are you using fertilizer?
are you culturing rotifers close by, if contaminated with rotifers they will eat as fast as it grows.
light for 16 hrs a day?

no rotifers giving f2
light 16hrs

what kind of light?

i think its a led it's the kit from mamroo200

I think they are flourescent, which should work fine.
What about temp., and you have an air line running like a slow boil.
How much f2?

temp is about 72 74
airstone to a slow boil
this is my first batch
3ml f2 for about 3 gallons

I would split it and put a little more f2 this time, an extra ml, are you using tap water or RO?
I used filtered water ( just after the carbon block of my RODI unit), salinity 1.019, don't use RODI

iam using RO water so i should be using tap water, what about all the crap in tap water

do you put yours in the fridge

I was told not to use an air stone only a hard tube open ended at the bottom of the bottle, also I use a 6500 k compact bulb.
I'm new to this so we'll see how it goes. :neutral:

RO water is too pure, I used carbon filtered water and yes no air stone just a piece of rigid tubing.
the light should be ok if it came in mamroo's kit, he grows nice green phyto.
6500k cfl works good.
what phyto you growing?

phyto
 

most likely it has to brew for a longer period of time.what strain of phyto are you using?i use r/o water at 1.025 salinity run through an uv sterilizer.for a gallon of phyto i use about 3 ml of micro algae grow.lighting i made my own led strips using 1 watt leds(25 per strip)various cultures like different lights(nanochloropus-white/red,tetraselmus-red,isocrysis-blue-etc)i'm using aquamedic reactors for my cultures and rotifers
