Really fan of your ideas about bacteria, Anthony !!!
I would like your advice of start dosing Zeo.
System:
- 180G / 680L total water volume (redsea 750)
- Hybrid light LED and T5, Strong flow, large skimmer, roller filter, Activated Carbon, Calcium reactor
Started all over a year ago, first time with dry rock - actually it is all ceramic - and a few LR to seed, but having nothing but troubles ever since. Been fighting GHA, bryobsis and different kind of turf algeas. I think it turned into a self-fueling machine, but finally it's going the right direction.
All paramters are fine (verified by ICP test) and PO4 and NO3 is almost zero in order to get rid of lots of turf algeas / because of the turf algeas - I'll get back to the nutrient export later.
The plan is to run a primarely sps tank. My former tanks have been mixed reef with more or less success ...
I reasonly got some sps frags (lost the other corals in the battle with algeas), some doing ok and some don't. Actually the agroporas are doing best

Never the less I decided use part of the Zeovit system to increase the vatiaty and diversity of beneficial bacteria so I orderd the below and made a dosing plan based on the guide from Korallenzucht.
Please comment my plan, also if you will suggest other or additional products.
- ZEObak
dose: 1 drop 5 times pr week
- ZEOstart 3
dose: 1 ml pr day
- Coral Vitalizer
dose: 2 drops pr day
- Spongepower
dose: 2 drops pr day
Phosphate and nitrate export, and health of the tank:
For the last six weeks I've been dosing large amount phyto daily, slowly ramping up the amount of phyto.
One hour before lights out the returpump stops for 2 hours, while I dose the phyto to the tank.
The phyto consume most of the Phosphate and nitrate, which starve the algeas and feed the copepods and rotifiers.
Most of the phyto are removed the skimmer, and the PO4 and NO3 is almost undetectable, even I feed the fish a lot.
I also add copepods once a week and rotifies around 3 times a week.
This phyto strategy is inspired by Dana Riddle and
@skimjim and seems to work very fine.
The algeas are disappearing - slowly but steady, keeps my fish fat and healthy, and support all kind of cods, critters etc.
I will not decribe it as a ULNS since a lot of nutrients are added, even the PO4 and NO3 is close to zero.
I think by adding phyto- and zooplankton and bacteria (a lot of nutrients) the tank will be very healthy in a natural way, thereby having the ability to host healthy corals and fish.
