weir (click to hear the word) (wîr) n. A fence or wattle placed in a stream to catch or retain fish. A dam placed across a river or canal to raise or divert the water, as for a millrace, or to regulate or measure the flow.

Thanks! Great link!

umm...what's a 'weir' ? :D

That's what I originally thought, but that doesn't seem right. That would mean for a single 2" overflow, pushing 2350 gph, you would need a linear overflow of 35". If you figure the spaces between the teeth are typically 0.25", then you would need 140 of these spaces. Figure a 0.5" 'tooth' in...

Handyman- I did some research...there is a drain pipe size calculator on reefcentral which also provides "minimum linear overflow size"....not sure what exactly that means...BUT a single 2" bulkhead can handle almost 2500gph... Any idea what they mean by that linear overflow size?

I've got a 180g with two 2" bulkhead drilled about 3" from each other on the back glass. I'd like to build a simple internal overflow box to over these bulkheads. From a flow-rate standpoint. I plan to use an AM3000 which should end up returning water at a rate of roughly 2000 gph, and I'll...

Thanks for the replies. Part of my concern though, is that there is an overhead sophet (sp.?) which partially projects over part of the open tank. Although it's not likely, it is possible that condensation could accumulate here, then drip into the tank. What if I went with something like KILZ...

The contractors are literally, at this moment painting the finished basement, and want to know it there are concerns regarding what type of paint can or cannot be used in the small area where the tank will be. The concern is that some 'Hi moisture area' type paints contain Mildewcides which...

Great points. Thanks everyone for the replies! I'm going to stick with the Lifereef.

I'm upgrading from a 125 to a 180 gal, to house primarily SPS corals (and prolly a few clams). I plan to keep a light to moderate fish load. Currently I have a Lifereef HSV-24 in -sump skimmer. Will that be sufficient for the 180 or do I need more? (if I need more, can I add another skimmer...

Actually I have one Purple Tang, and he won't touch the stuff. I have a 125 gallon tank with a 30 gal fuge and a 25 gal sump. I have spaghetti algae (Chaetomorpha) in fuge, along with some Ulva and Gracilaria, and I've got the Caulerpa scourge in the main tank. Sharkky- "Can I refill your...

This is kinda a two part question: A) If you've taken on Caulerpa racemosa in your display tank and conquered it, please I want to hear from you.....How did you do it? and B) How do you prevent Caulerpa from entering your system on LR? I've ordered LR which appeared completely 'naked' and...

Wow! Quick and helpful responses! Thanks to everyone who took a moment to do this. I'd like to add some additional information: 1- All the electical devices (except the Metal Halides) are on GFCI receptacles. In most cases, a power strip is plugged into the GFCI which then feeds 3 or 4...

Okay, I've just spent the last two hours checking my tank with a multitester meter, and reading the threads on stray current in the tank. Yesterday I felt a tingling when I put my hand into the tank...didn't like it very much. Today I purchased a multitester and tried to isolate where the...

Excellent! I'm going to give that a try when I'm ready to get another Maroon clown.
