Purifying System (BLEACH)

[Snaz]

I think bleach is a bit extreme. Your better off with a healthy dose of elbow grease and salt if you want to scrub your equipment clean. As far as introducing algae, that is unavoidable to the spores in the air to LR, you are going to get algae. Remember algae is probably the most common and basic of living organisms and you cannot have water without it!

The real question is how do you limit algae? A suitable CUC, good water and proper feedings will go a long way to keeping algae in check. There are MANY good threads here and all over the net about algae control.
