Amanos unhappy and breathing heavily after EI dry fert dosing
Hello everyone. After having an inexplicable mass die-off of my 40 amano shrimp in my aquarium a couple of weeks ago, I introduced 2 new amanos in the tank to make sure that everything is going ok and that the water is ok for them. They've been with me for a week now, and so far they've been doing well. However, when I had a look at the aquarium about 2 hours after having dosed my fertilisers for the day, both of the shrimp were breathing rapidly and did not look happy at all. Let me give you the specs of the aquarium:
It's a 180 liter aquarium, 100cm L x 40cm W x 45cm H
Inhabitants are cardinal tetras, otos and the amanos
2 x 45W fluorescent tubes that are on for 6 hours daily
I'm injecting a fair amount of CO2, the drop checker shows green to light green
It's an iwagumi style scape that only has Eleocharis parvula
kH:11 degrees ( I believe the test kit is giving a false result; according to the kH/pH/CO2 chart, nothing would be able to survive in the aquarium)
I'm dosing according to the EI and change 50% weekly.
All of my fertilisers are dry apart from Seachem's liquid Iron fertiliser.
I really am at a loss as to what might be happening. I was planning on getting more shrimp for the tank as 2 are not even close to being enough, but now I'm worried of losing them all again. When I had them previously, none ever showed any negative response because of the fertilisers. The only thing I can think of that is worth pointing out is that today, as I was not very focused on what I was doing, I dosed both Phosphorus and Iron instead of dosing them on different days. If anyone has any ideas or similar experiences, do let me know, I really am worried there is something that I'm not quite getting here...
