How do you keep feathery plants like myriophyllum dust free?
I keep getting light brown dust (I’m guessing from the substrate?) on the leaves. It just feels like biofilm when I rub it off, not like diatoms. Maybe it’s just a type of algae...? I use Fluval stratum.
I have three Amano shrimp, 6 blue velvet shrimp, a nerite snail, and 7 Pygmy corydoras. The shrimp aren’t adult sized yet and they tend to eat some of the food I feed to my Corys. I was thinking of getting 10 more blue velvets but more so to build up a colony rather than the goal to address the dust issue.
It’s a 10 gallon tank with a nano sponge filter from the co-op.
I have a Chihiros C2 at 60% on a timer for 10 hours a day so I’m wondering if I should up my fertilizer. My nitrates have been between 5 - 10ppm. I was using NilocG Shrimp formula but recently switched to Easy Green. I’ve been doing a water change the rare times it reaches 20ppm but I’m wondering if I should leave it until it reads over 20ppm...? I’m concerned that’d be toxic for my livestock though.
This is a photo where I tried to rub most of the dust off but there is still some on the edges of the leaves.
