southdown sand

[jerrybsal]

I have a 125 FO tank that has been running for 6 years.I have about 3" of Caribsea sand above a plenum.I want to make the sand bed deeper, could i just mix in a few more inches of Southdown sand or will it harm the fish or sand bed. Or can I only mix in the same sand?Thanks for any help....

It will be fine. Just wet the sand before you add it and add slowly so you don't cloud the water to bad. I read somewhere else where you can use a large diameter pvc pipe from HD or Lowe's to direct the sand where you want it in the tank. Just pour it in the end out of water and point the other end where you want it to go. Hope it helps.
