I have a 120 reef tank with a Toms Rapids filter and a box in the back lip of the tank to bring water to the filter. I am getting a 90 gallon as an addition and am wondering of the pluses and minuses of having that box vs having the tank drilled with a hole in it to allow the water to flow into...

I'm looking for a wood cabinet, possibly black with matching canopy for a 120 gallon tank. 48"X24"X24" I need a new stand for it. Does anyone make it. It's an odd size I guess.

Great guess, my friend. I set a trap borrowed from a friend. It is an Engineer Goby several inches long. I can only guess that it arrived as a fertilized egg attached to a piece of coral. Thanks for your time and input.

Mystery solved. Set a trap borrowed from a friend. Don't know how but it is an Engineer Goby. Could a fertilized egg stock to a purchased coral be possible?

It pokes about a half inch of its body out of a tunnel in the sand. It is eel like but about half the diameter of a common lead pencil. It has a small mouth, one eye on each side of the head. It is black with a blue ring around the head just behind the eyes. I see about half an inch but have...

It won't let me. It hates papparazzi.

I have numerous pockets and holes in the sand, crushed coral mix at the bottom of my tank. Today, for the first time ever, I saw about half inch of a critter's head. It is black, one eye on each side of the head and had a blue ring around the head just behind the eyes. It had a tiny mouth...

May I place myself second in line?

Don't neglect to test your water at least once a week. Alkalinity, pH, calcium, salinity, nitrites, nitrates, etc.

Curious, how long does hydrogen sulfide stay in the water. Save for the fatalities, the survivors all seem well now and began to eat normally a day ago. I plan on not going to that back wall for a while but normally replace 35 gallons at a time when changing water. Thanks to all who offered...

I used a standard scraper, flat edge blade.

The gloves are rinsed in fresh water, then dried and stored in the cabinet under the tank, on the cover of the evaporation top-off tank. I doubt any pollutant would have made it onto the gloves.

I wear gloves that go past my biceps, made for aquarium use.

Nitrates are at 20 as of last night. I had done my usual 30 gallon bi-weekly change two days before the incident. Is 20 a danger level, enough to kill three healthy fish? I guess I need to leave that back wall alone and get a couple herbivores for the tank.

I am not sure. This was a back wall not the sand bed. Two days after the incident the survivors seem well but eating lightly. How long does it take hydrogen sulfide to dissipate?
