I have used d-d h2o, tropic, red sea and zeovit. I was not happy with zeovit for the price.
I have been using d-d for the last four buckets with is about one year, and have been happy with it except the last bucket. I think the bucket was not mixed very well. I'm going to have too give IO a try, when this bucket of d-d h2o is done.
I do a daily water change of 1.4G and add 2 tbsp of KH to a 45g mix.
