they are 30 quid a pop online , that is money as a single parent I don't have right now. Nor do I see myself pulling this kind of money out weekly just to satisfy the need of those online.
It is interesting to hear about your experience since 1959. It sounds like you have seen a lot of changes in the hobby, which makes it even more surprising that you are struggling to accept that a stable system can look different from the one you have been practicing for decades. You call my setup a hypothesis, but it is a system that has been running for eight years without a failure.
In science, a hypothesis that consistently produces the expected result over nearly a decade becomes an observation.
Hello; The liquid test kits I am familiar with were around $30 something last time I bought one years ago. Thing is the chemicals in the kit do not have to be replaced each week. The kit supplies can last for many weeks to months to years I guess depending on how often you test. There is, I think, a time frame for some of the test liquids to remain good. So, I take it the promised measured results will not happen????
Hello; what I tried to explain was when I was 12 years old and mowed enough lawns to get a tank, I did not know of WC. For many years I ran tanks with UGF (under gravel filters) and only topped off the tank for usually a year or so but sometimes longer. Everything was run on weak air pumps. I overstocked & overfed. I was running tanks early in my fish keeping under worse conditions that you describe. I slowly learned what are better ways to do things.
I currently have only three tanks set up. One maybe running as is for 12 or 13 years. The others approaching or beyond 10 years. I have evolved from keeping fish with some plants to keeping plants with a few small fish. My 55 gallons

has maybe 10 or so zebra danios total. But lots of plants.
I do not have a very recent picture but will look for a representative picture.
I do not reject your claimed outcome outright because a scientific approach ought not to become bogged down in it's own dogma. Too many times, a new approach has proven true. Thing is your claims fly in the face of what seems understood. The criticism being you provide no more than take my word for it.
Hello; The last comment you are using hypothesis and observation in a way far different from standard usage. To have a conversation we need a common language which is mutually understood. I cannot measure in inches while you measure in centimeters for example. We need an agreed upon set of meanings of words and cannot change meanings at will.
