No...sand is about 6 or 7 years old....right off the beach...pure Florida Beach sandWhat type of sand are you using. That looks to be playsand and if it is you can use it but its a silica based sand so you will have diatoms and cayno issues for a while it will eventually go away but takes time.
I am already using Leprichon juice, but haven't tried the Unicorn Extract....will have to get some soon.Rainbow Unicorn Extract. Dose 35ml daily for three weeks. 10ml Leprichon juice once only at water changes.
See my ebay store for details.
ahh. its not aragonite crushed coral like live rock or live sand. In florida it should have a higher amount of it(white sand brought to you by coral crushed and eaten by fish, yes its fish poop) but is mostly ground sea shells and silica like most beaches. thats why the juice doesnt work. theres not enough porous places for the nitrifing bacteria to colonize. a refugium & sump w live rock and a vaccume im afraid. then unicorn extract will be most effective. also some of the old tank syndrome (bacterial)additives from DR t and others.No...sand is about 6 or 7 years old....right off the beach...pure Florida Beach sand


Following: my sand bed is doing the exact same thing, and it's driving me crazy!!!! When my lights dim down at night
sand clears up. Tank is 5 years old
good bacterial population
not over feeding
good flow to keep food and poo in suspension to go to
a good skimmer
a refugium or nutrient export plan
a vacuum.

Not sure about my bacterial load, feed once a day, gyre 150 in my 90 gallon,skimmer is rated for 125 gallon water volume,
and another good thread for you.
