    I would like to share this with everyone. In May when i was at the coast i filled a 50ltr bucket with sea sand to use for my new DSB's i was planning. Last week i installed the two tanks, added NSW, washed the sand with RO water and filled the DSB's. The next day i tested the water, the system was not yet connected to my DT, i was stunned to see all the critters in the sump, they look like pods or sealice, about 5-8mm in size. How can this be after 4 months.

    Tagging along. I was in Ramsagte during Aug and thought it was a waste to bring sand back with me.

    hey mandarin,

    did u collect the sand at the breaker point on the beach ? i don't think that sand would be good for your DSB as its bigger pieces of sand and will prompt nitrate/phosphate spikes ... hence the guys use Reggies play sand ...

    your better bet is to go a bit past the breaker, the sand is much smoother similar to the Reggies brand.

    Beach louse. Some are scavengers, others carnivores. This looks like the latter but difficult to be sure.

    This sand i collected at Ballito, not near any swimming area or stormwater outlets and it was low tide at that time. This is fine sand, similar to Reggies. I've done the connection last night and if these critters end up in the DT i don't think they stand a chance, my fish will be waiting. :)
