I did during the initial cycle but it is now well controlled. I do have more algae than some but I admit I'm bio-overloaded and a compulsive overfeeder. Alot of focus gets put on silicates but remember that the algae needs the nitrates to actually grow and turn the silicates into shell. Keep the nutrient level under control and the minerals won't matter. If I had a sump instead of HOB skimmer and fuge I'm certain my tank would be even better. I don't see why you couldn't have the same results. Also of note, I don't use any water conditioners, literally straight out of the tap into my mix up containers. I'm such a rebel!!!!!
