Hello forum readers, ok ive now got my two DLSB,s up and running - tech details are as follows two plastic trays 60cm x 42cm by 20cm - filled with special filter sand to a depth of 15cm - took exactly a bag each of 40kg sand - situated at the bottom of my sump box under the return flow from the tank - the sump is outside of the house but in shade and protected from rain - no artificial lighting at all. have "seeded" both trays with .5kg of sand from my fluidiser. spead evenly over each filterbed. as its low tide this sunday afternoon (17.53) im gonna go and collect a couple of kg of sand lifted from the bottom of a pool that does not ever stand dry at anytime - intend to try and skim off the top 50mm or so over the area of the pool, until i have about 10kg and will then spread this over the two trays - hope this will then give a "kickstart" to the life in the trays. anybody have any ideas on checking the viability of DLSB,s?
like a before and after test on my tank water? and any ideas as to how long the system should take to mature? cheers dave nyland
