They've got the croc (or is he an alligator?) at The National Aquarium. There used to be one at Brighton in ChCh too.

I believe the PVC is thicker and copes better with exposure to sunlight. The polythene tends to break down over time. The proper liners seem to vary a lot in price. If the pond is relatively small, which yours is, I doubt you need the high end thickest stuff. Bear in mind it also is very heavy so dragging a large piece into position isn't easy! If you aren't on a tight budget and want to do the job right I would go for the pond liner. I think with the liner you will have less need for an underlay as the liner itself will absorb the lumps and bumps.

It seems to be a case of you get what you pay for. The proper pond liners are thick and expensive but they often have 10 - 25yr guarantees. A lot of people recommend the liners farmers use on their dams as it is a lot cheaper than the pond liner. It is thinner too and I don't know about guarantees. I think this differs from the stuff they use to cover silage. As for underlays, this depends on your ground and how rough it is. Many use old carpet or sand. The use of some sort of underlay would definitely make the lining last longer.

Not in the wild caper

If your fish are happy I would leave the pH as it is.

I know nothing about frogs or their requirements but I don't think you need any type of mechanical water movement thingy :-? Hopefully someone else will tell us if we are wrong 8)

For all you need to know (I hope) go here

No it doesn't need a pump

Jude suggested "I thought there was supposed to be a worm at the bottom of a tequila?"

I think we have a winner!

"Who drank all my vodka?"

I believe she doesn't have phone or Net access at the moment.

I think I bought mine off Trademe. Not actually got around to using it yet :roll: Hmmm I wonder where it is? :-? :lol:

Glass would be good and trap warmth. Plastic, depending on thickness, will develop a sag in the middle.

Can you feel me twisting your arm Stella? I thought her coming to conference was a definite! I was looking forward to meeting her.

After checking into it, we will have to back out as I can't get time off work Perhaps next trip

Cover the bath with something

You can adjust the flow on an airstone to have it bubbling as fast or slow as you like. It should not upset the fish.

The airstone would be more just surface and unless it was really forcing oput the bubbles I doubt it would upset any fish.

It is crowded compared to lately when it has just been me and Jude. Used to be 15+ in there most nights in the past.

Bananas

So this is why we got crowded about 7.40pm? :lol: Bring your own chairs next time :lol:

An airstone will increase water flow in a limited way. Filters create more flow as they are more powerful and as they our the water back into the tank it creates a flow. Some filters have their return pipes under the water surface so the flow isn't seen so much on the surface. If the filter returns water at, or above the water surface, it creates more flow. Airstones create flow as the bubbles break the surface but to a much more limited degree. I think you are getting flow mixed up with increasing oxygen content. If you have a filter, or airstone, creating waves on the surface, you are increasing the water surface area and the amount of oxygen exchange.

I thought it bad enough that children were given their own mobiles but these guys???? :lol:

When I had minnows they certainly lasted a lot longer than 2 years.
