I figured out what the Skimmer is... It's a Sea Clone 150. =\ I think I
remember reading that they suck.?.


That's the general opinion. There are some mods that supposedly make
them work better.

Supposedly, all you need to run it is a power head. I'm still looking in to
that but being that I wont need it until after the tank has cycled, I'm
kinda puttin that on the back burner. Do you think that will be sufficient
for a FO tank?


Impossible to tell. It depends upon your bioload, and the size of the
tank. The only tanks that I know that are skimmerless are very lightly
loaded reef tanks. This would be maybe a couple of small fish in a 100
gallon. I'm not aure how far a seaclone is above skimmerless.

Also, if you are using live rock as part of your cycle, you should be
running the skimmer now.

I decided to get a RO/DI unit. I found someone locally who claims these are
very high quality. As soon as I get some specs I will share them but in the
mean time, If I am using an RO/DI unit, I do NOT need any conditioners
right?


Right. A good RO/DI will take out pretty much everything, including
chlorine, leaving you with just regular H20.

If you are shopping, be sure and check the rate. Most home units are
about 5 gpd. That's gallons per *day*. You don't want anything that
slow for an aquarium.

One more thing and this may seem really stupid but... In regards to weight.
Everyone knows that sal****er is more dense than fresh water. Regular water
weighs approx 8.33 lbs per gallon.

Am I correct in assuming that the specific gravity from the hygrometer can
be used as a multiplyer to calculate weight per gallon? For example if my
reading is 1.020, can I multiply that by the weight of water to figure out
how much the salt water will weigh? 8.33 X 1.020 = 8.50 so it would only
weigh 8-1/2 pounds instead of 8-1/3?


I can't imagine why you would need that accurate of an estimate. Just
use 10 lbs. :-)
