Hi guys, I'm new to the forum and I hope someone could help me. I have a 16gal fresh tank with few neons, few guppies and 2 swords. Ever since I had the tank set up, water was never pure clear. I had try using different products to clear it up but it all doesn't seem to work.
Also, I notice green algae growing at the bottom of the tank. Could neone help me out??? What are some possible ways that i can fix this problem???

THANKS!!!!!!!!!!
