I have a 75 gallon fish/reef tank that's been up for 6 months. I added corals for the first time about 1 month ago. Today, I came home and a lobe of my Trachophyllia open brain coral on the sand had been - it looks like - chewed off. The lobe was down to white skeleton in about a 1/2" or 1"...

My Powder Blue is growing nicely but will only eat Nori. I've tried every type of frozen food I can think of - it might pick at some occasionally but with no enthusiasm (even the types with algae in) It picks at dried algae (Julian Sprungs mixed flakes), again not enough to sustain body...

Hello, I've been trying to drill a one and one eighth inch hole in the side of a glass aquarium but everytime I get near to the end of the hole the glass begins to crack. I am using a Diamond glass hole saw (with a drill guide) and applying water for lubrication according to the manufacture. They...

Hi; I just found what appears to be an anemone...It's about an inch in diameter and sits in the sand out in the open. It is white and the tentacle tips are about 1/2" long and magenta in color. It just sits there and, when 'teased', disappears faster than a paranoid featherduster. My son swears...

If it is fully cured you can. If it doesn't smell bad it should be OK. If you have quarantine facilities you might want to think about that, since you could introduce certain bad things. "Stephen Theberge" wrote in...

Does anyone know where to order these online? http://www.melevsreef.com/pics/0504/t5.html

Hi: I have an adult queen angel for approximately a week and can not get it to eat. All the other fish in the same tank are eating just fine (red sea purple tang, demsels, clowns, cardinals). The tank also contains soft corals. He is slowly coming out more, but I get concerned when a fish...

I am lookng for a good marine and freshwater book on what fish is compatible with what fish and a problem solver guide.

I have a Fish Only-Live Rock 120 gal aquarium which only one of my tangs show signs of white spots. 3 weeks ago I started to lower the Salinity to 1.009. After carfully lowering the salinity to 1.009 so that there was no shock to the fish, I got it lowered to 1.009. Now that the salinity has...

Hi, Can I use Superbuffer dKH to reduce PH level? The PH level of my water is about 9.0. Thanks

I have a 60gal Hex tank that has sprang a leak somewhere at the bottom. What is the best way to reseal it? I was told by someone at a LFS to scrape off the old silicone and apply the new and then fill it with water. The pressure of the water would then push the silicone into the cracks. ...

Would there been any negative benefit to placing aragonite sand on top of crushed coral, about 2 inches of each in a 55 gallon aquarium that is being set up for a reef tank? Currently have about three inches of crushed coral on top of an undergravel filter, definitely getting rid of the...

About 2 months ago I upgraded the lighting on my aquarium to a Metal Halide\Power Compact combination. A few days later my tank was covered in diatom algea, hair algea, and red slime algae. I have tried everything to get rid of the algea.....but it just comes right back! My setup is...

Anyone else seen these? A LFS had 4 or 5 of there. The crabs were living inside of staghorn coral... They looked like the drilled a hole in a staghorn frag and moved inside. An interesting looking crab also. Light tan colored with one big claw and some interesting markings. Anyone know if it's...

According to what I've read, the iron content in our aquariums should be almost nil. When I lookied up what it is in the oceans, it was almost nil. (0.000006 ppm). Well here is my question for all you geology/chemist brains out there. If the earth is made up of mostly iron, should there not be...

Hi All, I just discovered an unknown fry floating around the tank. I have contained it in a net at the top of the tank. It appears to be in good health and appeared out of no where. I only just started putting fish in this tank and do not have a pair of anything that could mate. Is there any...

Hi: Just purchased a new Kent Nautilus TE in sump skimmer and am using the Rio 2100 pump Kent recommends. I can not get the unit to generate real fine bubbles. The bubbles in the skimmer are approximately 1/4" in diameter, thus it is ineffective. Does anyone have that skimmer which works well...
