Hello!
Either you have not registered on this site yet, or you are registered but have not logged in. In either case, you will not be able to use the full functionality of this site until you have registered, and then logged in after your registration has been approved.
Registration is FREE, so please register so you can participate instead of remaining a lurker....
Please note that the information requested during registration will be used to determine your legitimacy as a participant of this site. As such, any information you provide that is determined to be false, inaccurate, misleading, or highly suspicious will result in your registration being rejected. This is designed to try to discourage as much as possible those spammers and scammers that tend to plague sites of this nature, to the detriment of all the legitimate members trying to enjoy the features this site provides for them.
Of particular importance is the REQUIREMENT that you provide your REAL full name upon registering. Sorry, but this is not like other sites where anonymity is more the rule.
Also your TRUE location is important. If the location you enter in your profile field does not match the location of your registration IP address, then your registration will be rejected. As such, I strongly urge registrants to avoid using a VPN service to register, as they are often used by spammers and scammers, and as such will be blocked when discovered when auditing new registrations.
Sorry about all these hoops to jump through, but I am quite serious about blocking spammers and scammers at the gate on this site and am doing the very best that I can to that effect. Trust me, I would rather be doing more interesting things with my time, and wouldn't be making this effort if I didn't think it was worthwhile.

A light question
I'm startimg the setup of a used 65 gallon aqaurium that came with a 192W CF. I am a beginner in the worst way, but I know that I need more light for a reef aquarium. I cannot afford a MH right now but am considering an additional 100 to 150W CF. Will this be sufficent lighting for a reef aqaurium with live rock, hard and soft coral, and fish? Also, has anyone out there used the Florex 65W bulbs that claim to put out as much as a 500W CF and 4500 lumens?
Help, please!

You're at almost 3 watts per gallon so if you poisition the hard corals up high, softies in the middle, and shrooms at the bottom, you should not have any problems. Just remeber most acropora will lose their color unless they are under MH so if you want hard corals stick to the eaiser types. Also stay away from any of the clams. They need a LOT more light.
BTW, what is the rating on the bulbs? You can have 1,000 watts running over the tanks and it will do nothing if it is the wrong spectrum.
I prefer a more deepwater look so I tend to use higher kelvin bulbs (they also penetrate deeper than lower K ones).
A good mix would be 10K supplemented with true actinic (I know, almost impossible to find in PC's). You may also want to consider using just 20K bulbs.
I don't buy the hype regarding lower watt bulbs giving out the same as PC or MH. They are nothing more than glorified fluorescent tubes. Tritons were advertised basically the same way for years and they may have a slightly better output but nothing compared to the claims they were making. You could not grow acropora (colorfully and be able to frag it) under these lights like they claimed.

Thanks so much for the info...
I've decided to get another CF. It will have a 12K and an atinic. The bulbs in my current CF are a 10K and an atinic. I will have a total of 322W. When the money is a bit better, I'm going for the MH with the flourescents and atinics. I will definitley follow your advice about the placement of my corals and mushrooms. It sure helps to talk to those in the KNOW!
Thanks again!!!
