When I fed my shrimps on saturday I counted 80 and yesterday all appeared well also.
This morning all I can see is dead bodies with a reddish colour shell to the head area.............. I assume it is rust but am not certain, only going by what I have read here.
From what I have read here it could be because the substrate was exhausted and the PH had risen to 7.5 last time I checked (though that was slowly over time)?
I doubt there is much I can do at this stage, but I will set up the old 15L to put any ALIVE healthy looking shrimp in IF THERE ARE ANY! and close down the big tank and start again. I guess I know next time that when the PH indicates that the substrate isn't working properly to act quicker???? When does the learning finish!
My main queries at this stage are:
1) Is it safe to put stuff from this tank with the dead shrimps into the small tank where I will put any healthy shrimps (If there are any alive that is) or will that be a bad idea, I am thinking, water, heater, maybe a plant or 2 etc.
2) How do I make the bad tank good now so that it won't be contaminated for the restart? Tank, filter, heater, plants, decorations etc. I will use new substrate.
