New tank set help plz

[Freshermenreefer]

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

First of all, welcome!

You didn't necessarily do anything wrong. I may have not added 4 fish to a 20 g all at once, but it's manageable. That algae is just part of tank maturing and something you're going to have go through for a while.

To manage a small tank...do water changes to manage your nitrates - not sure what that will look like, but a first I'd go with at least 10-15% per week (maybe 25% or a 5 gallon bucket worth), you'll have to test and manage that appropriately. Manually remove algae (suck up with hose). Don't try for pristine, just get the worst of it. Be patient, and no more fish.

You didn't mention test readings or filtration (looks like HOB). Those would help us with advice.

What is that pillar thing made out of? It's hard to guess what kind of corals are on top of it but I would say that none of them need that much light.
Algae--take the rocks out of the tank if you can and give them a good scrub with a toothbrush or something like that. If you want it very clean you can lightly spray some hydrogen peroxide on the rocks then scrub, but that will definitely slow down the natural maturing process.

also, in both your threads you're giving very little information that could help others help you. if you don't have test kits at least take a water sample to a fish store and get them to test it for you.

Its like a frag thing i get its reef safe i was thinking that about the light to i will move it I'm just waiting on my frag rack so that was just temporary and that's the thing I don't test because I used to have a test kit before i left the hobby before but that's what I was saying the closest to pet stores by me do not test water I don't have a lot of options is that any peroxide I can use like the one I got at home
