Ehhhh copycat!

You need to cycle firsr. But there is way to shorten the cycle time  by
- use old filter with media, and or borrow filter floss and media.
- use tank water from an established tank.
(The above two method will transfer any disease/pest between tank if any)
-dose bacteria powder/liquid.

In my case. Im rescaping and reuse the old filter and since it is sand only substrate without soil that release ammonia.  I can put in shrimp on shrimp day.
As a precautions.  I do check for ammonia and nitrite after 3 days.  Before that dose 5x seachem prime amount for my tank size . Just in case to bind any ammonia or nitrite that exist.
Cos there is still risk of old beneficial bacteria can establish back in new parameters.

Seachem Prime more expensive for a reason, it can act as an emergency solution to counter ammonia and nitrite in uncycle tank with shrimp be put in that have no other mean to be transfer out. Instead of waiting for the shrimp to died one by one , we can dose 5x amount of Prime from normal dose
to bind ammonia and nitrite to non-toxic form, the best part is it won't remove them which are good cos the tank cycle can still continue.
It will be effective for one week before re-dose.
I have tried with one tank with a nitrite reading of at least 5ppm, with overdose prime, none of the shrimp died or behave unnormal.
Of course if possible don't resort to this method as risk is still there.

A week is too early. Maybe 2-3 week if everything new, as bacteria is slow to build up. Of course it help with frequent dosing of stability.
add in air pump to provide more o2 and temperature of 27-30c will be ideal to accelerate their grow. Light should on at least 8 hrs.
  I notice any soil based substrate will still leech ammonia no matter what brand. Although at low ph those ammonia are in less toxic form.
  That why normally with soil . It is more easy to kick start the cycle since ammonia is already present.  With sand or stone substrate.  You need to add in fish food or pure ammonia liquid to compensate.

To remove tannins effectively. Use seachem purigen. Put it inside fikter compartment.  Active carbon you may want to give it a skip when tank is still cycling.

No need , just goto your local fish shop , buy some ADA soil loose pack 250g, 500g or 1 kg , get a filter mesh bag , fill up with the ADA soil , hang it inside your tank 'woop' you got your ammonia source, clean and easy. when tank cycled, just remove it and put it in your house plant pot.

any aquarium soil will do, even shrimp soil also leech ammonia. Gex soil should be available in taiwan.
Fish food will pollute your tank if you can't control your hand.

Came home saw the tank water is clear....i remember read sumwhere to change 100% for 1st time, so did 100% water change.  Now cycling it again. Will change 50% tomorrow till end of week.
Meanwhile, malaya is living in 3ft castle...lol

wow nice tank
what plant you used for carpet?

Nice tank you got there bro. What's that black bag hanging at the back of the tank?

hmmmm, what is in the bag? soil?

Is it good not to have ammonia?

No, ammonia, got nitrite(NO2) detected ?
Yes, they very fragile when/after molt, if get jumped, they probably died. Yamato like to do that on other shrimp.

You using what substrate in the new tank? black pearl?
Plant like ammonia, those are nutrient to them.
The best is ADA soil but you can't find.

got No3 nitrate!!, seem like cycled unless your tap water full of nitrate in the first place, you dose alot of bacteria powder/liquid or
borrow old filter media?

oic, anyway for the new tank, beside checking for ammonia, after 3days can also check for nitrite.
Some of the tank i setup with old filter, it jump to stage 2 cycle after 2~3days.

I would like to share picture here but somehow cannot download using normal practise.

Planaria is bad , many more must be inside.
