The moral is that old people are a bunch of liars.

Hmmm, Just did a little research to find some average flows across reefs, not much luck but I did find one guy claiming he'd measured it at about 15cm/second. So...That movement through a 1000X500X600 tank would be...Ummm...540X turnover per hour.

People with freshwater tanks are way too used to tanks replicating stagnant ponds rather than an environment with currents. 50X turnover is a good target.

Cold water as in room temperature inside a house or cold water as in a pond outside in near freezing weather over winter?

Contaminate your tank with what? A growing plant?

Not even close.

I've had 4 total of them. They're not the exception. They're just not as bad as most. They will, still, quite happily bite out small fishes throats, bite off their tails, etc. What do you mean you won't find them in NZ anymore?

First, you'll need to narrow it down, what species are you talking about? Is it actually freshwater? Is it brackish? Is it freshwater when young and brackish when older? I believe brazillian puffers are the only true freshwater ones available in NZ, but there are a lot of brackish puffers sold as freshwater. Short story: No. Long story: Maybe a little but no.

I put mine at least halfway down. That way they don't become exposed when I do water changes. It's just annoying having to remember to unplug them and then plug them in. I had a tank that the cord didn't reach far enough for that. So many times I'd have it draining out the door and check the tank to find it full of steam and the heater sizzling away. Or the other extreme I've left the heater unplugged for a week or two and only noticed it when I stuck my hand in the tank and it was about 17°C.

I'm pretty sure there's nothing you can do to kill the light unless you drop it.

*Bangs on tank next to the computer* Put your fin up so I can compare. *Bangs harder* Put your dorsal fin up, dumbass! *Bangs more* Fine, just wiggle your tail and glare at me with your fin down, it's nowhere near as big anyway.

Depends how you want to look at it. Could argue that no pump can pull water. They push water creating a void which ambient pressure pushes more water in to fill.

I've been meaning to do this for a while since everyone seems to argue that canister filters will flow more if you have them higher. These are tested with an empty old CF1200, measurements were made by running the filter into a bucket with the outlet hose at approximately tank water height. On floor: 2.5L in 15 seconds, 600LPH 1300mm from bottom of canister to tank water surface Middle: 2.5l in 15 seconds, 600LPH 600mm from bottom of canister to tank water surface Top: 2.4L in 15ish seconds, 576 LPH +80mm(Above) from bottom of canister to tank water surface Raising the filter 700mm made no difference at all in the flow. Putting the filter above started the filter sucking a little bit of air in and when I started the test it took a second to clear the air out and start flowing well. That's probably what lead to the lower flow at that height. A newer, more well sealed filter likely wouldn't have this issue. Also it would be a pain in the ass to prime the filter, so I wouldn't suggest having it above the tank.

Waste not, want not.

What if you had some guppies tattooed on the side of one of the parrots? Could you then sell it under the scientific name "Cichlidae Yodawgii?"

He should be fine....Let's see...He'd need 2 fingers remaining so he'd have to screw it up 8 times in a row before that becomes a problem.

........So? :thup:

Just get a couple of these. It won't go ANYWHERE.

Leave them to it. That's what they always do.

It's been 7 minutes. You're late.

If all else fails... I'm sure you can fit a tent and enough supplies in the trailer...

If the fuzzy blobs I'm looking at are the fuzzy blobs you're asking about... :slfg: They look more like cuttlefish than squid.

They work fine above the tank. Just makes it tough when the filter is empty to siphon out of the tank and fill it.

Looks good, now you need to work on your rockwork. I've been tempted with mine to add a bunch of fake corals and that resin sunken HE162 figurine that I've seen a few times.
