At first my tank had low GH after I removed the driftwood wood and my Caridina shrimps died. After trial and error to see what caused the GH dip, it turned out to be the removal of that driftwood.
That driftwood wood is much darker in color than the other driftwood I had. It reeked around GH 5...
I manage to found another one but this time it has antennae and hair/legs (see attachment). I think this is the adult form. It looks like a sibling of the Daphnia, they have the same curled fetal position like Daphnia.
Yep, I was trying to reply to that post in particular.
No, plants will thrive because you have a lot of ammonia, nitrite and nitrates. After getting the nitrites and nitrates from bacteria, they have to go somewhere, which is to plant intake.
This is good, it's getting less which means the your first cycle is coming to an end. Do you have plants in the tank? Plants will take up ammonia and nitrite, which explains why your nitrite and ammonia levels dropped.
Your ammonia, Nitrites and nitrates should not be zero after 18 days. Especially if you have snails, because they poop a lot.
I think it's because you didn't feed the snails. Snails don't really eat algae, they eat rotting matter. Surprised that you didn't realized your snails dying as well, as...
I suck up a diatom using a pipette in my shrimp tank and put it under a microscope.This diatom is everywhere no matter what habitat it is in. I found also some flourishing in my Nitrite container with no air supply feeding only on algae.
