http://zeovit.com/forums/showthread.php?t=10354 is a godsend for those who have not seen it.Aged Salt said:ZEOvit phases depend on the nutrient level & coral appearance. Nutrients are relatively high[with "pooled-reserves"] & corals are dull in coloration. Polyp-extension may or may not be present.
Consider phase 1 the initiatation of ZEOvit method. The basic 4 are used to reduce nutrients in a balanced manner. As nutrients & "reserves" are depleted, the corals become brighter, lighter in appearance & the quantities of the zeo's dosed becomes less.
Enter phase 2[~3-6mos], the corals continue to colorize more & nutrients are becoming more exhausted. During this phase, however, if dosing is stopped for more than a few days, nutrients again begin to rise, & corals become darker. This is due to "pooled-reserves" still remaining available.
Phase 3[5-10months] is characterized by stable nutrients & color appearance of the corals, ie. if the zeo's are not dosed for many days, the N03's/P04's do not increase & coral colors remain fast. In this phase, the stored nutrients are exhausted, as evidenced by the low quantites of Bak/Food7/Start used, with coral color intensive
how many litres is your tank?Im not far away from lowering my doses as well ,
Atm im using 2 L of zeolites , 8 drops ZeoBak every three days , 1ml Zeostart night and morning ,
I also have Zeofood and some sponge food from Brightwell , Overdose that stuff and you get a good crop of algae for a week or two ;)
I started off with carbon , But im not using it atm
Cheers for the tips you mentioned. I will keep them in mind.how many litres is your tank?
IME one of the critical factors in running zeo is the actual zeolites, inclusing qty, flow rate etc. This is the best way to get success. You will also achieve better reults in changing the zeolites every 8 weeks not 10-12 weeks as mentioned by slin1977 and carbon every 3-4 weeks. If your flow rate thru the rx is too slow the system runs ineffeient and if too much you will get STN base up as it strips too much.
my tank is 500L total volume but i run 1.4L of zeolites with 600LPH flow thru it to maintain zerop nutrients i dose 0.1ml x 2 start3 daily only now.
