So with little to no macro algae growth would you think I'm po4 limited? Or is the nasty stuff just pulling it out of the water column? I did some reading and it seems some people think dinos like ultra low po4.
Also wanted to say that coralline is starting to grow pretty well.

FWIW, I'd be surprised if dinos actually prefer low phosphate (after all, they don't have to take it up if they don't need it), but they seem to thrive at levels that may be stressful to other creatures.

Lol. So you think it is possible po4 is limited? But what about coralline, would it be growing? I mean it's not exploding but it had started where before when this "algae" was at full bloom it wasn't anywhere to be found. I just don't know wether to get more aggressive with gfo and mb7 or leave it alone. I certainly don't want this algae exploding again. I actually ran gfo from day 1 cause I used dry rock and a little live rock I had in a nano and was afraid of the dry rock leeching po4.

People generally do not have good success treating dinos with low nutrients, so if you believe they are at appropriate levels for a normal reef tank, I'd look to other possible methods.

So I shut down the gfo reactor to see what happens, I was thinking of dosing po4 but seemed insane. Lol. So now I have some red cyano popped up on the fuge walls. Po4 still zero. No3 dropped to zero. I'm wondering if po4 was so low all bacteria was having trouble thriving. I'm going to keep an eye on the gunk algae in the dt. If it gets worse I'll turn the gfo back on, if it starts to die off I'll leave things alone until I start to get a measurable po4 level. Make sense? Thanks

That sounds like a fine plan.
