Are there any dangers to overfiltering a tank? I plan on setting up a ten gallon saltwater tank with a five gallon refugium (largely for water stability) and would like to filter it with a Penguin 170. I have a Penguin 330 for another tank and I could use the same cartridges, plus I could swap...

Whew!! I ran to radio shack today and picked up a 100k Potentiometer. Better than than the 1M but I may try the 50k just for giggles.

I don't think I was clear enough on my black/yellow wire problem. Flat telephone wires have a smooth edge and and edge with a crease down the middle. What I did was attach the rj11 with the crease side down. Depending on which random end of the telephone wire I grabbed when I attached the...

I got a little impatient and picked up a similar Potentiometer from radio shack. At maximum it doesn't dim the lights (compared to when it's removed) but you can only turn the knob about a 1/8" before the lights completly dim out. Not enough control.

I set up some moonlights using thelebos modular design and when I add the Pot (I inserted it on it's own phone line between the power supply and the first line expander) the light output is drastically reduced. I'd guess that the maximum output is 60-80% of non-Pot output. I bought all the...

I've got a better question. Thelebos.com manual uses 1/4 watt resistors. I was going to use different LEDs and the only appropriate 47 ohm resistors radioshack has are 1/2 watt. Does that matter?

What's a good rule of thumb for how many led's you can add without it being too bright?

Hi, I'm new to these boards and I have a quick question. I have a friend who's helping me construct a canopy. It's going to be a simple box, ten inches high, that sits on top of the aquarium with a flip up front and an open area six feet by 4 1/2 in the back just above the tank. My aquarium...
