im sure the airborne mercury you inhale adds to the delusions that you are Luke Skywalker :roll: on a more pertinent note: the epa has a webpage for locating permanent disposal centers http://www.epa.gov/bulbrecycling/ im sure there are a number of temporary locations that open up for...

Yes, I know that you are NOT supposed to just throw away PC bulbs because they have mercury in them... Does anyone know where I can recycle them? I live in the Chicago Suburbs, if anyone knows of a local place. thanks, ~mike

buy PVC couplings, and use them underneath the rocks. that way, you can keep as much of the rock above the sand, and not get mad that your $x.xx per pound rock is sitting buried beneath sand. i used several of them across the bottom of my tank... no rock collapses. ~mike

the "tilted glass" technique wont work for a mantis. they will be able to swim out. the glass will only work for crabs. i had to deal with one about the same size in my tank. here's how i got mine out. take an empty 2 liter bottle and cut the top off... just below the point where the...

Just writing to vent my frustration, and possibly warn others. i've had my 55 gal SW tank up for a little over 2 years... the whole time, i have run 2 150 watt won pro heat ii heaters. a little over 1 year after starting, both of the heaters decided to fail. slowly, the temperature display...

it would be helpful if you put your tank information into your profile. we dont know if you are trying to cover a 10 gallon or a 125 gallon tank. .22" acrylic is not really designed to span large horizontal distances. it will bow under its own weight. a better material would be thicker. ~mike

there are a few threads on the ReefCentral Breeding Forum that you might want to read. the really good ones that i have read through are by a member named "mwp". his posts usually have the words "breeding log" in the title. yeah, i know i'm suggesting RC, but they have a TON of real life...

well. you could go with concrete over foam, and make it so that you can put it in the tank later. if you make it out of several pieces, you could easily put it in the tank after the fact. the only real issue would be securing it to the wall. and you could probably handle that by lowering the...

check out ebay auction #270087950106 i believe this is the seller that the OP is referencing. he has almost all positive feedback. everyone seems to like the rock they receive. if i were you, i would spend the extra money on the fastest shpping method. get it to you as soon as possible to...

I believe the word is "modicum"... meaning moderate amount. can i answer ALL of the questions posted by "MyCatsDrool"? no, but i can answer a significant number of them, at least as they apply to my FOWLR tank. personally, im kind of curious of how old buc09 is. reading through this...

on the coralife pc fixtures (well at least the 4x65 lunar aqualight that i own) the 10K bulbs are on the circuit that controls the cooling fans. the 10K bulbs put out more heat, so when they are on, the fan is also on. if ONLY the actinics are swtiched on, the fans do not turn on. if you...

Use gloves if you are worried about hand contamination.... Heavy Duty Gloves Lightweight Disposable Gloves ~mike

the volume you stated is correct at 5026 gallons, but that is if the tank is completely full. you will have some unused volume at the top. if you leave 6 inches of dead space at the top, you will have 4712 gallons. the water it self will weigh 37,700 pounds (assuming 8 lbs per gallon). then...

what i say here is a bit misleading. the live load that homes are built to handle is a distributed load over the entire surface area of the floor. residential homes are *typically* built to withstand a minimum of 40 pounds per square foot. the fact that the 4000 lb load is applied over 24 sq...

is it this one?: http://www.current-usa.com/outerorbit.htm i would ensure you have adequate cooling airflow around that fixture. at 280 watts (in that small of a canopy) it is going to be pumping out heat. leaving the back open should be good. if you are concerned about light leaking out...

i agree with you on this one. i would be extremely hesitant to put that much weight onto a raised floor. even on a slab, that is a large load, and the concrete must be thick enough to handle it. however.... that said, 4000 pounds seems like an obscene "live load" for a residential design...

if you can modify your canopy, i would place both fans on same side, both blowing outward. on the opposite side, you should have two openings. this should allow you to move more air through the canopy, and result in more cooling. by increasing the flow path area (in this case, doubling the...

you will lose a lot of water in the winter... the air is too dry in your home. dry air, static electricity shocks, dry skin, etc.... they come with the season. to slow down the tank evaporation, you could add a humidifier to the room, but you will have to fill the humdiifer with water. so...

FYI, plywood tank stands scare me. http://phoenix.craigslist.org/fur/258156097.html ~mike

alright... standard disclaimers apply. i'm not responsible if you _____ (fill in the blank with whatever catashtrophe comes to mind). i would highly recommend that you put together a design, and have it reviewed by a competent structural engineer or architect. that out of the way, from an...

um... did i miss something? that DI resin in the original link is from AIR/WATER/ICE. I would buy it. I would also take the advice on the TDS meter. they will give you a more qualitative measure of the quality of your water, rather than eye-balling the color of the filter and DI resin...

sorry, you did goof up the math :P the equation you used for the volume of a sphere is incorrect. here ya go: volume of a sphere = 4/3*pi*r^3 for a 30 inch sphere: volume = 4/3 * pi * 15^3 volume = 14137.17 in^3 1 gallon = 231 in^3 so, 14137.17 / 231 = 61 gallons. however, you will...

get a second tube of silicone. when sealing a tank, you DONT want to run out and have to leave to get more silicone. if you dont need it, you can return it. ~mike
