siphon??? use a hose to do it. u can either buy a handheld hand-pumped hose for ard $5 or use a normal rubber hose.
aStRo: Got it.
place ur rowa in either the first or last compartment (in the water, not btw floss) will do relatively ok but IME not as 1/2 as efficient when coupled wif a FR. 4 spoonful is ok or not, i do not know as i do not know ur tank size.
aStRo: first compartment? wont wad debritus flow down from my main tank be collected at the nylon bag? My tank is ard 2x1x1.
IMHO, a general guide will be to calculate the true water vol of ur setup and use the recommended dosage. add in 30% of the rowa, then 10 to 20% increment thereafter every few days till u reach the recommended dosage.
aStRo: got it. Thanks bro.
