As fish keepers I think we are mostly interested in how saturated our water is with oxygen, the best way to measure is with a redox probe, the higher the number the more oxygen is being absorbed by the water. I am pretty sure conductivity is closely linked or the same but my nitrate filter used to run at -170 and my tank is 200-300
What do you know or understand about REDOX?

Toby- Isn't a nitrate filter just a place for aenerobic bacteria to dwell, and in turn must be void of O2?Or am I misunderstanding something? Also can you tell me exactly what a HMA filter consists of? I know there's carbon, but what else? Is it the carbon that kills the metals or is it something else?
I'd like to know the relation ORP and conductivity. For some reason I was thinking TDS is related to conductivity. Is conductivity what you want to watch as it's a better overall picture of TDS?
Obviously I'm clear as mud on this stuff.
And Keepin..... The Aimara is a very misunderstood fish. Like comparing a pit bull raised with children, friendly and trustworthy, to one bred to fight and eventually kill. I could see the similarity with juvies and walleye. But Aimara don't get their curves till they get bigger. Mines just starting to fill out at about a foot. They're tough as nails and recover so fast. Like a puffer or rays they're always very quick to greet you at the front. Get the siphon out and they're just a ball of fire....lol. Hard to describe them, but at least the worry level with them is nothing compared to an Armatus. For some reason I just see fish like ATF and Armatus to be skiddish and carry a higher stress to owner value then something tough like Dorado or Aimara.

TDS a higher number means that the liquid is able to carry a voltage better because there are more things inside for the electrons to bounce between. Its why distill water is not a very good conductor of electricity. Redox refers to the ease of a atom to pick up an electron as in how able is it to take another electron from another atom increased reduction means it is more able to take an electron. Since these atoms that are reducers once they take the electron away their octet or outer most ring of electrons is now complete and the atom will no longer react with anything else for a reference look up noble gasses. I believe what a uv pretty much does is, enters more energy into the atoms that act as reducers as electrons gain more energy they get excited and move around more in their orbitals. So now instead of having to replace the atoms you are recycling the old ones by forcing them to lose their electron that they gained and causing more reactions to occur via increased energy from the uv.
Hi Db, yes a nitrate filter is anearobic but not totally devoid of oxygen or at least there are levels, the reason I gave up on the nitrate filter was that it was a constant juggling act even when fully automated. If the orp dropped below -200 (redox) then it became a sulphur factory and the effluent would turn the water in the tank cloudy, not to mention the rotten egg smell. Above -150 to -100 the bacteria got some air and therefore started to produce nitrite...... I had a redox probe monitoring and then a dose pump putting in vodka mix to suit.
The redox is measured in conductivity in the probe using a simbol that I cannot find on my iPad but it looks like a u and a v together lol this is essentially a measurement in millivolts across a fancy electrode.
I guess it depends what you want to know, if it is how clean your water is then used tds as in total dissolved solids (crap in the water) but if you want to know how much the water is saturated with oxygen or lack of then use redox, both are different and use a different probe to measure conductivity, for instance the redox probe has a precious metal and salt in it. The aquatronica can measure both and knowledge is often power!

I do not know what is in an hma but there is carbon and then there is carbon. I have looked inside the 3 pods, one looks like a very very fine filter which I think is a particulate filter, the next is some sort of membrane like RO and the last is a high grade carbon....maybe not in that order.
From Devotedly Discus site:
The pre filter will remove sediment down to 1 micron. The middle pod houses a "Chlorplus" cartridge which is a very high quality filtartion component. It' smain purpose is to remove Chlorine and Chloramines. The final pod houses the HMA cartridge.
The HMA cartridge will remove chlorine, heavy metals, and certain volatile organic chemicals(VCO's)
