Hello I am just getting started with dry ferts (thanks to Orlando from GLA) and now going to use the PPS Pro Solution. I will be using a 500ml bottles to mix in (macros and micros). The question I have is how long is the mix good for once I combine each of them in the bottles? Do you need to refrigerate or anything special with it once it is mixed?

x's 2 Freydo. I just keep mine in a dark bottle to keep light from penetrating and then keep that stock in the fridge.

Btw - My bottles are just hydrogen peroxide bottles.

Hi jeepn4x4,
I mix up about 2 weeks worth at a time. When I first started dosing, I used tap water. After a week or so fungus would appear in the solution.
Now I use distilled water and store at room temperature in old Seachem bottles that I saved. I add a couple of drops of fungus treatment to each bottle as well.

The CSM+B tends to get fungus quite easily. I keep both solutions in the fridge but the CSM+B will develop fungus after about two weeks so I make it up in smaller batches. I haven't tried the fungus treatment.

Fungus??? Re: PPS-Pro recipe storage

Did the fungus in the micro solution cause infection or problems with the fish in the tank? My cardinals have come down with what looks like a bacterial infection and some with perhaps secondary fungal infection. My solutions have been mixed for about three weeks. I did not see this thread when I mixed them. I use peroxide bottles and store in refrigerator. I just pulled out the micros and it looks like maybe there is some kind of contaminant - tiny threadlike possible fuzzy lint sized particles.

I see the reference to a few drops of anti-fungal. Are we talking methalyne blue?

Opinions?

I started treatment with melafix and pimafix.

My macro solution has brown, cottony fungus type bits floating in it after about a month. I used RO/DI, it's in a white bottle under the cabinet.

Should I toss it?

Hi jaidexl,

I had a problem with fungus in my ferts as well, my trace mix was the most susceptible. Now I try to mix up no more than I can use up in about two weeks. I also changed to distilled water instead of tap water and I add a few drops of fungus medication to the mix.

I used RO/DI and only get a few weeks of use out of it before noticing the issue. :(

I guess I'll try keeping it in the fridge next time.

I never got around to making the trace mix, waiting for a particular bottle to become empty, still dry dosing micros till then.

Maybe I should just continue the dry micros then, it's easy enough to do anyway. Makes sense to do the work of mixing all the macros for an easier regime (disclaimer: easier for some of us), but it sounds like it was all in vein for those that got fungus in their trace. I'm betting my luck will give me fungus in my micros as well.
