When do we use zeofood?
Can it replace sponge power?

If the system runs nutrient poor stabile and if corals tissue has become to get lighter ZeoFood can have a positive impact to coloration. Usually 1 drop / 25 US gallons 2 x weekly works well if you do not have issues with cyanos or other algae.

Alexander I have some issues going on.
I am having burnt tips on some corals for past 1 week.
In last one week only major change is I was letting my nitrate go higher to about 4-5 range. It usually used to run 0-1.
I have been feeding heavy lately.

So Ive been having a lot of cyano... and dinoflagellates, so what I did was stopped ZeoSponge for a month.
My dosing has been:
240gallon
Zeolite 2 lit with 200l/hr, change about 8 weekly.
Zeostart 2 ml/day via dilution spread through the day
Carbon change 1monthly.
My Alk has been rock solid 8- 8.5 for many months: no change
Calcium has been solid stable high at 600..... not sure why its high but its stable at that number for months.
Phos 0-0.001 stable for months.

So my impression is with ULNS, now I increased the nitrate so growth increased and not enough proportional increase in alk. And hence burnt tips, especially on acros that are fast growers.

So today what I did was :
1: Changes the zeolite in 5 weeks
2: increase zeolite flow to 400l/hr
3: changed carbon 1 month today.

Hoping to bring the nitrate down again and have the old balance.

The cyano and dinoflagellates issue is same....

Am I on the right track to fix the burnt tips?

The Ca level and the KH are both relative high, do you have a chance to cross check salinity with a different accurate instrument ?

Replacing the carbon and the zeovit at the same day is not ideal, try to do this on different days or with a week between the exchanges.

Can you post a couple of pictures from the affected corals ? A full tank shot and a picture of your sump would be good also.
