ive been doing weekly water changes of about 3 gallons everytime i have that small refugium and the cheato is growing like a weed was thinking of puting some on a rock with fishing line and placing it on sand in display. i will get the snails and when i put them in the tank i will place them on the hair algea area

and do that once in a while. is it true that see hare will let out a black liquid like a swuid or am i mistaking it for something else? and is there an easy way to make a gfo reactor diy cheap?
