Benificial bateria and Low ph water

Recommended Posts

hybird147

Hi,

As I've read on few online sources,which say that beneficial (nitryfying bateria) do not cope well with ph below 6. My tb tank's ph is around 5.4 -5.5, that has few berried and im getting some more stock in soon. I have not experience any deaths yet (WP is optimal). But Im feeling a bit off and worry about introducing more stocks around 10-20, and all the upcoming babies, that may cause sudden spike in NH3 and NO3 due to the fact that bateria already do not thrive well in my current WP.

Im thinking of switching using only RO water to 40/60 - aged tap water(with mosura shizhen)/RO water to bring ph up to 6 -6.2 over a course of next few weeks. With 10% water change every week. And increase dosage of shrimpbooster (from bossaqua) as this is the only additives I have that provide bateria. Id prefer to prevent any problem that may arise rather than dealing with it later on the way.

I hope some veterans here can give me some advice on these :). How do you deal with low ph?

Cheers and thank you

What substrate do you use?

I use Cal Aqua Lab Black Earth (new formula)

Initially i was going for Iwagumi tank, but then i found tb is more interesting so i switch over and didn't bother to replace substrate. Since the substrate is around 3 months old up until this day.

What is your Ammonia, Nitrite readings?

 

If it's 0, I wouldn't worry about it. It means you already have beneficial bacteria, and they are alive to process nitrogenous waste.

Many of us use Cal Labs Black Earth Premium. It's my favourite substrate at the moment.

At pH 5 or 5.5, the bacteria is less active compared to higher pH levels. But they are certainly still alive.

You'd only start worrying if pH was 4 or lower.

 

And pH 5-5.5 is perfect for the more sensitive Caridinas.

 

If you continue to keep TB, then the low pH of 5.5 is perfect.

 

And introducing 10-20 shrimp at a time would not be too stressful on the bacteria. They will just multiply to cope with the increased load. When there are more babies and an increased bio load, the bacteria will multiply due to an increase in food source (ammonia). But when there isn't enough food for the bacteria, they will die off. Thereby maintaining the perfect amount of bacteria to nitrogenous waste ratio.

 

At such low pH levels, ammonia and nitrite is not so toxic (ionised ammonia NH4+). In addition, ammonia toxicity increases as temperature rises.

Thank you @jayc. I never get any reading on ammonia. I guess i don't have to go an extra mile with mixing ro and tap water then :)

It's always better to use RO & Salty Shrimp minerals for the higher end shrimp, just takes one problem (what's in your water) out of the equation so you can focus on the rest of your WP. :thumbsu:

You won't have to.

Well said back @Squiggle :thumbsu:

 

Hybird147,

like Squiggle says, if you have RO water, stick with that.

Ye thats what im currently doing. I guess I worried bit too much about bateria. Lol.

As long as you add new stock slowly & you have a zero ammonia & nitrite reading the bacterial cycle is fine. :D

That's the least of your worries once you go RO with supplementary minerals. I'm constantly battling keeping my pH low (at 5.8-6pH) and lower my TDS (at ~400ppm) in a 3 year old tank.

Amoniac của bạn là gì, đọc Nitrite?

 

Nếu nó là 0, tôi sẽ không phải lo lắng về nó. Nó có nghĩa là bạn đã có vi khuẩn có lợi, và họ còn sống để xử lý chất thải chứa nitơ.

Nhiều người trong chúng ta sử dụng Cal Labs Black Earth Premium. Đó là chất nền yêu thích của tôi vào lúc này.

Tại pH 5 hoặc 5.5, các vi khuẩn này là ít hoạt động hơn so với mức độ pH cao hơn. Nhưng họ chắc chắn vẫn còn sống.

Bạn sẽ chỉ bắt đầu lo lắng nếu pH là 4 hoặc thấp hơn.

 

Và 5-5,5 pH là hoàn hảo cho các Caridinas nhạy cảm hơn.

 

Nếu bạn tiếp tục giữ TB, sau đó độ pH thấp là 5,5 là hoàn hảo.

 

Và giới thiệu 10-20 tôm tại một thời điểm sẽ không quá căng thẳng trên vi khuẩn. Họ sẽ chỉ cần nhân để đối phó với tải tăng. Khi có thêm em bé và một tải sinh học tăng lên, các vi khuẩn sẽ nhân rộng do sự gia tăng nguồn thức ăn (amoniac). Nhưng khi không có đủ thức ăn cho các vi khuẩn, chúng sẽ chết. Qua đó duy trì số tiền hoàn hảo của vi khuẩn với tỷ lệ chất thải chứa nitơ.

 

Ở mức độ pH thấp như vậy, ammonia và nitrite không phải là quá độc hại (ion hóa ammonia NH4 +). Ngoài ra, độc amoniac tăng lên khi nhiệt độ tăng.

If ph 5.0-5,5 better for twb shripm then how much GH ??? My shrimp tank ph 5,2 gh6 tds 140 shrimp color very bad.

Those parameters are fine

higher gh should make ur bluebolt color better

but right now at gh 4 tds 120 (different soil different gh buffer, amazonia got lower gh)

i see the blue bolt color still good,

i had experiment from tds 90-160 and i see best color at tds 140 (gh 5)

 

ofcourse it would be different if we talking about redwine

      My brother just moved from San Antonio to Florida! It may be more economic to purchase a specific chiller for the shrimp tank, we don't have that problem here though I did cook mine, 33 degrees if I remember, d'oh (faulty heater)! I assume you can get one for a large tank like yours? There are a number of foods that are probably easier and don't go mouldy, like snowflake which is soya bean husks and can be left in the tank for long periods and is therefore better if you are going away for a period. Indian Almond leaves are good for holiday periods as well because they decay very slowly and 'stuff' the shrimp like grow on them. Probably if you are just going away for a few days you may be better not to feed and if there are Indian almond leaves etc in the tank they should have enough to eat. Hopefully you caught the temperature in enough time that you won't loose any more shrimps. Simon

      Yes. I live in Texas. When I'm away freon the house I'll have only one of my AC units running so the cats don't die.  The mold was caused by some food the shrimp didn't eat.  I did a temp check with my other probe  and it was almost 2 degrees higher. I guess I'll leave the fans on when I leave now
    • sdlTBfanUK
      I would think that is possible as that is pretty much the upper limit I think, and of coarse how accurate is the thermometer - I have 4 different methods and all produce different readings so it may have been a bit higher??? Mould isn't usually a problem other than it looks horrid and usually will just disappear after a tank is properly run in and as far as I know not harmful to shrimps. I have had it in most of my tanks at the start, usually on wood or something similar and either removed the item it grows on or just leave it and it gradually disappears within a month (usually less). I hope you manage to get the temperature back to normal and it sounds like you have mastered the TDS. I'm not sure where you are based, is it somewhere hot (I apologise if you have said and I have forgotten)? Simon

      I came home from being away for 2 days and there was another adolescent shrimp dead. I saw the water temp was 83. I know they like to have 70 to 78. Would 83 kill some shrimp?  Also I first started doing water changes again and I had to do a little extra a few days later because there was a little mold I had to siphon out. Not sure if that's the reason either. Also my water TDS stayed between 142-147 this whole time.

      The tanks are only 16L, for it to reach 31c, it isn't hard.
