After all those discussions about stray voltages:

go figure ???
Cool. I thought that pool NASA uses for training was the deepest one, but this one at 33m is really something. The only thing I don't like is that it is EMPTY (except the water, of course :) ) I mean, most of the people dive to see things underwater (reefs, fish, wrecks).
SW mix is behind the door. How are you going to move that water into sump? Assuming that the room is not already built and the door is already there where it is, I would swap it with the SW mix tank, and place it in the corner. But then it also depends how you gona place the feed lines to and...
There are several types of bubble algae that are common in our tanks.
Ventricaria ventricosa and Valonia macrophysa form large bubbles. Some people advocate using syringe first to puncture the bubble and suck-out the interior liquid that contains spores. I am personally a bit dubious about the...
Carlo,
I have found a great idea for you:
The rest of their designs are really bad (aquascaping and stocking) but that one is really something with such enormous potentials ;D
Rich I am with you completely on that sentiment. If somene is not capable of maintainig FW tank, no way they will be able to maintain any kind of SW tank (unless there is huge difference in motivation). Someone once posted that it is the same to maintain SW and FW tanks, but that is completely...
Just a small comment on biowheel HOB filters that is not about their filtration efficency (which I also think is great). I had products from two different companies, and both of them were creating a fine mist of splashed water. While this is hardly noticeable in FW systems, in a salt system...
Wendy,
unfortunately I would have to disagree with you on the refractometers. From my personal experience and from what I see from other discussions, they do not neccesarily seem to be that accurate. That one that you got from e-bay looks exactly like mine and mine is WAY off. Now, maybe some...
No need to disagree since both of your statements are true ;D
Dave is absolutely right when he says that water movement is dependent on what specimens of life you keep. Ken your statement that proper water movement is a must is also true, specially when combined with his statement into "proper...
If the rock is fully cured, then, there should not be significant die-off. That is what curing the rock means. If the rock is cured, DO NOT make water changes during the start of the cycle. Ammonia MUST rise. Then nitrites MUST rise after that (when ammonia should start falling down...
If the live rock is fully cured, you add it immediately so that it becomes a part of nitrogen cycle. If it is not fully curred, some people prefer to cure it first (additional 2-3 weeks before you put in the tank) and some people prefer to cure it in the tank. That way the biomass that the...
That is one of most hardiest SPS corals (what do you think, why else would it be so large ;D ) and a good beginners choice. Try to get a frag of it, and if you can't and you are willing to travel to Plainsboro, I can sell you a small frag.
Doable, but pain to maintain and really ugly with all that stuff (heaters, skimmer, etc) in the tank. Top-off real pain, water changes very disruptive, dosing of any chemicals had to be done with extra care. My previous setup started sumpless, but after a while I gave up.
Assumption is that temperatures of both specimens were roughly the same. Temperature affects salinity measurements very significantly. So, if those were the same (and even if they were not):
Before you use the hydrometer, you need to "wash" it well. That is, if you haven't rinsed it very...
