Whats our TDS of our tap water??

[Numbskull]

bought online and got a TDS meter shipped over today. tested out my tap water and TDS was at 70???? Anyone can give me a rough gauge of our tap water tds??

[eviltrain]

my location is at chai chee. the tds reading is 100

[Numbskull]

Thanks Evil. I'm at AMK anymore reference from hobbyist here??

[ZackZhou]

me amk too. tds around 80.

[eviltrain]

We should be happy that our TDS is very low. hobbyist in Germany have rocks floating in their water. hee hee

[felix_fx2]

Tds means what ? Pardon my ignorance, I'm not the shrimp guy.

Btw. Floating rocks? Like dead sea to me hehe

yeah sure.......last time i check TDS at china town around 74 ppm........

i thought singapore would be very good for the tap water...in my place in jakarta, my tap water around 170++ppm and the water couldn't to drink. so we must buy the water for drinking and the water for drink i tested is around 55-60ppm. so i thought singapore tap water already passed through good filtration that's why below 100ppm i thought already good.

here's a tabel to see what kind of TDS is good or which is mean for good or bad to measure TDS.


It is a measure of the amount of magnesium (Mg +) and Calcium (Ca +) ions in water. When we refer to water as a "soft" or "hard," we refer to the GH. This is measured in degrees of hardness Germany (dH). One dH is approximately 17.5 mg / L (ppm).

Table GH:




Understanding GH general hardness table / KH / pH / CO 2 to aquascape / Shrimp

Carbonate hardness measuring the amount of carbonates and bicarbonates in the water, expressed in degrees of German hardness (HPD).

The term "hardness" in KH is somewhat confusing because it does not actually measure the hardness, but the alkalinity (buffer capacity - the ability to neutralize acid) of ability to resist changes in pH. The higher the KH the more stable your water and getting more robust in the face of pH swings. Parameter 2-3dKH generally accepted as the minimum value to obtain a stable pH.

Nice info bro Zack, very useful for me. Thumbs up

Nice info bro Zack, very useful for me. Thumbs up

yeah sure, it would be nice if i can share something useful for other people

but that table isn't completed yet i will make it completed for everyone to understand what kind of relation with TDS and with the water parameter.

this is the rest of information :

pH (per hydrogen)

pH is a measure of the balance between hydrogen (H +) and hydroxide (OH) ions in water. The pH scale value from 0-14. As we know, the pH value of 7.0 means that the pH is neutral, with readings from 0 to 6.9 as the acid, and a 7.1 to 14 bases.

pH also serves as a center of concentration of KH and CO 2. That is, we can determine the amount of CO 2 (mg / L or ppm) in water if we know the value of pH and KH. In its application, the pH will fluctuate when we added CO 2, while the KH remains stable.
Carbon Dioxide (CO 2) Carbon Dioxide (CO 2)

Carbon dioxide is not mentioned in the title of this article, but also part of the water chemistry is very important. CO 2 exists in water in concentrations far greater than the combined oxygen and nitrogen (70:2:1). We Often think of injecting CO 2 to increase is the growth rate of plants in our tanks. We often make additional supply of CO2 in the hope that the plants will grow fast and lush, but actually we also have to understand the relationship between CO2, KH and pH.

Without too much detail into his chemical processes, when carbon dioxide dissolves in water, it becomes carbonic acid, increasing the amount of acid, and lower the pH in the aquarium. Total carbonate (KH), which is in the water will determine how far the pH will drop.

Below is a chart of the relationship of pH, KH and CO2:



Adjusting GH / KH / pH

Because the relationship between the three aspektersebut, applying the method to decrease or increase one aspect usually would have affected other aspects. In the table below, there is an explanation how or the most common methods to reduce / increase the GH, KH, and pH.

wa~, mod should make this a sticky!

thank bro zacks

[Numbskull]

alright so i guess TDS in our tap water is very suitable for shrimps since CRS mostly needs 175-225 range.

Bro Zack, once you had completed your table, please inform mod to make your thread a sticky since i believe its very useful for shrimp hobbyist.

From the GH table, 175-225 will mean a GH of 8-12dH. Is this range of GH suitable for CRS? My current tank is at 10GH with a pH of 5.8. They are fine so far just that do I need to adjust my GH as I was advised that too high a GH like 10 may make their shells too hard for them to molt?

Bro not sure if I am right, I read somewhere that tds also measure other dissolved particle like nitrates, ammonia and stuff. So a high tds might not solely contribute to gh only. So do be a little careful

Mine is 70.

[jjchew]

Cck 70.......

[newlife]

Zack...thanks for the Great info even though I don't know what the heck the chart is telling...
Ps Ps...No study...don't understand much about chart reading and water formulation...
