Hi,

It's the first time I use a sand substrate, the Flourite Black Sand. I noticed that it is impossible to vacume it like a gravel and no way to stir the substrate while you vacume it. Is this substrate a source for organics sedimentation and later problems?

Hi Jonny,

Yes, sand substrates need cleaning, in my always humble opinion. :eek:

I use a vacuum with a relatively larger opening and a body with a greater volume. This allows the sand to swirl and settle back down.

I tend to work slowly and do smaller percentage of the tank each time. I use a glass stirrer and a bamboo skewer (something with a little 'flex') to stir the sand and work up next to the edges while hovering the vacuum over the area being stirred.:)

I just squeeze the siphon tube to reduce the suction to reduce any sand from being sucked up.

Thank you both, I'll use the squeeze way, sounds practical. Eventually, I'll put sort of a tap on the tube to definately adapt the flow
