Algae Killer- Blagdon barley extract

I dont have an algae problems in the few tanks i have. Thats because i have UV sterilizer in all of them. lol, but seriously the cost of running those high wattage UV bulbs is not cheap not to mention they need to be replaced at the cost of $100 and up per bulb after one year of use.

If you are talking about ponds, installing UV is a major cost. If your Algae problems is not too serious, i would recommend adding anti algae solutions to your pond. Chemical type is not recommended for the well being of your fish and any kids that might touch the water. i have been using this barley extract based solutions to control algae on my pond and it works quite well.  available from polyart in clementi.
