Substrate Change

Morning all!

 

I'm thinking of changing from fine sand to something a bit heavier. Any advice tip on what (and how)?

 

Cheers!

Hi there

IMO it can Depending on how deep it is, I myself a number of times in the past have taken it all out using a large landing net , which was about 2 to 3 inches deep and just replaced it with new, but if you have a deep sand bed I would take half hour at a time and do a reasonable size water challenge.

Just changed mine from a typical sand to the Red Sea Reef Pink argonite stuff, it looks really good and is a bit bigger grain than sand, so little heavier, i.e. Not blown about as much.

I changed mine from sugar fine sand to 3mm to 5mm argonite and havent looked back. No more blowing through to the glass bottom and it's much easier to clean with a siphon. I removed all my old sand in one go then added the replacement over a couple of weeks.

Be very careful replacing it all in one go especially if you don't clean the sandbed often as you will be removing a lot of beneficial bacteria or worse, releasing large amounts of hydrogen sulphide (tank killer).

True, I should have said that I have a deep sand bed in the sump and my display sand was quite thin and cleaned regularly.

When I changed my sand bed I siphoned the sand out with a i" bore pipe, Takes all the dirt ect out at the same time. Took a few evenings and about 400 liters of fresh salt water to replace the old. But no trouble with the tank. I too went for larger grain sand.

 

Also a good idea to soak your new sand in old tank water for a couple of weeks before adding to the tank.
