How do you keep the algae growth at bay with high nutrients in the water?
Not good. You will have problems with too much iodine!

All good advice from @saltyfilmfolks, per usual
What are you seeing happen to your frags? They definitely prefer nutrients in the water, but I haven't lost frags to low nutrients. They usually just don't grow.
Do you have fish in the tank? How many polyps, on average, do the zoa frags have? It takes longer for smaller frags to grow. At least that has been my experience.
Dose an iodine supplement. I use Kent's Lugols solution. My zoa's have grown like weeds since.
How is the water flow around them?
No nutrients needed in my tank!
I've had my tank very healthy with undetectable nutrients for years and years.
There must be something else happening.
Perhaps the tank is too young or something like that.
"Dirty water" is a myth, my friends!

less water changes = more nitratesWell, I have been trying 1 month so far and have gone through 5 frags. Weekly water changes, leds are on for around 6 hours
You could set up an algae scrubber. Instead of no algae just have it grow where you dont see it!How do you keep the algae growth at bay with high nutrients in the water?
change your weekly water changes to bi weekly or once a month.How can I safely raise nitrates without causing a spike?
Yes a pair of clowns, but they are harmless they are afraid of everything. and the frags are always so small!!! about 1-3 heads!!!
Per my post above......................Let your tank mature a bit and try after 3-4 months.

My zoa frags grew at a stubbornly slow pace for about two years in my 75g with T5 lights. I tried a bunch of different combos with ATI bulbs. 6 months ago I made the switch to SB Reefbrite LED's, and the zoas, along with the other corals, have exploded growth. All other parameters I kept the same, purposely, to see if lighting change can make the difference.
I have a kessil a80, but if I were to switch my lighting what would be the best choices?
