I have tried glacial acetic acid and hydrochloric acid diluted to less than 1 normal but these treatments didn't work. Maybe I need to soak the glass longer to get what I assume is a calcium salt dissolved. I have not tried C L R. I think one of my grad students has some that I can try...

Hi all, I have a glass plate that I use as an aquarium tank lid. I had it cut to fit my tank and it is supported by the inner lip of the tank walls. This places the lid approximately three quarters of an inch above the water surface. Over the years, a white haze of deposits has accumulated...

Thank you for all the replies! The scheduled power outage has been pushed back a week. I am most grateful that this has happened as it gives me more time to prepare. In retrospect, I should have been prepared for this, especially considering that I have thousands of dollars invested in the...

Hi all, Tomorrow night the power will be shut off in my office for 8 hours due to construction in a neighboring laboratory. The problem is that my saltwater tank is housed there. I am worried that this will have a serious negative effect on my fish and corals due to lack of water circulation...

I have found that cyanobacteria and green hair algae are extremely dependent on aquarium lighting. Within the first 6 months of setting up my tank, I experienced both of these nuisances. I found that if I kept the aquarium lighting off for two solid days that both green hair algae and...

I have a 40 gallon tank that has been running for over 2 years now. At about 4 months in, I had problems with cyanobacteria. Much advice was given concerning tank parameters including flow rates, nitrates, phosphates, feeding and lighting. I found that cyanobacteria could be completely...

I am not sure exactly how to attach images so I hope this works. This is the anemone one hour after the lights came on. Yoss 

I will try to get a picture of it posted today. One of my colleagues has an iPhone and I think its camera will take a suitable picture. My aquarium is in my laboratory's office so if I can't get a good picture with the iPhone, I will have to bring a camera in from home. I have tried feeding it...

Hi all, I purchased what was sold as a bubble tip anemone (BTA) from SWF.com well over a year ago. Its tentacles have always been elongated and far from bubbled in appearance, which I understand is normal for some BTAs. The problem that I am having is with growth. Since its introduction into...

I have used Instant Ocean and Instant Ocean's Reef Crystals in my tank. Both mixes have always been consistent in giving a pH of 8.2 to 8.3. I am unsure why some see variations in pH using these mixes. I suspect that it is likely a preparation, aeration or measurement error. Are you guys...

Cyano is extremely sensitive to the absence light. I know it is difficult to believe, but if you keep the lights off in your aquarium for two days straight, the cyano will be destroyed. Others recommend reducing the photo-period of your tank by a couple of hours. This may not treat the root...

Thanks for the reply PerfectDark!

I have a 38 gallon aquarium that has been up and running for 11 months. I purchased a bubble tip anemone (from this site) several months ago to increase my tank diversity and provide a home for my two true percula clownfish. They absolutely love the anemone, btw. The anemone appears to be...

I had the same problem and it was very easy to fix. It turned out that the silencer (the part that connects to the air intake hose) had a blocked port. I called the company and they indicated that this is a common defect. To fix it, all you need to do is jam a needle into each port to pierce...

I am betting you don't have much lighting on your tank. I too had this problem when I was entering the hobby. Ammonia and nitrite was always zero, but I would consistently have nitrates in the 15-20ppm range. Water changes made little difference. Then I replaced the 20 watt fluorescent light...
