Do you know the GH of your tap water? If it's sufficiently high enough calcium shouldn't be an issue anyway. If your tap water has 0 GH (like mine) I don't think 1 tsp of GH booster sounds like enough to bring your GH up on a 55 gallon. I use about 1 tbsp of pure calcium chloride in my 32g (if I'm dosing the whole tank) and that in combination with the same amount of epsom salts only brings my GH up to 20ppm, still really low. GH should be added back in when you do water changes to bring your tap water to the level you want, it's not like other ferts that get used up and need to be dosed regularly based on how fast your plants go through them. Bicarbonate (KH) is the same thing, you don't want to be adding more and more, you want to keep it stable. Most people now agree that it's not needed for plants, only for certain fish sometimes.
