Has anybody used or know about using barley bales in a filtration system to control string (filament sp?) algae in aquarium housing/breeding shrimps. The system consistes of (10) 55's and (2)75 gal. sumps. Very good water turn over.at roughly three times and hour on most. Some are adjusted to a little less because of the number of newies and fry. The tanks also are used for blue-eyes, nanos, dwarf varieties that do not feed off of the fry and young as a rule. The barley is used to reduce fil. algae and water clarity but does it kill the benificial algae the the shrimp grase on?
Also have a variety of nerites and large snails.
Any advice is welcome. I use it in my pond and works there very well but it only holds koi.
