I have a 125gal with a 55gal sump/fuge that I am using the miracle mud/grape caulpera ( I also have a ls with rubble lr section that I will have cheato in when I finally find some
) The cycle was fairly quick, only 10 days to go from Amm. >5 to Trates < 10. So far I have had no issues with trates or algae blooms but then again I just started stocking with fish (4 Firefish) because I was spending all my money on lights, skimmer and other equipment. After the cycle was over I tossed in some Astraea's and Nass snails, added a few scarlet/Hawaiian/blue legged hermits and 2 medium sized emerald crabs. I do 10-15gal water changes every week and so far have never had any Trates register on my tests.
Now as far as recommending it...well I think that it is something that you have to decide on your own. If you search around the different boards on user experience with it you will find a lot of people who have never used it saying it is crap, you'll find some that have used it but have claimed that 'it' caused an algae bloom (some people like to point fingers everywhere but in the mirror), then you have some that are happy with using it but for some reason don't really say much about it. Like everything in this hobby there is pros and cons to using things. I am using it because I plan on having a heavily stocked reef and think that the added trace elements will help the corals. Take a look at what your plans are for your tank, do some research on the stuff you want to keep, do more research and then make a choice.
Hope this helps you some and maybe some people that have actually used it longer than me ( approx 3 months ) and not just a bunch of naysayers with no basis for spewing a bunch of hearsay reply.
