If you we're closer i'd be interested in the CO2 extinguishers.
i got a few out of date ones in the work shop
i tried one from the 60's it still went off and worked!I have a lot in my van.
99% of the units I removed never get used.
So may that carry on.
Old CO2 fire extinguishers are often in demand by some tropical/marine fish keepers.
As a genuine seeker of knowledge, why?
Co2 bubbled through the water is great for planted tanks, when all balanced you can see the plants pearling oxygen in return.
Never knew that.
However, in a previous incarnation I kept tropical fish, but the tanks had a 2”thick layer of riddled garden soil in the bottom into which the plants were planted. Did it work? By God it was stunning! The plants thrived in the soil to the point where you could almost watch them growing. They also took all the nasties out of the water to the point where I stopped testing it. Not a trace of ammonia, nor nitrites and nitrates, nothing.
The plants took it all up, and it was a revelation, but when you think about the natural world, there aren’t many lakes that have water pumps and filters fitted, and they don’t have partial water changes either. And I’ve dived in lakes that have left me open-mouthed at the amount of life in them, so good old Mother Nature must know something we don’t.
about £10 a go
That's a lot of dosh.
Next time I am down that way and I haver some to loose I will only ask for £5
Mate of mine used to disappear into the loch at Arrochar when the rest of us were in the pub, and just sit on the bottom looking at stuff.And I’ve dived in lakes that have left me open-mouthed at the amount of life in them,
