Sure, if it's used as a coolant it will cool the object quicker. But that's about as relevant as how many times you can skip a rock on water in this case. More important in this case would be the specific heat, which is basically a measure of how much energy it takes to increase the temperature of the medium a given amount. Water is FAR higher than air. Obviously it's going to take more energy to heat(Or cool) 100KG of water in a 100L tank vs approx 100 grams of air. (Obviously, thermal conductivity matters too but it's not enough to change the results much)

That's kinda cool.

I do, I'd forgotten one of my sumps. It's about 16,000 liters.

Oh, I forgot a bit, make my total 18,640 liters.

There wasn't a single thing in there that wasn't fully applicable to scuba. The moderaters are just pervs.

Given it was 20 minutes between my first and last topic reply notification for it...

How long the thread about the scuba diving club in Ireland would last.

It needs to be primed. They don't pump air very well and the impeller chamber is full of air. Easiest thing to do is unplug it, pull the outlet hose off where it goes into the tank and siphon some water into a bucket. That should clear the air out.

That's because you're killing all the bacteria in the filter every night so it's built up more elsewhere. That way you don't lose any. Essentially you're making it just a mechanical filter.

About 640L here.

If it's only enough that you can feel it in the cut(Shorter path for the electricity to your nerves) I wouldn't worry about it. It's normal.

Then I'd say they're tropical. They'd have been long dead by now if not.

If they're still alive in a couple months that will answer your question.

Would you please come remove the rats in my ceiling? Oh, and the spiders please. Since it's such a horrible crime to kill them, it's your responsibility come get them and save them from death...

Since you don't want to check a fish shop, buy the ones with the hooks, remove the hooks and replace with cable ties or string.

I've never noticed any tannins from beach driftwood. And the amount of salt you'll end up with, especially after a quick hosing off of any sand, is so little you'll only need to worry about it if you're the type of person that doesn't blow into the bag when transporting fish out of fear that the CO2 in your breath will change the PH too much and kill the fish.

Yeah, putting the noodles in a bag is helpful. Otherwise just dump it all into a bucket of tank water, swish it around, scoop the noodles out and put them back.

Only the little fluffies that are allowed to roam are vermin.

Probably wouldn't be hard to get them into NZ. Just import them as Alaskan Malamutes. I know there have been several people that have imported wolves from Alaska into Hawaii where they're banned and despite DNA testing Hawaii couldn't say they were wolves.

There are a lot of tunnelwebs that are pretty damn close to tarantulas, not quite as big but when they're running towards you from the woodpile they're close enough...

Hehehe, Yeah, where else are you going to get 60+gigs/month for $50?

Isn't the reason obvious?

Cuttlefish.

That's known as trusting the slimy salesperson, that is not very bright.

If you're stupid enough to not look at how much it costs then you deserve the charges. It's not as if they hide them or it's something in the fine print.
