ZEO can be used on tanks of virtually any size if the dosage is right. just keep researching . i have found nano hang on reactors.

I'm about 5 weeks in to zeo. I'm doing it for the colors. I started out with coral snow and coral vitalizer and couldn't believe the difference. Prior to this I was using the ultralith system but the use of those two zeo products lured me to the dark side :wink:

Previously using faunamarin I had issues with brown wafer algae, it took almost 5 months but I do believe that the faunamarin system beat it. Now if I could just do something about the little majano farm I have in the back forty :razz:

I agree with Tony, give it 6 months, then weigh the pros and cons. Thats pretty much what I'm doing. In 6 months I'll reasses if I'm interested in continuing with the whole system or just going back to the coral snow and vitalizer.

Seen zeo done on small tanks as well as big ones. :)

As for all the work, I've just printed out a monthly calendar of what I need to do. Posted by the sump, it should take me 2 minutes every morning to add my stuff, shake the rocks and tick off the sheet. Not too terrible. Let's see if I can actually do it. hehe....

i did the same. thanks to excel i can log all the results good or bad and make changes , aswell as print of dosing charts that i check off as it gets done

To make a long story short:
65 Gal tank, Tek T5x6 bulbs light, Deltec skimmer, lots of flow with Tunze pumps.
Before ZEO.
Healthy tank 1.5 year old, no algae, very good colors and growth.
.
Got Zeo system going, followed instructions to the "T". I did have a small flow mishap (Increased the flow through zeo rocks) Lost 60% of SPS in 4 days.
After ZEO.
Tank full of hair algae and dead corals.

Present time.

Now, recovering slowly, fighting algae battle, SPS getting colors back growth rate never changed really.
Hope this can make some one to think twice before starting ZEO on established tank. May be new tank is OK but did not work for me.

I wonder if faunamarin would do in my corraline algae, it would be worth waiting 5 months if it did :lol:

haha, I'm not sure, that would be interesting if it did though. Come to think of it I don't have a speck of coralline algae on anything except for the rocks.

well I guesI will hold off for awhile since I bought another 250 with lumenarc and a electronic ballast. HMMMMMMMMMM lighting and a new reactor coming will the madness every stop.
