It seems as if P. hepatus is now happy and feels safe. For the first time she is swimming around with the other fish. Cool!
I have been running the RO unit since two days ago trying to make enough RO water for a 60l water change. This is taking forever!
I bought some Nori from Woolies and attached it with the SeaVeggies clamp. After about 10 minutes the Purple Tang started nipping at it - and now every now and again it eats some. The Yellow Tang does not look as much interested, however it did eat a couple of pieces that came off.
I woke up only to discover my one small percula is gone... No body, no trace... I guess the boxer shrimp got hungry ☹
I went to Sterlig Aquarium in Ontdekkers Road in Roodepoort and purchased:
It seems the alkalinity is slowly rising. It is now at 6.0 and the calcium is dropping - at 515.
Went to Exotic, and what did I do? I purchased some fish... Since the Ammonia/Nitrite levels were doing fine I assumed it would be fine to add some small fish. So I bought:
When I got back home I saw an explosion of brown algae on the front side of the tank - on the live rock and on the substrate. I guess the white light, daylight, high phosphate levels and dKH buffer additions fueled them.
Since Alkalinity, Calcium and pH all need to be balanced, I bought a Calcium test kit. The Calcium seems to be at 545mg/l! That is very high. Since my Alkalinity is only 7.0 dKH, I decided to make use of Kent Marine’s Pro Buffer dKH. I started adding 35ml to the water daily. I also stopped adding kalkwasser. The idea is that since kalkwasser is a balanced supplement, I first need to get the proportion of Calcium and Alkalinity right then I’ll resume adding kalkwasser. I think the different salt I used as well as the RO water to fix SG messed up the balance.
