We also discovered that Ikea often have 'useful' items in a cage in the carpark, thus we once acquired several large sections of table top which I think loitered in the garage until we moved and then made their way to the tip But they might have come in handy ...
Great, thanks for that, will have a look in the DIY stores and see what I can find I've seen a few people using pipes but sometimes in the DIY stores they smell a bit 'plasticy' which was a bit off-putting;it's good to know what to check for
Just wondering if anyone else has used drainpipe in their tanks for fish to hide in? Ivor the CAE did have a little ceramic right-angled pipe ornament that he liked to hide in, but he's got too big to fit in it now without having to bend himself round the angle! He also likes to be able to turn round and come out the way he went in, which he now can't do, so he's stopped using it. He still has his lurking spot under some slate, but it's not quite the same
I had a look online for larger pipe ornaments, but they don't look very large to me. So was wondering about using drainpipe, but not sure if the plastic would leach anything into the water?
It should heal up fine, they sort of zip up again You'll need to make sure that the water is ok for ammonia, nitrite and nitrate and keep an eye out for the edges of the split looking a bit discoloured as that might indicate infection setting in. But generally speaking if the water is clean and they've got a good diet then any little nicks and tears caused by general clumsiness on their part should heal up no trouble
Personally I don't really like reductions of more than a couple of degrees at any one time as fancies can be delicate little souls and consistency seems to work better for them. If you're interested in calculating the drop in water temperature I did find a formula ages ago, adjust the figures for your own situation:
255 is the amount of water left in the tank after water has been taken out for water change (litres/kilograms). 4186 is the specific heat capacity of water (don't ask me what that is!), 22 is degrees (temp of water in tank), 85 is amount of water being added (litres/kilograms) and 6 is degrees (temp of water being added). 18 is the overall temp of the water once the two volumes at different temps have been mixed together. This means there is a 4 degree drop in overall temp if I add water from the tap at the temp it is currently coming out of the tap at. Obviously this doesn't account for the heater in the tank kicking in when the tank temp drops as I add each bucket of 6 degree water but it gives a rough idea.
Re: Using battery powered gravel cleaner on sand
I think that's my 'brilliant ideas' quota gone for the year now I do sometimes waft the net around my tanks, the fish don't realise it's a net as they've not faced one for years so they often swim into it while I'm wafting!
If you train them to use a loo they'll just spend hours in there with a newspaper and then you'll have a lot of papier mache to contend with!
