has all the ferts disolved?i use 10tsp in 900ml of water and they all dissolve ok,may be worth adding more water if they havent disolved,just remember to dose more to get the required ppm.

Hi there,

I have been using ferts via EI protocol as described in this link: http://www.ukaps.org/EI.htm. Basically I prepared a 600 ml solution for NPK and a 250 ml solution for CSM+B. I am dosing 25 ml of NPK 3 times weekly and 12.5 ml of CSM+B twice weekly to my 10 gallon tank. This morning, however, I saw floaters in the NPK solution. I am pretty sure they are bacteria colonies. I keep both solutions in brown glass bottles to protect them from light. I used distilled water to solve the powders about 3-4 weeks ago, and I am still using that original solution as above. I neither filtered the solution nor boiled it after preparing it. Was I supposed to do such things to prevent bacterial colonization? Or should I just relax and keep dosing? This situation worries me, because I don't want to inject a solution with colonization of unknown bacteria in my tank. I just lost one of my Harlequin Rasboras due to a possible bacterial infection on top of everything. I don't mind preparing a new stock solution, but it will get colonized eventually, too. So, what would you recommend?

Any response will be greatly appreciated.

Hi,
Well for one thing you can stop using distilled water and use tap water instead, which is chlorinated and which may help delay the onset of spoilage. You can also think about adding a few drops of muriatic acid or other strong acid to the solution when preparing it. You can also keep the solution refrigerated.

In any case there millions of species of bacteria and I doubt that the species in your NPK bottle are the same as those that attack your fish. Bacteria do the work of detoxifying your tank, remember? So lets not get on a bacteria bashing witch hunt. :shh: It might not even be bacterial growth, it might be fungal.

Cheers,

Hi hakova

Just my experience.
I dose EI like yourself and I use tap water and I've never had any fungus or bacteria issues. I only mix up enough for a 4 week supply and keep it in clear bottles in the cabinet under the tank :wideyed:.
No fridges or cool cupboards for me.
About all I do is keep it in the dark :D.
Just a suggestion, my maths tells me that your 600ml @ 25ml per dose is 24 doses = 8 weeks supply. Maybe try reducing your volume to 300ml for a 4 week supply and see how that goes. Then you have fresh water in your mix every 4 weeks instead of 8. Might solve your problem.
Certainly works for me :D.

Thanks a lot for the replies.

@ceg4048: Excellent article on EI dosing, very easy to understand and apply. I appreciate the inspiration that made me chose EI path over others. And you are right, no need to do bacteria bashing witch hunt; just two events coinciding on an anxious fish tank hobbyist :lol: .

@chris01: I was thinking about exactly the same thing. Thanks a lot for the suggestion, will definitely prepare the new batch that way tonight.

BTW, I didn't intend to hijack the thread, the subject was exactly what I was going to post on, that was why I posted at the first place. I am sorry if I caused confusion and trouble.

No troubles at all mate. It's a good thing to keep various aspects of the same issue together. Makes it easier for folks to access the data. :D

I use tap water with my mixes and never had a problem, I mix 1.4l of water with the dry salts and last about a month, does not settle or become mouldy!! ;) I followed JamesC recipe!
