Hi all
I have a 100lt/20gal AIO tank. It is 1.5 years old. I have two clownfish and a few corals. I run a Redsea ato (worst purchase ever) and I have a Redsea 4head dose.
I cannot get my phosphate or nitrate above 0.01-0.02 doing weekly 10% water changes. So I have this ugly brown algae, that I have read lives in very low nutrition numbers.
So I changed to monthly 25% changes to let these numbers climb,but it’s like resetting the tank every month.
What would you do?

I have had a 500lt / 150g in the past and had none of these issues

I would like to run nitrate at 15-20ppm and phosphate at .02-.04
Any suggestions would be great

How often do you feed your fish? What type of filtration do you have? How long have you had dino's in your tank?

You can actually dose nitrate and phosphate, but I've never done that, so bumping for you for more help. Good luck

Dry rock or live rock?

Try feeding more. I feed 5-6 times a day. Works for some but not me. So I dose ammonia.

For my ugly stage/dino’s I bought a marineland magnum filter from petco. Manually clean/remove algae while canister is running 24-36 hours. While cleaning remove all the large debris with a fish net. The canister filter will catch all the small debris. After a few days of this method all the brown slime algae was gone. I’m still running zero nitrate and .01-.02 phosphate. But ammonia seems to keep everything happy enough so far.

Many ways to get it up but I will say what I do. If phosphate needs to raise i use reef roids a little and it will do some phosphate and nitrate.

If nitrate only needed i use spectracide stump remover it is a potassium nitrate and I mix with RO and dose some.

I feed my fish once a day I watch them and they get enough for that feeding I would feed them more but I find they just don’t eat it. I might have to start dosing I have thought about it but it feels like pouring money into the tank just to remove it in a weekly water change

You could go from weekly to bi weekly water changes to help and increase your feeding. Typically you will see nitrates from frozen foods and phosphate from pellets/flake foods.
