i just had my water tested. I've added cured live rock its been cycling now for a week. went to a privately owned store near my house- they have great google reviews. The owner has been incredibly helpful and has tested the water for me. said i could think about adding fish in a week or so but my nitrate levels were a little high still- 7.6. i want to learn how to do all of this myself. how do i read the hydrometer? i put one in myself and its not getting the same reading hers was. my hydrometer is off the charts and hers read in the green. not going to lie i just opened the package and plopped it on in- which now in after thought probably wasn't the best thing to do. any knowledge would be helpful thanks!
