we're picking up the new 250 next week, so i thought i'd go ahead and get started on my game plan.

the tank is going to be planted (probably sparsely at first until i can afford to add more)
the future inhabitants are described in my sig.

but here's the thing.
I wanted a big fallen log in the tank (hence the thread title)And, while actual logs out of the Tar River in NC are quite cheap, they're also on the back end of countless pig farms and there are signs up along the river that say "do not eat more than one serving of fish from the tar river in a given month"
so that made me feel like i shouldn't expose my babies to that. besides, i couldn't find anything big enough.

so i decided to make my own.
I went out and bought a big piece of styrofoam (2 inches by 4ft by 8ft) from the hardware store (cost $22)
and a tube of silicone.

then i started cutting.
about 2 months ago i got "the wonder cutter" styrofoam cutting hot wire. works great, keeps the mess to a minimum and makes nice smooth lines... but it takes ALL DAY LONG. each strip takes 10 minutes.
so i got impatient and switched to the butcher knife method.. which is VERY messy and uneven.. and even after the strips are cut, they still make messes. (picture included)
so then i went outside to do this, and i got an electric router thingy. (the spinny saw contraption) this worked great, but since i got 2 inch thick styrofoam, the stupid thing doesn't go all the way through.. so i end up having to use the knife anyway. I'm gonna try to find a larger blade for the router, cuz it definitely makes a smooth line and goes VERY quickly.

since the router didn't quite work, i decided to stop for the day. but i figured i'd go ahead and get the thread started and the few pictures i've already taken up.

Not putting the styrofoam into your tank I hope?...I'm fairly sure it's toxic to fish./

Must be nasty to live next to factory farms...Then again I wish factory farms would be next to nobody and no longer exist:mad2:
 
styrofoam is not toxic to fish.. tons of people make styrofoam backgrounds.
 
Cool, it will be neat to see how it turns out. What diameter are you going for? You can use PVC pipe that's heated until it's soft and pliable, then deform it however you want. It would make good branches too if your trunk is going to be too large.
 
A Circular saw also cuts this foam nicely.

get a blade with lots of teeth, and move it at a slow gentle pace, and it will make beautiful cuts in the foam.

I will say though, I did mine with a crosscut blade that had big teeth and it still cut nicely.
 
i'm thinking the log will be a little over a foot in diameter, and about 4 ft long. i'm not gonna be able to do much more work on this until sunday, so hopefully i'll have gotten a better blade and can show some progress then.

we went and saw the tank last night. its a little less square than i remember.. so i may tweak the log plans just a bit so it looks more natural.
we're hoping to pick it up in the next week or so (whenever we can get some very strong friends to help us out, lol)

cant wait to see how it turns out!
 
You can also use an electric meat carving knife to cut. But go slow.
 
I went to the hardware store and found a souldering iron with different tip attachments.. one of which was a 2inch foam cutter!!
this baby gets up over 900 degrees Fahrenheit and works GREAT.. i should have more pics up soon!
