Another way to figure the gallons is to use Google for the conversion from cu in to gal. Most people don't know that Google will do many conversions like this automatically.



My 40g sump is 16" x 16" x 36" however the fill line is at 12". To figure the actual gallons that the sump will usually have in it I'll multiple 16x12x36 which equals 6912 cubic inches. Now I open up Google and type in "6912 cu in to gal" (Actually I just put it in the search bar at the top of any browser window since I use Google for my default search engine)


Here is the Google result:

6912 (cu in) = 29.9220779 US gallons

Anyone have a link to learn Tips On Cutting and drilling Plexi glass.. Im going to buy 1/2inch PG from Home Depot, and everytime I have worked with it in the past I ended up fracturing it....

Please help...



That would be a good link. I have used a hole saw for the bulkheds and a table saw for the reat. I have never seen 1/2 in. at HD. The thin stuff they have is junk. Very brittle. Go to TAP plastic in Portland.

Don't bother with the fish. Just let the tank cycle with the live-rock for several weeks. Once there is no detectable ammonium or nitrite then you can start thinking about adding some additional livestock.


Skimmer, or no skimmer, it does not matter at this point.


If you have not read this article, you should. Scroll down to Myth 15, but the rest of it is good too.
