Time for a way overdue update. If I didn't mention it here, I recently purchased a dwarf lionfish for Jr. Three weeks after lionfish introduction, I noticed GHA growing. Haven't checked phos or nitrates due to busy schedule. I'm pretty sure the extra feeding is the main contributor to GHA. In regards with GHA, I noticed that they are only growing on the highflow side across from my gyre. Is this normal? Depending on the phos and nitrate results ths weekend, I might have to purcahse a skimmer. A definite fact though is that I finally have a reason to but a tailspot blenny and lettuce nudi. Will be supplementing with nori once GHA goes away. The tank was doing really good with a skimmer and everything is growing until the extra feeding was included. A clam would also be an option since I got rid of the bumblebee snails during the upgrade. Been reading up on GHA and would like to consider a biological approach first before I go with Chem warfare. Top three params are stable +/- 0.4Alk, 10 Cal and 20 Mag. I still have my doser sitting and collecting dust again due to busy schedule. Unfortunately both my blasto and cristata passed away due to the dragon soul torch. It also stung my OG hammer but is currently recovering. Didn't realized how long indo torch sweepers can get in the middle on the night. Thinking about just placing the torch on a frag rack away from everything else. My black torch on the other hand is much more mellow and doesn't sting my hammers. If I introduce a skimmer, I'm thinking about reducing the light for the chaeto or just have the skimmer run during the day and chaeto at night. A little too early to tell but will consider it once I plan out my gameplan. SPS. All are still alive and some have almost fully encrusted the frag plugs.
