The new tank being lite with ONLY two 400 watt Metal Halides, and no actinic lighting, people on RC are suggesting 20K (which I was thinking anyways) and using either Radium or XM. Seems more people are saying XM but I think thats just because they are cheaper? I haven't seen Radiums here in town either.

Apparently though, the PFO ballast I am using overdrives bulbs and the Radiums are good because they are good at 430 watts. Which is why people use them with HQI ballasts I guess?

Also people are saying the XM's are certainly bluer. Apparently the Radiums are a more whitish blue while the XM's are a more deep blue.

Anyone have another opinion?

People have been telling me PAR and growth will be fine from either one but for some reason, it worries me. I guess the other upside to 20K is that less algae is likely to grow under them.

Big polyps on acros are called axial polyps.

I need to get back to this thread later in the evening. We have some myths to dispel, :D

^^So why haven't all these myths been dispelled yet???

has to think them up first :)

I am just curious because I went back and read most of the thread and can't really find much that I think may be myth...

I thought maybe some of the cyano stuff recently but couldn't be that since people are simply posting experiences they actually have encountered. Thought maybe my lighting comments but again, it all comes from actual experiences, not just ideas or myths...

C'mon! You have us all wondering! ;)

On another note, I started the Coral Snow today for cyano, so we'll see how that goes.

I am also going to need a 3L reactor according to the ZEOvit.com guys. I PM'd one of the main guys there and he says a 1.5L reactor is just way too undersized for my new Net Water Volume. I mentioned keeping a filter bag of ZEO passively in the sump as well but apparently it won't quite do the same thing. He did say if I can't upgrade it may work but just not nearly as effective.

So I am going to see if I can sell the 1.5L for a decent price and then buy a 3L. If I can't sell it for what I want, then I will try it out and see how it goes.

Right now though, I need to slow down on spending! New tank, stand, pendants, bulbs, ZEO reactor, expensive fish, ect, ect. Its adding up to well over $2000 the past month and a half :(

Disappointed...someone claims to be coming back to "dispel" all these myths and then never shows?

;)


Anyways, started coral snow two days ago and not much cyano left. Just a tiny bit in one spot but it looks to be going away too. This stuff is pretty awesome. Coral polyp extension was pretty crazy while dosing it too :D

You dosing coral snow at the start?

No I never did. So I think coral snow should be used from the beginning to control or prevent cyano.

I am really amazed at how quickly its taken care of the huge outbreak. Literally two doses and its 80% gone. I would say another day or two and no more cyano.


Much better solution in my opinion than red slime remover or especially lights out for a few days.

The guys over on the zeovit forum mentioned using zeozyme rather than coral snow at startup ... i havn't used either :) I used coral snow before i had a full zeo system though, worked nicely.
