I have a 75 gallon tank with one oscar in it. I run a fluval 406 and an aqueon 75/90. Im looking at either getting rid of the aqueon 75 or replacing it with a second canister filter. Im trying to get an idea what my ideal filtration should like 2x 5x tank volume.

Welcome to our little community.

I don't think we need to get too complicated at all. I would probably suggest that another 406 would give you more than enough filtration if you only have the one Oscar at the 75 gallon. Have you actually kept an eye on the water conditions, have you been having problems? If your ammonia, nitrite are always zero that the filtration is doing a good job. Not really any need to spend money if you don't need to

I may not always be right, but I am always the BOSS :-)

Hello and welcome aboard. If you really want to ditch the Aqueon, replace with an Aquaclear 110. Your canister will continue to cover bio filtration, the Aquaclear will offer superior mechanical assistance.

I check the water before my two weekly 30% water changes. Levels are always good. 0 ammonia 0 nitrites 40 nitrates. I'm just at the point where the aqueon looks bad to me. Want to remove it or replace it with something that dosent look so crappy. I have thought about adding a second 406 or a aquaclear 110.

People talk about chemical vs biological filtration. I feel like im in over my head on what the difference is and how to load the trays the fluval 406. The 406 is only a few months. It is still running the stock set up.

Bio filtration in a canister is the ceramic rings. Your beneficial bacteria lives and grows here. Chemical is generally a carbon bag or some variant of. Your 406 should have as much ceramics as the trays will hold. Remove any carbon and dont use, it will harm fish with continuous use. Your water changes need to be of more volume. 40 nitrate is too high. General rule of thumb is when nitrate hits 20, its time for a big water change. With a pre change level of 40, you need a 50% change just to get to 20. Do 75% changes every 4-5 days, water will be much healthier for your fish. Should you add an Aquaclear, set it up with the stock sponge on bottom and as much ceramics as the media bag will hold. Bag will hold more than they give you. And again, do not use the carbon bag.

Thank you for advice. I always though 40 was the threshold for being to high. I will defenitly started doing larger water changes. I will just pick up an aquaclear 110 and trash the aqueon. What should i be putting in the trays in the 406?

Your 406 trays should have as much ceramics as they will hold. Being a Fluval filter, I presume it came with Fluval Biomax ceramics. All my filters, canisters and hobs have as much of this brand as they hold. Its a high quality bio media, should be available most everywhere. You will need to pick up a box to fill the AC 110, and maybe your 406 will hold more than you currently have. You absolutely cannot provide too much clean water for your Oscar. Drive those nitrates as low as you can manage, and you will see a very noticeable difference in your Oscars general health. I run 11 large tanks with various South and Central American cichlids. Nitrate rarely exceeds 10ppm on any tank,some barely register anything. I chew through about 1500 gals of water every week. Yes, my water bill is up there(way up there!), but fish are happy and healthy.

Looking for a good canister filter for a 65g. One not too huge but good gph, and easy to service/change media.
