PC pin corrosion   1/4/06
How are you guys? <Great>
I have quick question about pin configuration on the Coralife power compact fixture. Is there any type of substance that you can put on the pins of a bulb when you change them to prevent the pins from corroding(?) inside the end caps? <I spray a small amount of WD40 on mine and wipe off excess.  James (Salty Dog)> <<Mmm, this is a local co... the product is diesel fuel, kerosene and a perfuming agent... I would NOT spray this around aquariums. RMF>>
Thanks,

Could you please tell me what the end part of a ballast is called? <They are called end caps/sockets.>
I bought new Coralife bulbs, and when I was taking off the old bulbs, the end part broke!! The part that the pins go into. What a drag! They were so fused on to the bulbs, it was ridiculous! <Should coat the pins of the lamps with a silicone lubricant to prevent this.>
I bought Coralife 65 watt 21 inch straight pin compact bulbs. Now, my tank is in the dark thanks to this ridiculous design!!
So, now that I've vented a bit, can you tell me what the heck they are called so I can order some? I had to cut the wires that lead from the ballasts also, because they were frayed. Do you think it is safe for me to re-wire onto these caps?? <I've never saw PC end caps for sale in any of the on-line stores.  I'd contact the manufacturer for their advice. <James (Salty Dog)>
Thank you! <You're welcome>

Issues with Lighting Fixture, fluo.    9/11/07 
<hello>
I had a hard time finding the information I am looking for. I apologize if this question is similar in content to others you have answered. I have a 55 gallon reef tank that has been up and running successfully for two years. All parameters are normal. Fish and corals thriving. I have a current satellite fixture that has been an excellent choice. However within the past six months the lamps (bulbs) on one of the ballasts began to flicker. At first the flickering was temporary, then it became constant. I bought new lamps and this did not solve the problem. Then my boyfriend (an electrician) disassembled and reassembled the unit. It did not flicker again for about two weeks. Now it flickers randomly once or twice a week, maybe more and I am not there to notice. Several opinions have me confused. One source told me that it was probably a loose wire, not to worry. Another told me that a new ballast was needed. Before I spend the money on a new ballast, is the, now, temporary flickering, harmful and or indicative of a larger issue? If it is, or was, a loose wire would a new ballast be of any benefit? I tend to be a hypochondriac but it seems that my Anemone may be "reaching" for light more than is usual. Could the lamps be producing less light, without giving any visual indication? Is there any way to measure the light that the tank is receiving? Any input would be most appreciated. Thank-you.
<The best action is to replace the ballast. While you are at it see if there are fans on the end of the fixture. If there are make sure they are working. If there isn't check into purchasing some and installing them. The fans will keep the fixture cooler and make the ballast and bulbs last longer.>
