The only reason there would be anything wrong with 4 would be a really skewed calcium to magnesium ratio. Ideally, you want about 3-4 to 1. It's really not so easy at all to run up against a deficiency of either. So unless you have some really funny tap water, I wouldn't worry about and and look elsewhere for any problems.

It's mostly about stability and knowing I have enough without testing for it. My 125g is growing excellent right now, so I will continue to add what I've been adding. I'm going keep my tank at a GH of 5 to 6 each week. When I do need to add, I go for about a 3.5:1 ratio of Ca to Mg. It probably isn't necessary, and I'll likely experiment with it in a few months. For now, consistency is the key for me. Want to get past the 6 week stage, which is the toughest in my opinion when starting a new tank. Thanks for the replies!
