Hi guys. This is my first marine setup. Ive visted a lot as a stalker. Still new and obviously dumb. When i first setup the aquarium i waited 5 days trying to get all levels as close to normal as possible. The rocks i scaled from a guys shed. Been laying there for about a month. The substrate is brand spanking new. After the on my 6th day i started with the Red Sea Reef mature Pro Kit. I followed e erything to the book. Im currently on day 7 of the program. According to the leaflet i was suppose to get algae and diato. Blooms starting from day 4. Still no bloom. My temp is at 24.5 to 25.2, Ph at 8.1, nitrate and nitrite used to be very high but is gradually lowering every day. Salinity is at 1.025 each day. I did my 5% water change with Red Sea Salt. Im suppose to ad my first CUC this coming saterday which is then day 10. But heres my dilemma, can or should i add the CUC if i had no bloom. I feel very uncomfortable putting the little criiters in there when it clearly feels like theyve got nothing to graze on. Im looking at a sand filter starfish as my first cuc or maybe a bristle starfish?
