optimus prime Posted November 25, 2002 Share Posted November 25, 2002 hi gangs, as we know that sands comes in diff size grain, is there any diff. between the diff size to the water quality.thanks! Quote Link to comment Share on other sites More sharing options...
Achilles Tang Posted November 25, 2002 Share Posted November 25, 2002 With reference to a DSB... YES! Big sand grains trap detritus easier. Smaller sand grains don't. Sand-sifting creatures find it more painful to move around bigger grains as they tend to have sharper edges ... SERIOUS! Smaller sand grains are easier for them to move around comfortably. Big sand grains lets in more oxygen so using this for a DSB means you will probably need more than 10 inches or more to get the same effect with smaller grain sizes. Smaller sand grains in a DSB allows detrinification effects in as little as 4 to 5" minimum. If you can find oolithic (mud like), maybe even 3"!

SRC Member newdamsel Posted December 20, 2002 SRC Member Share Posted December 20, 2002 Hi sinn I did just that.. i dugged up the chips leaving a thin layer behind...and cover it with the new sand... but thing is after that exercise, i realise that my tank bounced back to the havent cycle stage.. alot of worms and copepods die during the digging and in the end i have to start the cycle all over again~!!!

SRC Member Sinn Posted December 20, 2002 SRC Member Share Posted December 20, 2002 the problem is... if the copepods and stuff die it wont hurt me so much but what about my fishes and prawn etc? as u said damsel.. the cycle would start again... i dont think i can put all my sand into my sump... even if i could the sand would be way to deep... would a super deep big sized sand bed work as good? and would the live rock be uncured if i took it out of the water for some time while i do the sand? ( maybe ard 1 hr if i super cheong ) Quote Link to comment Share on other sites More sharing options...
SRC Member Sinn Posted December 20, 2002 SRC Member Share Posted December 20, 2002 but then again i think i could accomodate the sand into the sump in the area where my skimmer is..... any suggestions? thanx Quote Link to comment Share on other sites More sharing options...
SRC Member kelstorm Posted December 21, 2002 SRC Member Share Posted December 21, 2002 and would the live rock be uncured if i took it out of the water for some time while i do the sand? ( maybe ard 1 hr if i super cheong ) they will do just fine.. to be on the safe side, grab some newspapers and wet it with the tank water.. then cover the LR that is outside the tank while u do your stuff.. the moisture is suffice.. unless u are in a aircon room.. which drys up the wet newspaper very fast.

SRC Member Sinn Posted December 24, 2002 SRC Member Share Posted December 24, 2002 sump is connected to main tank .... but the partition where i wanna put the old sand temporarily is supposed to be used for the skimmer... thats y i have to remove it once the new sand is seeded Quote Link to comment Share on other sites More sharing options...
SRC Member kelstorm Posted December 25, 2002 SRC Member Share Posted December 25, 2002 seeding the sand is done the moment u dump a handful of old sand into the new sand.. and let the bacteria start to grow in there Quote Let us work together to preserve the world for our children to inherit by being responsible to our surroundings.
