Hi all,

I would like to know how to lower ph in biofloc tank during water preparation. My initial ph of water was 8.8 after aeration it's 9.2. what should I use to lower ph which is safely used in aquaculture. Alum is toxic to fish hence have to be used with caution, vinegar I tried once but then slowly my ph goes back to 9.2. Kindly suggest me any organic or organic fertilizer. Carbon source jaggery I can't add in large amount add the volatility. Inducing co2 is not cost effective in India.
Hi Sir,

Can you please let me know how to lower ph from 9.3 to 7.5? Using CO2 Gas is not cost effective. Sodium bicarbonate Lowers and adjust Alkalinity but not effective. Acetic acid lower but slowly gets back to actual ph. alum can lower but toxic to fish. There are cottonseed meal, soybean meal and cracked corn don't know how effective it is. Request your guidance.


Thanks,
Raji Panicker

In order to maintain 28 degree temperature in bio floc - mainly in winter - we have to enclose the tanks in packed shade or poly house . It is also said that if I maintain C: N ratio of 15 :1 by adding sugar (Carbon source ) in tank there is no need to add any probiotics -I want to know the facts
