I am designing a 7000 litre circular cement cool water marine tank in Tasmania intending to populate with local marine species and lots of local seaweed species.
Mininum dimensions 3 metre diameter 1 metre depth
Currently thinking about appropriate lighting to support macro algae.
Also how to place lighting.. above tank, submerged etc
The aquarium will be built on the south side of our 2 story home and 100 feet from the water's edge. It will be in the shade of the house at all times, apart from a few strips of sun during summer.
After construction I will build a conservatory structure over it then finally open the house out to it.
Concept so far is to have a 20,000 litre rainwater poly-tank nearby which will hold natural seawater pumped up from the sea when water quality is best. This will be the source of water for the aquarium.
I currently am considering filtration with a swimming-pool type sand filter which will also act as an aerobic biofilter.
Nitrates dealt with by seriously large and frequent water changes from the holding poly-tank if and when required and a seaweed macroalgae dominant aquarium (ie refugium not required).
Still lots of planning questions in my mind.. I am grateful for any serious feedback on my concept.
I am fairly content so far with the overall concept but always open and grateful for ideas.
Pumps etc will be in an equipment-shed outside.
Lighting is my current concern
Cost is not an issue.
What lights and placement.
Do I dangle lights from the roof or submerge etc... I would love some ideas on alternative concepts .. the less intrusive the lighting the better
I only have experience with LED with my current aquarium
Whatever I use will need to sustain a heavy macroalgae marine tank...
