This is great! I’ll be following along, also having a 90 gallon, albeit five feet long. Now my only problem is that I understand electrical schematics about as well as understanding Klingon! jIyajbe' One thing I do understand is money. Could you give us an idea of what we are talking...

Just picked up a new Koralia Evolution 1400. The motor assembly is noticeably smaller while the magnetic mound now has a rubber shock-absorbing portion that adds a half inch or so. Also claim slightly more flow while using less juice. I definitely like the smaller profile. Here’s a picture of...

My wife and I were just there on Sunday and we were shocked at the amount of plastic debris on both the ocean and bay side.

Almost. You'll want to add what is recommended...I usually add more...and then adjust to equal the salinity of the tank. To do this you will need either a hydrometer or refractometer to measure the specific graviy of the salt solution. It might sound complicated, but it is actually quite easy...

Paul, you’re a sick man! ;D My guess is that it is combination of the electricity, the gases (which are oxygen on one electrode and hydrogen on the other), and the heat that does them in. A triple wammie. Happy zapping.

Part of bulb choice is not only good growth but also personal preference of the color that turns you on. My two choices would be: 1. Four ATI Blue Plus and four ATI Aquablue Specials 2. Three ATI Blue Plus, three ATI Aquablue Specials, 1 6500K (any brand), 1 Fiji Purple. I have a six-bulb...

I’m in need of advice of adding more clowns to my tank. I have a 90 gallon, five foot long tank that currently houses an interracial clown couple. I have a black clown (after Hawkeye’s discussion, I’m willing to bet this is an Ocellaris). paired with a funky orange mis-bar (another Ocellaris?)...

Hey Taz, Happy Birthday, you old man. To celebrate your birthday, I’m going to give you a guppy for each year of your birth. So how old are you...I’m guessing 80 or 90? :o I’ll have the fish ready whenever you are. ;D

Congratulations new Board. Best of luck in continuing to advance the cause. I do see one correction; Having been the outgoing Director at Large – North, that new guy you have in there also needs to be listed as NEW; a little green behind the ears, but I think he’ll fit in. ;D EDIT TO ADD: I...

Here's a chart of the difference in the hole size of a schedule 40 versus a schedule 80 bulkhead: Bulkhead size Schedule 40 Schedule 80 --------½-------------1 1/8------------1 3/8 --------¾-------------1 7/16-----------1 5/8 --------1-------------1 3/4------------1 7/8 --------1...

What were you fragging? A lot of the little buggers put out toxins. I’m just wondering if what you are suffering is a toxin effect?

I would definitely go with the 1 ½” schedule 80 bulkhead. It is for a 2 5/8 inch hole. That’s only 1/8 inch off of what was drilled. It is overkill, and I could never understand why people even considered schedule 80 for aquariums. But in your case I don’t think you have a choice. It also is 3...

The closest bulkhead is an 1 1/2 schedule 80 which needs a 2 5/8 inch hole. Agree with contacting the manufacturer. Also, where is the hole?

I think these are brand new. TBAquatics has them for sale for 39.95: http://www.njreefers.org/joomla/index.php?option=com_smf&Itemid=26&topic=23314.0

It also doesn't appear to be deep enough. When I was using a durso, the entire elbow portion was submerged.

I had another thought….if you want that industrial look and can’t get a bender….use black pipe. I think HD will cut and thread it for you. Then you only have to screw it together. If you want, paint it a pretty color. But first use a solvent to get that thin oil off the pipe. If HD won’t cut and...

Here's the word for Premium Aquatics: All of our regular bulkheads are sch 40, so the ¾ and 1” would be fine. We do have Sch 80, but they are marked 80 and expensive, the 40s are the 5 dollar ish ones.

¾ inch standard bulkhead needs an 1 ½ hole  (if schedule 80, 1 5/8 hole) 1 inch standard bulkhead needs 1 ¾ (if schedule 80, 1 7/8 hole) By appearance they look like standard bulkheads at Premium Aquatics.  I'll ask PA and double check that they are "standard" bulkheads. EDIT TO ADD...

Lights of America (Sam’s Club), now has come out with a “Cree style” spotlight. Eleven watts with 9 LEDs for about $20. Packaging says 4100K, efficacy / lumens per watt of 47, CRI (Color Rendering Index) of 74. I put this over my freshwater tank. Not sure about the 4700K?? Might cause for algae...

OK, so we are back to metal conduit. Is the bender one of the tools Home Depot rents? I actually have one, ten foot length of, I think, ¾ metal conduit that you can have to practice on. It has a slight bend-out to go around a ½ copper water line. Otherwise, it is a straight piece of conduit...
