I need help on a new tank....

[s17oopy]

Hello Everyone,

I just TOP up a new tank with DI water. I had tested with a TDS and the reading is zero.

So I add my media from previous tank, non live rock and sand which wash under tap water.

Before I want to add salt to mix.... I test the TDS reading of the current tank. It's 586..... No matter from tank or sump it's the same reading....

Does anyone able to explain is it normal?????

What should I do now???

I guess need to cycle the tank again but not as long as the first time

Bro, don't worry about the TDS for now.

Anyway, you should mix the salt water first, before you put in your LR and sand.

Thank you everyone for the reply. I will monitor and see if everything is ok.

The TDS reading should only be use as a guage for tap water reading, it is useless in saltwater.

I only check for TDS when I was keeping Crystal Red Shrimp in my freshwater tank. TDS is not critical in saltwater tanks.

TDS is critical when you do water change

Try do water change with TDS above 5 for a long period like 6 months 

and your tank will become planted tank
