That is really soft, as is mine, you may want to first monitor your pH for swings and second, consider a buffer of some sort. I pass my water through crushed coral first to increase hardness from 40ppm to 1000ppm or so. This eliminated the violent pH swings. Your pH will fluctuate faster/easier as you increase bio-load as well.
