brown bloom on glass

[earwicker7]

I know that the zeovit guide mentions that overdosing can lead to a diatom-like bloom on the glass and substrate. I'm pretty sure that, for a while, I was overdosing the zeovit, but I'm now at almost as low as you can get--1 drop of zeostart every night and 1 drop of zeobak and zeofood every four days or so. Every time that I dose the zeobak and zeofood, the next day there is a starburst shaped brown bloom on the glass at the point where the current from my main pump (the one from the sump, where the zeo reactor is) hits the glass. There was some tissue loss from a couple of my sps, which is why I lowered the dose (I was using two drops on everything before) but I don't see how I can get much lower than 1 drop on the dosing, which seems pretty moderate for a 50g tank. The bloom has never been on the substrate, and it doesn't get super heavy, but I'm still worried that I'm going to end up causing tissue loss again.

Just curious.. are you dosing any Amino's?

[earwicker7]

Oh yeah--2 drops a day of the regular and the LPS. Is that good or bad?

[earwicker7]

Oops, that's 2 drops of the regular aminos and 2 ml of the LPS.

Hi Earwicker, let's do this for a couple of wks:
1) hold ZeoFood
2)decrease the aminodoses to every other day.

Plz. post up your results in 2 wks. Thnx. Bob

So should I still dose the Zeobak?

[Aged Salt]

Yes, Zeobak is essential. Bob

I have a similiar problem and think it's due to the amino as well. Can you explain why the stopping of the zeofood will help in preventing the algea outbreak?. Also can the zeostart be continued?.

thanks,
Albert

Hi Albert, brownish biofilm accumulates indicate zeo-excess. One can continue all the zeo-components but at reduced dosage. Bob
