i just wanted to bump this thread back up and do a little update.
currently im having a little bit of an algea outbreak. it kinda resembles diatoms but it is acting a bit different.....it covers the walls of the tank, the sand, and the rocks. it is brown in color and resembles diatoms. im doing frequent water changes, but no results yet. i turned the lights out for 2 days and the algea appeared to be gone....then after the lights were on for a few hours it came back and covered everything!!! im not really sure what to do, but im not gonna get my next mantis until the algea clears up.
if anyone has adivice on the mystery algea just let me know
ps: im only using ro water and i havnt been feedig the tank
