What else can I do?

What kind of bulbs do you have?

In my digging, I discovered that Cree cool white LEDs cover the spectrum that cyano thrives in. I had my cano problem mostly under control, and then I switched out my t5s (2-Blue+, 1-Coral+, and 1-Purple+) for LEDs (Sol Blues). The cyano exploded over the course of a few hours, and I can only assume it was the spectrum provided by the cool white LEDs that did it.

I have t5s
2x ati 12000k
2x ati 20000k
1x ati 420 actinic
1x kZ Fiji purple

I just put them in 4 days ago in an attempt to get rid of the algae problem. The previous bulbs were over a year old.

I don't think any of those bulbs should be an issue. It is the shorter wavelengths that cyano likes.

Oh. Here's a FW planted tank article on cyano that isn't as dry as the previous one.

Ha thanks, I tried reading the last one and didn't make it very far.

So being gram negative you think chemiclean will help kill Dino's?

Enigma · #6 10-17-2012, 02:38 AM

If dinos are gram negatve then Chemiclean should kill it (unless it is resistant . . . Which bacteria can become). Chemiclean only kills gram negative bacteria. Gram positive bacteria (like your tank's biofilter) are unaffected by it.

The suggestion that dinos are gram negative seemed to be little more than an educated guess. Since you saw a reaction from whatever it is that you've got growing in there, I would guess it is gram negative: whether it be cyano or dinos.

I personally would try it again, providing the kivestock handled it well, but I'd give it a little bit of time or do a couple more big water changes before doing so.

Dinos are a cyst,not a bacterium.

I dosed chemiclean twice in 48 hours on my small tank last year with no I'll effects. Just be prepared for lots of water changes. I have no idea what type of algae you are battling so can not say whether this will work. Have you tried a blackout?
