I used to be REALLY into fish when I was younger, but once I hit HS I switched to larger more emotive pets. I'm currently in university studying to be a marine biologist and suddenly got the itch again. But this time I wanted a marine tank, now that I can not only drive by myself but also have my own finances. This tank started back in January of this year. She fully cycled in 1 month through a mix of patience and some added bacteria. Shes had only 1 ammonia spike, which led to a few zoa losses, and my first pair of clowns passed due to unknown circumstances (I believe bad quarantine from the store, I heard from an employee that they only QT for 1 week). My new clown (different store) is doing well. I've got a new batch of zoas and some GORGEOUS LPS. I'm ADDICTED to color and movement (title *teehee) and am already planning on expanding. I should probably start at the beginning though for anyone who might be interested. Day 1: Jan 22 - Bought used for $200 + $20 (delivery) Week 2: Started the ammonia cycle on day 1 using frozen brine shrimp cubes. Added Fritz zyme 9 on day 14
Hi! I am in a chemistry 3A class and we are doing an investigation on water sample from our local zoo. My group has decided to show the possible differences between two different hydrometers but we need a reference number to compare to. I found an article saying that the standard salinity of aquariums should be 35 PPT. I also need to prove the accuracy (trueness & precision) of the hydrometers. Do I use a refractometer? I am really not sure what to do, help is very much appreciated.
