new here

okay well im new to this site but not new to aquariums just saltwater. I cannot find the answer im looking for . I want to know if i use a hang on power filter in a tank with a pair of clowns 5 chromis and 3 yellow tail damsels if my tank will be okay.. i know most people recommend you get a protein skimmer and all that stuff becuase most people are stuck on what they hear but i've read a tank with live rock FOWLR andgood water circulation can suvive and do well with just a power filter thats large enough to take all small particles out of the water. If i do 25% water changes weekly and eventully upgrade to a octopus HOB protein skimmer will my tank do ok. for a few months i knwo i have to let the tank cycle for 4-6 weeks before i add any fish

I don't really know anything about saltwater setups but plenty of people here do. I just wanted to welcome you to the forum

If you don't stand up for something you'll fall for anything...

same here,just want to welcome you.
i'm sure someone saltie will be along soon.

when you set up a new tank,hide an extra
sponge or two behind some decor,that way you have
something seeded for you next filter.

The answer is... kind of.

In saltwater tanks you do not want a biofilter of any type. Biological filters introduce Nitrate into the aquarium, which we need to keep extremely low. As a result, adding a biological filter to a marine aquarium with sufficient live rock will not improve water quality, it will degrade water quality.

The live rock will serve as all the biological filtration that is necessary for a marine aquarium. You fail to mention the tank size, but given the bioload you have named I hope you have at least a 29 gallon tank. These fish should fit comfortably into this setup, and with 20 - 30 pounds of live rock you will be in good shape.

If this were my tank, i would use the HOB filter for water movement and activated carbon use only. The activated carbon will help to remove organic waste, similar to a protein skimmer, although not nearly as effective. Given the fish you have selected, this setup should be fine. If you have any desire to keep fish selections outside of the Damselfish family, then the addition of a protein skimmer needs to be considered a necesity, not a luxury.

as already asked, what size tank will this be?

enough quality, pourus live rock, flow, and water changes should be plenty to keep this tank running smoothly.

and welcome to the forum.

Again, it is important that you understand what you are trying to accomplish. In the saltwater hobby you can't just do what you are told to do. You have to understand WHY you are doing the things you are doing. Adding rubble or bioballs inside the filter increases biological filtration, which leads to Nitrates.

So, are you trying to introduce Nitrates into your aquarium?

well actually it will onyl increse it a small protion most of the nitrates come from the bio load of the fish how much you feed them and how well you do you tank maintenance... a 15-25% water change weekly will lower my nitrates along with regular feeding times which will not rpoduce alot of a bio load plus a clean up crew which some of them sift threw the sand finding any other debris. so i dont see how i will increse my nitrates to the point where i will harm my fish. what do you recommened for filtration in the power filter remeber it also has an oxy skimmer which works about the same as a protein skimmer and a filter which is bigger than the tank needs will collect and excess large which the oxy skimmer collects small debris
