Talking Paramters: Never fails to amaze me

Time & again it amazes me how I can have numerous tanks set up with the same source water, same plants and even the same substrate used. Yet during/ after cycling each & every tank is always different

Here's a comparison from my 45 vs 10g tanks

Start for both tanks KH 1 pH 6.8
21 Nov: 45g KH 2 pH 6.8
21 Nov: 10g KH 7 pH 7.8

29 Nov: 45g KH 2 pH 7
29 Nov: 10g KH 5 pH 7.6

6 Dec: 45g KH 2-3 pH 7.2
6 Dec: 10g KH 5 pH 7.6

That would be because of your low KH. I would expect GH is low as well. This refers to the waters buffering ability, its ability to resist changes. Your water has very little so it will change very readily to small changes. I would be careful with that. Don't try any DIY CO2 as your pH will probably drop a lot especially in the 45gal. The 10 is better with the higher KH, but still IMO something to pay attention too.

Why the ten gallon is higher may be due to amount of substrate per/ gallon. Do you know if the tanks are the same? Gravel would be expected to increase pH. The cycle will also lower pH slightly, usually we don't pay attention to this. Yet with your soft water.... is the 45gal stocked any heavier than the 10gal? Drift wood in the 45 gal?

Running crushed shells or coral will help IMO. It will raise your KH and reduce the fluctuations. Your pH will also rise.

I know Mikaila....I understand the reason's why, but it always amazes me. Even the old tanks when I had 7 up at one time (and hard water at old location) EVERY tank had quite different pH & KH readings after they were established.
I left the 55g out of the example (whole nother story lol) but I am sure the reasoning these 2 are different in KH so far is substrate, while the 10g has fine black sand and the 45g has fine black gravel both same brands. The amounts used are more or less the same in either case per galon (I hadn't really EXACTLY measured it, but by eye sight judgment +/- lil bit the same lbs/gallon).
10g & 55g aren't stoked at all yet and th 45g has a "starter troop" of 5 Rummy's atm (they will get stocked to a school soon).
ALL my tanks have large pieces of DW, I generally try to add DW that is in relation tot he tank size about 1/3 in its size.

Naw I'm not adding anything at all now, I wanna see first after they been up & running for let's say some 8+weeks how they establish themselves then with the readings and then go from there. Doing something now while the tanks still are leveling themselves out would be too early and I also don't want it too high because of the Tetra's. And like I said, based of the old tank, I really don't expect any of them current 3 or any tank to follow having the same readings ever. So I'll go from there and do what I have tank by tank over time.

Wouldn't plants alter the readings as well there Angel? Depending on the plants in your tanks you may have different readings... and I'm not saying that would be the only factor but I'm fairly certain that it's part of it... different plants are bound to give out different amounts of CO2 and whatever else during photosynthesis no?

But I hear you... it still blows you away how nature reacts!

Well yea it def would, specially the NO2+3, or if I had zero plants vs overplanted tank, then I could see this. But as far as hardness, the main driver there really is the substrates used. And yes they all utalize the nutrition in the tank in different amounts, but there you're talking about levels that differ SO FINE that I donno if my test kit would pick that up really.
Main drivers for ph & KH in tanks is really the DW size's (lowering your pH a little, or a lot) the substrate and rock decor.
