Lots of discussion around reefscapes from walls of rock to the latest craze for minimalistic reefscapes which I am.not a fan of.
Everybody will have their own ideas of what reefscape suits them best but do the suit the fish we are putting in them?
IMO plenty of rock can be used and still have plenty of swimming space. Not just at the front of the reefscape of course but in amongst the reefscape and behind it giving plenty of water movement all round your reefscape. This is most important I find.
When I set up a tank I do so with a good idea of the fish I am going to house in it taking in their requirements. Also, we must remember if we are housing corals that reefscape will change as they grow. Figure in that into you're reefscape design. Access to equipment like powerheads and wave makers need to be considered.
There needs to be plenty of thought into the reefscape you are trying to achieve. What it is not is simply dumping in a load of rock any old how, no wall of almost solid rock. For instance, it was suggested my rock is piled up against the back glass. Nothing could be further from the truth.
Although I do have some rock against the back glass most of the rock isn't at all. There is plenty of space for my single tang, copperband and black leopard wrasse to explore in and around my reefscape. Hangovers caves nooks and crannies as well as open areas are all there.
Water movement is also a consideration. EG I have 2 Tunze 6040 wave makers you will struggle to see on the rear back corners providing plenty of pulsed flow around the back. I also have a Jebao gyre near the waters surface and a Ecotech MP 40 half way down on the side glass. Add to that a Jebao 8000ltr an hour return pump.
We then consider lighting our reefscape but that is for another time and thread really.
All the above that I have achieved is based mainly on experience with over a dozen reef tanks, studying not just my own aquariums but that of others along with diving and snorkeling in the Red sea.
Finally, I try to mimic nature as much as is reasonably possable (you will have to put you're own idea of reasonsble) Mother nature has the answers just ask and follow her teachings again as much as is reasonably possable and you won't go far wrong IME.
