Just follow the routine, 20-30ppm of CO2
Prune and trim off any algae you see, then do the water change.
Add the nutrients back.
Add nutrients 2x more during the week.

Repeat water change and pruning.

Alage can only grow so much in a week, if you keep after them, they
will give up(except for small algae like Green water/BGA etc, these
can be beaten other ways though)

Typically 3 weeks is the maximum time I've ever had an algae hang
around by doing this method.

Adding amano shrimps really help but you need 50-100 to do the job on
a 75Gal.

But if you buy 50-100, you should get them at 1$ ea or less.

Just go in there each weekend for a couple of weeks and attack the
hell out of the algae. Go crazy with the pruning that no algae is left
on anything.
Buy some cheapy plants if you need to after a large pruning.
Remove them later.

Be agressive with your manual removal methods. It's very effective.
Bleach any wood/rocks, equipment etc, clean filter, up the CO2 etc.
Use all of these methods together.

Tom,
I hardly ever post. But I couldn't help it this time. My tank specs
I almost like yours except I have 300W. I have been trying for 8
months or so to have no ALGEA! Im still trying to figure out nutrients
though. I have always been a beliver in adding plenty of nutrients.
Currently I use the whole line of Seachem plant ferts(liquid and root
tabs)I use double what the bottle says. From what I read you seem to
use a little more. The algeas I have now are by no means out of
control but Idont like any. One algea is a dark brown-red on sword
leaves. And a light colored green fuzz. Do you think that I should
increase nutrients? I dont have a PH controller yet but I leave the
Co2 on all the time and the co2 stays between 15-20ppm.I do water
changes about every 1-2 weeks at about 50% Any info would be great.

My routine for a 75 gal with high light, 330w.
50% weekly water change
Prune, scrub, trim, clean FIRST! Then do the water change.
Dose the nutrients back in afterwards.

Add: 1/2 teaspoon of KNO3 for NO3.
1/8th-1/16th teaspoon of KH2PO4 for PO4
1/2Teaspoon of K2SO4 for K+.
15mls trace, for ll the traces.

Add KNO3/KH2PO4.Traces 3X a week at these dosages.

50% weekly water change and repeat.

Consider Rosey barbs, cherry bards, SAE's, Amano shrimps in mass.

Check your CO2 to be certain that you have 20-30ppm the ENTIRE time
the lights are on, so check pH 2x, once in the AM and once before the
lights go off.

Do this for 3 week
You tell me what you think.
