As expected it does not take too long to get results from this stuff
Ok looks like we have two reviews in one here so will break them down seperate so not to confuse.
First the Ultra Clam - You are doing everything right, and the colouration you are seeing is not your imagination. Some mixing advise obtained from the big Clam keepers over the boarder, they mix the goo up, leave for 24 hours and then mix the surface residue back in, this makes a stronger mix and also gives even better results, so if you have been dont drain this off, just mix back in. You can make up sausage like amounts and freeze into feeding portions and defrost on use. I would stick to the amount you are feeding for now and just keep a close eye. You will know if you are over feeding as your nutrients will rise. As for the filter sock, if possible divert for 2 hours after feeding, if not, I am sure it will not have much of a negative effect.
Now the MinS - MinS is the first nutrient building block for the ultra Lith System, (Faunas Low nutrient system). As it is a strong amino supplement any tank fed with this will see big differences in polyp extension and also growth, colouration also to a degree, although the Ultra Amin and power traces provide higher colouration. Things to note when using MinS on its own is just nutrient levels, as you have not increased your bacterial activity to cater for this big positive shock, so again watch the levels and keep in mind you already are putting MinS in the system with the Ultra Clam.
Photos welcome.
