Hi, The time has come for me to shut down my 100l soft coral and fish tank and live without an aquarium for a few years. I hope to make a comeback in a few years time, so I was wondering about how to best clean equipment for long-term storage. The stuff I am wondering about is: * Cooler *...

After running my 100l soft coral tank pretty much smoothly since its inception almost 5 years ago, disaster has now struck. I've been away from an extended vacation, and it seems that I overstimated the amount of time my automatic top-off system could run on its own. When I arrived a few hours...

Hi, I have just purchased a small hang-on tank (about 2 liters). I'm looking for stocking suggestions. I've been thinking of a shrimp and goby pair. If I do that, would it be possible to combine with a couple of other small crabs, or a hermit, or a small shrimp? The water flow is not very...

I was browsing my LFS today, and came across some interesting looking LED lights: ¡Ú³ÚÅ·»Ô¾ì¡Û¡ÚÁ÷ÎÁ̵ÎÁ¡Û¥«¥ß¥Ï¥¿¡¡LECOLT(¥ì¥³¥ë¥È)¡¡¥í¡¼¥¿¥¹¡§¥Ó¥ª¥È¥Ã¥×¥¸¥ã¥Ñ¥ó³ÚÅ·»Ô¾ìŹ (sorry, Japanese only) Says 280, 1300, 490 lumens for blue, white, red/blue respectively. What's the "state of the art" re...

I had a conch in my tank that has been there since I set the tank up about one and a half years ago. Yesterday, its shell was empty, and there was a hole pierced through the back of the shell. I saw it moving around normally two days ago. I'm trying to figure out how this could have happened...

I am considering getting some chaeto for my sump. It's more or less impossible to get in shops here in Tokyo, so I'm considering getting some online. How well does it ship? Would it be ok to order it now, or should I wait until the weather gets warmer? Also, will I need to take any special...

I've been having trouble with my Euphylla coral lately. Over the last few months, several branches have died. One branch has been slowly dying off lately. Yesterday, I saw that about half the polyps on this branch were gone. This morning, I found one of my hermits sitting on top of that branch...

I asked some advice regarding upgrading my 36W PC lights (60 cm tank) a while back, but never got around to buying. I currently have the choice between a 150W MH and a 70W MH (both are actinic and double-ended). What I want is basically to expand my future options a bit to perhaps include a bit...

Could someone please help me id the coral in the attachment. Thanks.

I'm thinking of replacing my CBS, who is treating the tank as his own private all-you-can-eat buffet (in the 6-7 month's I've had him, he's eaten two hermits and two small gobies). I'd like to replace him with a standard scarlet cleaning shrimp, but I'd also like to add a small peppermint...

Hi, I recently installed a chiller in my 100 liter tank+sump setup. The chiller is rated for up to 360 liter, so it should be more than big enough. Beside the fact that it is very noisy, I am getting very poor performance. It chills the water at about 0.1-0.2 degrees (centigrade) an hour, and...

I'm looking for a light upgrade for my 60 cm tank. My current light is a 36W power compact with one double-tube (10.000k/blue). The corals in my tank are: 1 Yellow polyp coral, 1 Pachyclavularia spp. (Green star coral), 1 Euphylla (torch coral) and 1 Discosoma spp. (Mushroom polyp) They seem...

Hi, I just got a Euphyllia coral for my tank (most likely a torch coral). According to my "marine invertebrates" book it likes meaty foods. Does this mean that I should feed it small chunks of shrimp or fish, and if so what size chunks are best? I have a bottle of kent zooplex, and I was...

Yesterday I saw my coral banded shrimp eating the skin left over from one of my blue-legged hermits molting. It must have really liked the taste of it, since just now I caught it snacking on a still alive one. I saw the same hermit in its shell only an hour ago, so I don't know how it lured it...

I just changed the tube on my tank's fluorescent light. It's a 36W double-tube, and the tube I had was white-white 10.000 K. The new one I got is one blue tube and one white tube. Besides significantly changing the appearance of the tank, I'm curious about what effect it will have on the...

Hi, I have a 100l/26g tank. It has a AquaC nano remora skimmer with a Maxi-Jet 900 pump set up in the sump. The amount of foam it produces is very variable, and sometimes it can go for a day or two at a time without producing any foam. The collection cup fills up to about one third after a...

Hi, I'm using Red Sea salt for my FOWLR tank. I do weekly 5 % water changes, and all the inhabitants seem to be doing fine. My current salt bag is soon running out though, so I was thinking about whether or not to try a different brand next time. I was thinking of trying Reef Crystals salt (it...

Hi, I've recently set up a 60 cm tank / 40 cm sump FOWLR tank. Its been running for around 3 weeks. Two days ago, I suddenly got a major brown algae bloom. I use normal aged tap water, and don't have access to RO/DI water. I set the tank up by using some live rock from my previous single-fish...

Hi, I've finally taken the plunge and bought a new aquarium... Its a 60 cm overflow tank with a 40 cm sump. Total water volume is about 100 liter (26 gallons). It will be a fish only with live rock tank (although I do plan to put some hermit crabs and shrimp in). (picture of the tank and sump...

I'm considering setting up a saltwater fish and live rock tank. I have limited space, so it will be a small tank. I have some freshwater practice, but I'm completely new to saltwater. The only background I have is the book "The New Marine Aquarium" as well as some reading around on various...

I've just relocated to Tokyo, and I want to set up a small aquarium here. It will probably be around 50-60 liters. My biggest concern right now is that we frequently have earthquakes here. They're usually not very big, but enough to shake the house and sometimes things will fall off shelves. In...

Hi, I'm currently cycling a small tank that has a Tetra Whisper Power Filter. The "manual" says to change the filter once a month. Perhaps I'm missing something obvious here, but isn't the filter where most of the bacteria necessary to the tank live? Wouldn't it be a very bad idea to change...
