Hello,
Génial le projet ! Un type qui a réalisé une installation telle que tu la souhaites la présente ici:
http://www.thereefuge.com.au/board/threads/tidal-mudflat-aquarium-mudskippers.1744/Le type en question parvient à reproduire
Periophthalmus argentilineatus dans ce bac (ce qui est une première documentée !).
A la page 7, il explique le système de marées. C'est hyper simple. (Attention, il y a un schéma à la page 7 qui n'a rien à voir avec le bac présenté):
"all water filtration is undertaken within the sump. Water passes from the tank, into a 200micron filter-sock. Within the sump, there is a small sponge filter that aids in biological filtration and as particles are removed before they reach the sump (via the filter-sock), this sponge filter rarely needs changing. A heater is also contained in the sump and maintains the temp at 26 degrees. During the low tide cycle, there is no flow/filtration in the main tank (although filtration is occuring in the sump where the water is stored). During the tide change, water is pumped from the sump at a rate of 2000L/H and this flow is maintained for 6h (replicated the vast water-movement that occurs over a mudflat). The 6 hours are up, the pump turns off and water drains back into the sump to the low tide level for 6 hours. Tides are staggered by 1h each day to ensure that the cycles change slightly each day (is the reverse of what happens in nature where tides move forward 1 h each day)."
Tiens-nous au courant de l'évolution de ton projet !
