Gracilaria will starve without some sort of iron. I've learned this the hard way a few times. They also like light, and I don't think your light is cutting it for them. I've learned to treat my gracilaria like a SPS coral in regards to lighting - intense. Different flows didn't really matter. Your low alk is not helping either. Every time my alk has every dropped below 8, I have issues with my macro.
I don't like that you have all this macro, even the "slime algae" and still have nitrate and phosphate readings. What test kits are you using?
How old are the tanks?
To figure out flow there's really two ways: Do you have these fuges in sumps where the overflow is feeding into them, or are you pumping water out of your tank/sump into the fuges and then draining back into tank/sump?
My chaeto really doesn't like very much flow. I'm currently only growing chaeto, grage caulerpa, caulerpa prolifera, caulerpa rasmosa, halimeda and hair algae (I let it grow in my fuge) I also have a red fuzzy, hair algae- like macro that grows in my fuge, but I have no idea what it actually is....
My fuge is a 55G, connected to my 180 reef tank with a 1300GPH Triton 5(deep blue) pump that pumps out of my sump and into my fuge. My fuge is set up as a frag tank/display refugium and really runs more as an attached tank that shares the same sump as the 180. BTW: the triton pump sucks, don't buy one.
Every time I have every tried to run a fuge that is less than 1/3 the tank volume, I have issues. I don't know why, but I do.
Sorry to hijack Justpeachy...
BTLD,
I have the same Red fuzzy hair algae. I have read on the big forum that it is kinda bad. There are a few threads over there that talk about how to get rid of it. What are your thoughts??? I am on the fence on it. It grows pretty fast and I harvest the heck out of it. It is only in my fuge and not a trace in the DT (125g with 67g sump). I was putting together a plan to nuke my sump and restart it fresh. But if you have had it for a while and don't see any issues... I may change my plan of attack. You can PM me if this is too much of a hijack to the OP.
Justpeachy, Sorry again...And we would love to see some pics of your DT... If you got some.. Post em up!!!!
