I picked up a floating hydrometer and I'm wodering if they are affected by barometric pressure? When I float it in RO water it reads 1.004. Since I'm located in Iowa, which is above sea level a bit, will this affect the reading a bit? As it is, I use 1.004 as a base reading and adjust...

I have a serious problem in my 55g reef. This tank is about 5 years old, and is well established. I've kept reefs for about 15 years, so thought I'd seen everything, but this has me beaten. The symptoms are that everything is covered in brown algae, which is more dense nearer the light (10K MH...

Getting back in the hobby after several years out and am currently planning a reef in my new house. We really did not plan the house with a reef in mind so we have some obstacles. One, the sump will have to be quite always away from the tank (1st Floor tank and Sump in the basement). Is it...

I know the reef community preaches RO/DI. I'm wondering if anyone on this forum has had any personal experience with the Kold-sterile filtration system. I just don't like having my water being wasted making RO/DI. I only find some old articles/forums about this product. Sounds like they were...

I have a beautiful piece of pulsing xenia that grows vigorously. Every month of so I cut it back to try and control it. Sometime little pieces of it fly loose and set hold on my live rock in places where I do not want it to grow. I was wondering if any one had suggestions as to how to control...

I'm thinking of buying a Tunze 6060. Anyone out there have one? How much noise do they make? George Patterson All successes in conservation are temporary. All defeats are permanent.

Does anyone here use mangroves in their sump or tank? Cindy

I'm about to move my 40 gal reef (Fri) to set it on a new stand. As long as I'll have almost everything removed, I wonder if anyone has any good guidelines on aquascaping. I know that all should "firm" so things don't tumble (like they do now). I want to maximize the number of corals I can...

Now that I have loads of pods in my cycling tank, I`d like to keep the population going. What do they eat? I guess once I get predatory fish in there, I`m gonna see a lot less pods. Is there something I can do now within the tank itself--(IE: NOT separate tanks,refugiums etc)) that will help ensure...

Interesting...just found this today Welcome to MJmods.com your parts warehouse for modifying your maxi jet into a high flow pump. http://www.mjmods.com/ http://www.reefvideos.com/

I've been using the Hagen test kit from the start and was sure that my Cal levels were properly read. Then I ran out of KH solutions and not being able to buy refills for this parameter, switched to Salifert. Well, using Hagen I was getting low Cal levels and low KH. Used buffers to bring KH...

Can aiptasia anemones stink adjacent coral?

What does it mean if the Skimmer is not producing foam? (Its not broken,sometimes it does,sometmes it doesnt.) Does it mean that at that particular moment there is very little free-floating dead organic matter in the tank? Is this a sign of improving water quality? another from the "newb".....

Hi, Found this guy washed up on the beach after a big storm: http://www.dietandtraining.com/Parts/DSCF0050.JPG About 1.5" long, has tiny pinchers in the front, have 35mm film that shows more detail, but figured I would give it a shot with this one digital I had.

The water has been in for abot 3 weeks. The Live Rock and Arag-alive sand have been in the tank for 10 days. The ammonia has been steady at .25 for 3 days The Nitrite at .2 for 3 days. There are Hundreds of Pods scooting around. About a dozen teeny-tiny snails on the glass. About a half dozen M+M...

Some recent pics of my 3 year old 66gal mixed...

As my tank is cycling, I`m pondering the the thought of a kind of Faux-Reef set-up. Not the plastic stuff!! Im thinking of having inverts that are not that expensive or are relatively easy to keep. (IE NOT Corals or anenomes!) For instance: Feather Dusters----are there different varieties of...

What is that purple stuff on live rocks? TIA

Hey guys, I have a new 125-gallon glass tank with a built-in overflow. The problem is that, even though the tank is level, the water level stays below the plastic rim of the tank. Is there anything short of modifying the built-in overflow that I can do to increase the water level in the...
