Welcome to the forum
You can also tell us how the algae/stuff acts.
If it is only on the floor, it can be pollen or algae.
only on the floor
If it is on the wall, it is algae.
Is it yellow or greenish/yellow? When you brush it does brush off easily and make a yellow dust?
greenish/yellow/grayish/brown LOL. brushes easily, i can actually just get close and the water moving causes it to make a dust, I'd say the dust could be yellow but id call it closer to brownish
Waiting for full set of water test results
I have been testing but I'm embarassed to say with strips. I just ordered the TF-100. Shouldnt take long since I'm only 30 miles from Duraleigh.
