Is my tank doomed?

Well-here's the scenario-60 gal stocked with tetras,corys,mollys,bumble bee gobys. Swords, alot of swords. I have a Crapo-plus (because I did'nt know any better) Brown algae is starting.Wife says fish are struggling for air-Co2 is at 3.0 ( with carbo-plus turned up to 5 leds,only run in daytime) Kh-5,Ph-7.6,temp-79, Dosing iron,potassium. If I turn up Co2 full blast I might get 15-30 I don't know? Carbo plus won't hurt fish right?

3ppm co2 ? I would definatly try to get the co2 up higher

get rid of the bumblebee gobies and get a pleco.

I have never had an oxygen problem so Im not sure about the fish gasping, and I know nothing of carboplus either, so im not sure it will hurt your fish, but I kind of doubt it

What causes fish problems is low oxygen. If your plants are not producing O2 then you need to get an air pump.

Brown algae is pretty common.

BTW if your CO2 is 3 ppm then the Carbo Plus is not doing a thing for you. Normal water should have a CO2 level in the same range. The bubbles that come off the unit are NOT CO2 but Hydrogen.

Swords aren't the fastest growers really. You might want to look at water chemistry as well because a lot of cycle conditions will damage fish gills causing them to look like they are gasping. You said brown algae which is something that afflicts new tanks and would indicate yours might be cycling. You might want to also make sure you have sufficient lighting as well.
