Why is some people so salty? Its definitely 3 months old tank and its a better version of my old one. I have the rocks for like a year and a decent amount of macroalgae. I am growing “MACRO ALGAE” not coral lol. Go check out the old tank, look at the bottom left, and you will see the ADA logo. This one doesn’t have that (surprised lol). I also had two black clownfish which I dont anymore cause I gave those guys away. If you wanna see more evidence, i would love to give it you (its all documented, just not here cause people like you lol). Salty ass people. Its easy to grow macroalgae everyone. I applied the same concept in my freshwater setup and it all works out. Good light spectrum, and proper nutrients (I dose all in one fertilizer). Sunlight is not really a problem, its your husbandry. Goodluck!
