0.3 salt level? Can't Post
hi
I have a digital saltmeter which measures up to an accuracy of 0.01. My question is: do we have to be accurate in maintaining the salt level to 0.3 as commonly referred to as a benchmark or standard?
How about 0.2 or 0.1?
What happens if the salt level is beyond 0.3 say 0.4?

Thanks in advance.
Dennis

Please read this thread

http://www.koi.com.my/ubb/Forum9/HTML/000002.html

BTW, your 0.3 salt should clearly write as 0.3% salt.

hi Khoobg
You are right it should be written as 0.3%.
In your thread you have just given, one of the postings mentioned that the salt level should be reduced after a few weeks time so as to prevent salt-resistant bugs. Is this necessary to reduce the salt level and then increase again in near future?

Yesterday I have increased my salt level from a constant of 0.17% to 0.3% now. I am confused if I should let it remained at 0.3%?

Any advise is appreciated.
Thanks
Dennis

Dennis,

As you are still facing problem with nitrite, salt of 0.3% will prevent nitrite poisoning. Once everything is back to normal with active koi, you should reduce the salt contents. A slight percentage of salt will prevent illness while too much salt will result in salt resistance bug.

hi Welson
Thanks for the advise. How long should I maintain the 0.3% salt level? How about later when i reduce the salt level say to 0.2%, will this level also prevent nitrite toxity?

Thanks
regards
Dennis

Hi Dennis
If you are constantly changing water, there is no need to maintain a 0.3% salt level. Your problem has got alot to do with water management and not sick fishes. So I will recommend that you move some of your fish to the farm or "tompang" someone till your filter system works properly.

hi Mark
I just cannot seem to get my ammonia and nitrites levels down. I have sent you a diagram of my tank. Hope you can kindly advise me what to do next.

Can you help to post the diagram so that others may learn too?

Much thanks!
Regards
Dennis

Hi All
The drawing above is a filter system incorporated in a pond/tank - ie built-in filter system.
To maximize and encourage bio bugs to grow on a larger area it is recommended that either synthetic media or heavy brushes be put in the 1st chamber. In this small system synthetic media will be more effective - firstly to trap the heavy stuff and secondly it also expands the bio surface area. I am not sure if there is a built-in backflush system for all chambers and especially the first. Otherwise DIY one will be extremmely helpful. Synthetic media at 2nd chamber should be loosely packed to encourage free flow of water carrying the toxic stuff for easy "good bugs" conversion. It is highly recommended that a bag of at least 10kg of cockel shells, oyster shells or coral chips be put at the last chamber to buffer pH. The submersible pump is moved from the first to the last chamber so that either a venturi can be connect at its output or redirected to a trickle tower.

Unfortunately Dennis wrote to me telling me that he is not a DIY man. I am wondering if there is anyone out there who could help Dennis.

Regards.

hi Mark
I checked my ph yesterday and it was 4.5! I quickly added baking soda till 6.0 and then waited for a few hours and raised it to 7.0 today. Apparently the water looked crystal clear and I happened to test the ph yesterday. Thankfully, the kois are none the worse for it.

Thanks
Dennis

another question - will salt level at 0.3% kill good bacteria as well as bad ones? Can the reason for my PH at 4.5 is the result of me increasing my salt level from 0.17% in recent week to 0.3% now? If the present salt level of 0.3% is not good to mature the filter box, should I revert back to 0.17% level?

Thanks in advance
Dennis

For now you don't have a choice but to have major water change immediately and maintain the 0.3% salt.

Went over to Dennis' house this afternoon and witness his new filter construction was as diagram. Installed a trickle filter for him too. Hope his filter problem was solved and he can enjoy koi keeping better.

Hi All
Since this thread is about 0.3% salt shall we continue with the discussion on filter modification here.
