Often you need a little gfo or other phosphate reducer every once in awhile to keep the ratio. Phosphate tends to build up in our tanks. What you don't want to do is brong phosphate to zero with a reducer. If there is no phosphate then the carbon dosing won't work (won't lower nitrate. ..it needs both).

Thanks Mindy. I have never bothered much with a phosphate measure, as Im always running gfo anyways. Guess I will have to if I go with the carbon dosing. II find my Salifert test kit not the easiest to read however.

Found this on Prodibio.

"BioPtim
This is your carbon source as found in many other ULN systems. The difference is again you only dose every two weeks. BioPtim contains a multitude of essentials additives for feeding the bacterial colony in your system and in doing so lowering your nitrates and PO4 levels."

Hmmm. Im still going to start with the Zeo carbon source product however. In addition to my Prodibio.

Maybe but I have trouble with adding a unknown about of "carbon source" to the system. Any other carbon driven tank is a daily requirement

Thanks for the comments. Im ordering the Zeo and see how that does.

I don't believe that is bryopsis. For those that are combatting it, the Tech M does work. It took me two attempts before I was successful. It didn't kill it, but it stopped it from returning when I weeded it, so I feel that it worked!

Just FYI, the guy that made the Tech M "proprietary" blend also made the Brightwell stuff, and so both are alleged to work. There is some ingredient in them that isn't found in bulk products, and so generally, the bulk stuff doesn't work well in dealing with bryopsis.

I like the Prodibio BioDigest and BiOptim but I find they are only useful to get from LNS to ULNS. They aren't as powerful as daily-dosed carbon products.

Also, you'll need a different phosphate kit for ULNS. Hanna ULR HI736 is good but you need to know a few tricks to get accurate readings. I've heard good things about the Red Sea Pro Phosphate too and apparently it doesn't require any tricks, but haven't used it myself yet. Soon though...

A few questions if I could. My sps are doing so well Im scared of harming them fighting the algae. But it does need to go. Seems almost impossible to scrub, even using a stainless steel brush.

I have Kent mag coming but if not bryopsis, thats out.

Also have AlgaFix coming but those products scare the pants of me. May be what I have to use though.

What if I buy the Zeo product and fight it that way, going ULNS?

Any thoughts or suggestions.

Thanks

I haven't heard of either of those products harming SPS.

Ya thats the impression I got from the threads on RC. But then I can screw anything up.....:lol:
