Added too many fish at once-Nitrates

I should have known better. I ordered black bar and tiger endlers within the same two weeks. I added 13 endlers--most of which are only a few weeks old to my 10 gallon tank, which already held 2 Norman's Lamp eyes, a Honey Gourami and a GBR. I've been keeping fish for 6 years now, but for some reason, I forgot all about adding fish slowly. I was too excited about my new fish! Now, this morning I took a nitrate reading of that tank, and it was 40. I did a water change 4 days ago. I haven't had a reading that high since I cycled the tank 6 years ago. I know its not TERRIBLY high, but I'm concerned especially for the GBR, as I know they are sensitive. I did a 40% water change after I got the reading, and will check it again in 24 hours.

I have a 20 gallon, but I'm keeping most of the boy endlers in there, and most of the girls and a couple of boys in the 10 gallon. I also don't want to cross the black bars with the tigers, so as you can see, its confusing. A lot haven't even colored up yet so I don't know what sex they are. Otherwise, I'd put some into the 20 gallon, if that would help. I guess I could put some fry in there, but my endlers tend to "bug" newcomers to no end. The black bars pester the tigers, thinking they are females, I suppose. If the nitrates continue to run on the high side, what should I do? I've been scrubbing the media in my filter cartridges with my hands in tank water when I do water changes. This time, since adding the new fish, I noticed the cartridge was a lot dirtier than it normally is. Should I continue this practice? Or only scrub or swish it once a month or so?

10 gallon- 8 Harlequin Rasboras, 1 female betta.

20 gallonH - 1 Peacock Gudgeon, 2 Skunk Cories, 1 Sparkling Gourami. , one male betta, 2 nerite snails.

55 gallon - 3 Turquoise Rainbows, 1 Boesemani Rainbow, 2 Australian Rainbow, 4 Gold Dust mollies, 1 L. Dorsigera, 2 White Cloud Mountain Minnows, 1 Honey Gourami, 3 Cherry barb, 1 Koi Angelfish, 4 female betta.

Hi there, i clean my filter media maybe once a month, when i do this i dont vaccum and such just a bit of a water change. Since you have high nitrates you want the bacteria to begin to increase and constantly scrubbing your media will prevent this. As far as the 10 gallon, it sounds a little overstocked,this could also be the reason for the spike.All you can really do for the nitrates is do frequent water changes and watch parameters. Goodluck!

Thank you, Tetra. I won't touch the cartridge this time, won't vacuum, and will do a small water change.

I checked the nitrates again this morning, and they are 30. So much better than before (and its been 5 days since my last water change) so I'm feeling a little better about this.
