DIY presents challenges keeping the amount steady. I set up a system that
varies .1 unit through the whole day last week. It was a gas tank set up:)
If you can....get one. It'll be the best thing overall you can do unless you
like lower lighting ideas.

If you lots of flow sometimes you won't see much. I doubt you have much flow
though. Gasping fish tanks have too little at 28ppm. This depends on your
fish tolerances/load/plant growth rates-types etc but most fish have little
issue with it as long as there's some turnover and good
movement/circulation. We won't throw you in "CO2 jail" if you lose some due
to water movement:)

Don't need the tabs but they don't hurt too much either. I'd back off the
trace mixes(liquid water column stuff) for awhile(4-7 days) and see what
happens. Your feeding the algae likely. Work on the other (NO3 and CO2).

Well it needs to higher than 0. Hard to say since we don't know.
Try this though:
Check you tap water's nutrients by asking the water company, PO4, NO3, KH/GH
etc. Do a large water change and assume that it's close to what they say it
is. Add enough KNO3 to raise it up to a decent level(in your case about 1/4
teaspoon should yield about 6ppm I'd guess for your tank). Add a 1/4
teaspoon of K2SO4 or KCL as well. Feed fish well. Wait a week and see what
happens. Keep up on CO2 and water movement.

You don't:)? Come on it's weal fun:)

It's CO2 plainly in your case. I was at this point years ago. Drives folks
bonkers. I've been there and was there for about a year or two. CO2 CO2
CO22. Keep it steady and a good amount in there. Move your water around
some, even the surface a little. Consider a gas tank. It's not that bad and
once you get one you'll be like " Gee, If I had only known it was this easy"
and you almost never have to mess with it. I touch mine once every 2-6
months for maybe a minute tops. Quite a few only get touched when they
bottle changes which are 10-15$ each and occur once a year to once every 5
years. The big part of the plant equation is taken care from then on. Easy
for you and the fish/plants and hard on the algae. Is it worth it?
The gas set ups are not that much money anyway. Reg and valve for 75$ and a
tank for 40-100$ and a reactor some method of adding it to the tank free to
30$ or so. And you can daisy chain off that same system and add another CO2
enriched tank for the cost of a valve and another reactors set up(20-50$).
It gets cheap and easy then. Plants grow and algae doesn't. Many folks that
do have the algae problems have namely no N, P or K or have DIY CO2 with
something not being done right etc with CO2-namely lack of CO2 during their
photoperiod. Excesses are generally caused by lack of plant
growing/assimilating the macro nutrients so they build up instead of going
down. Get a good NO3 kit like the Lamott(45-55$) and a good CO2 set up. Life
will be easier. SeaChem makes a cheaper one that's decent(15$) but I'm still
quite partial to the Lamott. Sorry Greg:)
