Great discussion on water changing methods

Hehe, good one Theo! :roll:

Yeah, i think i'll get some of those plastic fish..... :lol:

Nah, the oxidization via ozonization method is the easiest for me, works fine too. Been doing it a while now, the ozone renders everything useless eg. chloramines, chlorine, ammonia, nitrites, nitrates etc. by passing off an oxygen molecule to all chemical compounds it comes in contact with (see above list), this is called oxidisation, rendering all the compounds inert. By then carbon filtering, the inert compounds are removed from the water, leaving you with quite pure and clean water. Add some trace elements, salts, buffers etc. and your away!

I ozonise for 24-48 hrs for a 240 litre drum, depending on how shitty the water is, then i carbon filter for 24 hrs, adding salts, buffers etc takes 2 mins. Alot quicker than waiting weeks for plants to absorb nitrates through photosynthesis.

Carbon is cheap, as are the Resun Ozonisers (approx. $149). Almost like RO water at a fraction of the price!

guys i agree with all of what you are saying but really do you think we are going to far with what we do to the water??

fish are pretty tolerant  and can put up with a far bit......do you really think the water is that good where they come from.

just for example

im sure for one reason or another the ph in L Malawi is not a constant 8.2. rain would effect that like many other things would.

also like uv's, if your using one is your water so clean that when you sell fry or even older fish to someone who isn't it can be to much of a shock to the system.
 im not knockin you for what your doing, its just do you think we're going abit over board....

20 even 30 years ago none of this had been thought of and the yellows were as yellow, prob more so, then what they are today, lived as long and breed the same, so whats the advantage????

20-30 years ago the water out of the tap was fresh straight from a natural dam or river etc.

20-30 years ago our councils hadn't discovered how to go overboard with chemicals to make fresh water not so fresh anymore.

20-30 years ago people got by without chemicals in their tap water, but our councils seem to have forgotten this.

By doing what we're doing we're trying to make the water like it was "out of the tap" 20-30 years ago.
