UVS destroys algae: by products?

[StanChung]

hi all,

if using a UVS destroys diatoms and green water, what are the by products can we expect? not an easy question but maybe somebody may have read it somewhere...

It still has been disputed. "hear-say" that UVS will destroys Fe and some other T.E

UVs most probably did not destroy the TEs, but causes them to bind either together or to something, thus rendering them inactive to be used as fertilizers or trace elements to be used by the plants...

Stan, I would say, after the algae are destroyed, they came out the UV as dead cells and will start to rot... i.e. they are converted to potential ammonia, nitrite and nitrate producers! It would be good if regular water changes are made with the use of UVs...

hi guys,

sounds logical...more food into the chain...
