sea grass lagoon

[Black71gp]

I am buliding a new seagrass/ macro algea lagoon sump on my system.. will be like 10x4x30" or so.. might go 14x4x30 we will see.. what i was wondering is.... would homedepot sand be ok to use for the sea grasses? i plan on like an 8" bed across 3/4 of the lagoon and the last little part would be the equipment area.. i was goign to just get the sand a lot of people are using for there remote dsb and maybe get some nice olotic sand for the top inch or two... what do you think? would tha tbe ok???

The playsand they sell at HD is fine for a sand bed. I would skip the oolitic sand.

how deep should i go? is 8" ok or maybe 10"?? having a problem with hi nitrates in my system now..

6 inch would be enough for the most demanding common seagrasses, Thallasia. Halodule and Halophila will both do okay in 2-3 inches.

I have also been reading about the rdsb... i have a BB tank now and hi nitrates are a problem most likley because of my HUGE bio load.. will probaly go with 8" just to be safe... maybe 10" gotta go do som reasearch on the RDSB as well....
