okay so i have a question i need help with this tank yes i believe i did somethings wrong like i added coral to the tank like a week or month after the tank cycle and then I added fish after that so yes i was moving to fast but im understand that im ready to make it better any suggestions i got a lot of algae on my rock to point it do make me want to give up on the tank and start over and yes i had a idea on what i want it for the tank but i dont have a lot of options in my area so where do i go from here. Its a 20 gallon i have 4 fish and pistol shrimp and a peppermint shrimp and like 12 coral i want to remove the algae off the rock manually by taking it out the tank and scrubbing it but what do i use or how do i do it and overall any suggestions to keep nitrates low do I need to remove some fish and my light run 9 to 9 i have the aqua knight led aquarum light a029 and im thinking about just removed the sand getting getting rid of the pistol shrimp
