and give nori also. What would be a good high calorie food for a naso tang?

Last night my large emerald crab had something on his claw. At first I thought it was him eating one of my lettuce slugs, but then relaized that he wasn't holding it. Instead it was stuck on his claw and he was trying to remove it with his other claw. It looked like an aptaisia as it would...

My lettuce nudibranch laid eggs today. I saw her hanging out on a rock with her body spread funny. When I went back to look she had left and where she had been is a white spiral pattern of eggs. This pic does not show them well but with the camera I have its the best I can do. What will happen...

I currently have a 10g refug running on my 75g tank. I have a bryopsis problem and am considering either adding a larger refug or a posban reactor. Would I see an improvement in my display tank by increasing my refug size to say 30g?

Anyone have any problems with the Lights of America 6500k floodlight when used on a refug? I've had one running for 3-4 mths and the bulb burnt out. When i went to replace the buld, the plastic bulb support was burnt. I guess it just overheated. Anyone else experience this?

What water depth is a 150W HQI DE 20K light good for? Or maybe I should ask, what corals-depth will it support?

I have a spare bedroom that I'm going to convert into a fish room. I will have a 240-300g tank and 2-3 smaller tanks. I would like to run all the salt tanks on a central sump. Since I'm at the beginning stages of planning I'd like some ideas of things to avoid and things to definitly include.

Here's a pictrure of my first zoos. Beyond them being orange zoos, is there a more specific name for them?

Anyone else out there a cycling racing fan? Tour de Fance started today. I watch it every year, have since Lemond won when I was younger. Hope Armstrong wins his 6th.

This is a pic of my first hard coral. It is Montipora Digitata. It started as a very small piece that I got with a zoo frag rock. The guy I bought it from said I could have it and see if it would live in my tank since I only have 260w of PC on my 75g. I put it as high up as I could and it has...

Do any tank mfg (acrylic or glass) do FEA analysis of tanks they build? I have the ability to do it myself, but think it should be something they do for the money a large tank costs. I've seen several photos of cracks in acrylic tank top plates due to poor corner radii or overflow location...

I'm looking at my options for a larger tank ~300g. I need it for my naso tang when he gets bigger. Since there are so many sizes to choose from I though I'd ask for input. I know tangs like to swim side to side, so I'm looking at a 96" long tank. What is a good dimension for the tank width and...

I got a lettuce nudibranch to hopefully help control my bryopsis problem. How many should you have for a 75g tank?

Has anyone else broke a peice of bone off the middle outside of your foot? I did a week ago and found out yesterday I'm going to be wearing a foot brace for 6 weeks and using crutches for 4 weeks. The doc said the bone is no big deal, but the tendons need to heal and any movement before they're...

Would a 20k DE MH pendant light be a good choice for a 55g hex tank that is FOWLR? I don't remember the exact depth of the tank, but its at least 24" deep. Currently the tank has 96w of pc light which seems a bit inadequate. I wouldn't mind adding some lower light corals, but will leave the more...

Since some people experience tank crashes with a DSB, I am curious about how rapidly the crash occurs. Are there signs a crash will happen or does a crash happen overnight? I have a DSB and think I have all the correct critters. If there are signs of a pending crash I would like to know so I can...
