We noticed that the water was down a few inches again today so we decided to add distilled water because the pH of the tap water we have been adding is higher than the distilled. We hope that by adding distilled water and some new pH down on Wednesday we will be able to get back into the 6-7 pH range because we are still in the 8.5+ range. The plants do not look like they have been growing as much as they had been early on. We believe this is due to the pH being so high therefore when we bring the pH down the plants should start to grow again. We will continue to monitor the pH and water levels so hopefully our plants will grow better than they currently are.
