After using the Zeovit system for about 6 months, I believe that the system works if we practise it according to the guidelines and methods and not kehkiang and do it our own way. Like Roidan mentioned, its a relatively new method of
The dosages are more or less standard and will gradually taper off especially the Zeostart. Overdose it and bad things like tip recession will happen with the SPS and it will signal that your tank have entered a new phase and the dosages have to be lowered. It means that you have to observe and understand the SPS in your collections and identity a 'canary' for the adjustment of dosages. There is a new version of zeostart called 'zeostart2' which wil greatly reduce the ill-effects of overdosing.
The system is relatively simple once you get the hang of it but its not a system for the impatient, it takes time to fully unlease its potential and we just need to stay the course to observe the effects.
IMHO, For reeftanks that are already super beautiful and healthy with undetectable NO3 and PO4 aka a well-tuned stock car, I think that running zeovit on these tanks will bring out even brighter colors and better growth because it will further drive down the nutrients to even lower levels that currently afforded by other more conventional means like Rowaphos etc etc. This is akin to fixing better electricals to a car or putting in a super-charger to give the stock car an extra boost.
My tank pic about 1-2 months ago I think.. its much much better than 3 months ago before dat. For me, it works well enuff to constantly improve my growth and colors of the corals. The colors cannot beat the guru's in the forum but its the best I have seen in my tank so far. Just imagine what it can do to your already fabulous tanks?
