3cm layer of sea sand. Brought back 40L fine sand collected at Rocky bay. Obviously below the low tide and it was full moon. Collected on Saturday. Very fine sand. Left the 40L container in the boot of my car and got my sons to help with the bucket back and forth (14 and 11 years). Cost me a couple of ice-creams.
Hopefully heavier than aragonite and the end to sand storms. 40L water added, actually a water change from existing system.
(and yeah, crap cell phone picture)
Also check the closed cell foam. Got a sheet from a company in south Joburg. Looks a lot better than white polystyrene. It is 19mm thick.
The end result of last nights labour.
Tank is levelled. It got an adjustable bolt in each corner. I closed off the closed loop system. Had a 50mm intake in the middle and two 32mm returns at the back bottom on both sides (mostly now hidden under the sand level). The reason is that the pumps for closed loop is to heavy on power for the flow you get out of them. Also less plumbing.
I did prepare about 220L saltwater last night. The setup before water replacement is 1000L.
My "complicated" current system will be broken down partly.
Marine Aquariums of South Africa - View Single Post - Upgrade my Downgrade
Both displays will be emptied. that is 350 plus 220L. As well as the main sump will be transferred to new system. DSB included. Will keep the remote DSB and cryptic tank.
The quarantine system (you can see the reflection in the glass) will stay as is, would just move out of the living room into the garage (once the garage is sorted).
