pH and the other parameters will naturally tend to fluctuate alot during the initial tank startup and cycling period, especially when active soil are used. Just need to give everything time to settle in and stabilize properly.
PH dropped back to 5.6 this morning when I tested. That's a 1 point drop in 5 hours. Going to test again tonight after work if it drops further. Ammonia and Nitrite remains same as previous test. <br /><br />Sent from my SM-N9005 using Tapatalk<br/>

Thanks fur the advise. Just worried the low PH will make bacteria dormant and stop cycling

Low pH does inhibit the growth and efficiency of some bacteria, but the ammonia and nitrites are also in non-toxic form so its a trade-off. Thats one of the reasons why some shrimp keepers just add their shrimps in after a few days (sometimes even immediately after setup) and don't encounter any issues... but the key is to keep the low pH stable for that to work, if chemicals or buffers are added or water changes are done and the pH fluctuates, all the other parameters will start to change and that's when the shrimps get affected.
Agree Urban Aquaria. That's why think it's safer to have it cycled just in case.
Just wondering aloud, shrimps are said to be no or minimal bioload so they release very little ammonia. A fully cycled tank will requires a good source ammonia to keep the bacteria well fed or they will die off. Find it contradicting here.

Guess my ph is very stable. Its back to 4.7

Well, a fully cycled tank is deemed as one which can handle the existing bio-load and convert ammonia to nitrates as fast as its created. The initial cycling period is just to allow sufficient populations of bacteria to establish well enough to be able to grow readily anytime to respond to any changes in bio-load.Originally Posted by burp
The various bacteria populations will naturally increase or decrease depending on the bio-load, so even in a fully cycled tank, fishes and shrimps should still be gradually added in stages (not all at once) so that the bacteria has time to multiply to match the waste processing requirements.

Added 5 low grade CRS from CRS Haven to test the water. Hope the commando shrimps can survive.
So far 3 are slowly moving around exploring the tank and picking up what I believe to be biofilm. 2 have gone into hiding. Very tempted to dig them out. Lol

Day 3: one casualty. Other 4 doing well still. Probably the water change last night stressed it to death. uploadfromtaptalk1403531541598.jpg

Can share damage of your low grade crs?

My ph is alright. .but nitrate suddenly shot up today..no spare tank. .so did water change. .plus add abit bateria..hope it works. .

$3.50 each at crs haven.

all the best! how it turns out fine.

Just an update. .1 did not survive the acclimatisation. .
Fire red?

Nice. I love rcs. Wanted to have some in my new tank but lfs said my 5.5ph is not suitable.
Sent from my SM-N9005 using Tapatalk
Mind's a community tank. .sharing with tetra and 1 yamato. .ph measured today with test strip was at 6.5ish..
Anyone can id the breed?

The RCS in your photos could be considered low grade fire reds (which are the ones commonly pre-packed in bags)... btw, if you are keen on selectively breeding them to improve the offspring quality, the one in the 2nd photo should be culled or transferred out before it berries.
Hmm. .but I dun think I even have a male..based on the sexing guide..my specimens are all well colored...
Sent from my SM-N9005 using Tapatalk
Just have to observe them closely, the ones with saddles would be confirmed females, but there is a chance those without saddles could be males. Sometimes there are also male shrimps with good color too, they are usually visibly slimmer when compared to the female shrimps.
Yeah, i do notice there is a higher tendency for female shrimps to be pre-packed into the "fire red" bags due to their better colors, on the other hand the "sakura grade" or "bulk grade" bags tend to have alot more male shrimps due to their more transparent color... i always have to specifically select and handpick the male shrimps that have good color directly from the LFS shrimp tanks.
Can I go go LFS and like tell them I want a male? Lol
