I'm afraid this post doesn't include any references to scroll sawing or pyrography, but if you are interested in what comes out of your tap please read on.
Those who have been following this blog will know that I have been very busy renovating the bungalow we moved into almost two years ago. Well, the work is almost done so I thought I'd treat myself to a new tropical fish tank. I had successfully kept tropical fish in the eighties and nineties but divorce, redundancy, heart attack and several house moves saw me giving up the fish.
Anyway, now that my days are more settled I thought I'd rekindle the hobby and spend the rest of my days sitting on my couch watching the fish meander up and down the tank. What could be more relaxing?
I went out and purchased an 87 litre tank and all the stuff that is necessary to set up a new aquarium. I filled it with water and and left it for a week to start the cycling process prior to introducing some fish. So far everything was going well, then I tested the water to see what the hardness and ph levels etc were.
Everything was okay except for the water's general hardness figure. The test strip indicated that the water was very hard and I should proceed with caution.
I scoured the internet for information on tropical fish and hard water and even bought two books on the subject. Advice about which fish could be kept in hard water and what could be done to reduce the hardness was easy to come by along with some conflict.
The majority suggested the only foolproof way to reduce hardness is to go to your fish dealer and buy RO water, (known as RO water because it has been through a process of reverse osmosis) and put that in your tank instead of tap water. You can than add some minerals to it to make the water safe for the fish.
However, the minority suggested that because most fish were now bread in captivity, water hardness wasn't a big issue any more and that fish had now adapted to it. I mentioned before that I'd kept fish successfully when I lived about 8 miles away, I hadn't tested the water then so perhaps the minority were right.
Anyway, I decided to give it a go and purchased 4 Zebra Danios which are renowned for being hardy and able to tolerate hard water. One died the very next day but because the other three looked okay I put the death down to the stress of transportation. However, two days later another one died which was upsetting. Was it the water and just how hard could it be? I decided to buy a more scientific test kit which would produce a reliable figure. Once this was known I could decide what to do next.
The test involved putting some of my aquarium water in a test tube and then counting how many drops of a special solution it took to make the water change colour.
The leaflet that came with the test kit advised that some tropical fish species like Tetras need to have water that changed colour when between 3 and 6 drops were introduced. Other tropical fish, like guppies etc could manage to live in water that changed colour when up to 11drops were needed.
The test scale finished at 12 drops, which according to the leaflet was only suitable for keeping gold fish. Armed with this information I began counting the drops as I began the test. I was a bit concerned when I reached 13 drops and the water was still the same colour and by the time I'd reach 20 I was under no doubt as to why the 2 Zebra Danios had died. It took more drops to change the water in the test tube and I was devastated when the count went to 25. What the hell is coming out of my tap liquid rock?
My next step was to see if there was any information on my water companies website and I was pleased to say that there was. However, I wasn't quite so pleased when I found what I was looking for. According to them the water for my post code is very hard and the figure suggested that it was slightly harder than the the result that I got from my test kit.
Now you might think this is unacceptable and there must be a mistake. Well there is no mistake and what's more there isn't even a standard so they they don't have to bother complying.
Sadly, this was the end of another dream. Buying reverse osmosis water and humping it about the countryside isn't an option. I purchased the fish tank hoping for some relaxation, so doing a 20 mile round trip for a tank full of water every week is not on. So, I returned the 2 surviving fish to the fish supplier and put the tank up for sale on ebay. It cost me about £400 in total and I guess I'll be lucky if I get £75 for it. The only good news is that I won't be killing anymore fish.
At this point I asked myself a serious question. If fish can't survive in this water, how can it be safe to drink? In my opinion it can't so I went out and purchased a water filter. It won't get rid of all the nasty stuff in the tap water like florid, but it it will help with some of the other stuff.
By the way the art challenge is going well and you can get an update here if you would like to see my latest effort.
