NO3, P04 and Alk

[Dan Kyle]

I can't believe you'd see faster growth with Acros as a high KH. You say SPS so if you're not growing acros you can ignore this.

At a high KH you are playing with fire. If any nutrient runs too low the tips will burn (die at the ends). I see incredibly fast growth at 7KH with my acros and they can tolerate more parameter swings at a more natural level. If you run a delightfully filthy tank that's older and you don't obsess with low nutrients, PO4 especially, it may work just fine, but you're playing with fire IMO.

Acros only though, other SPS seem to not care a bit.

Interesting... I don’t have any acros but based on what I’ve read I will keep my KH on the lower end of the scale anyways. I don’t want to risk it even for a biscuit

Sounds like good flow to me.

Keep it stable for another month and see how it goes. Good things take time to happen

Thanks. I will thank you very much for your input. I appreciate it <3

@Dan Kyle, I was under the impression you have had the acros for awhile. I had my tank and acros for 1+ years before I decided to increase the alk. Tank age and rate of increase is in an important factor. Furthermore, your lighting also makes a difference. I had MARS aqua aka the black boxes and theres no way I could've done this. My acro was a very slow grower with those also.

That’s alright. Because I’m new to SPS I wouldn’t buy an Acro just yet. Maybe in the future. I have the Hydra 26HD LED unit over my tank.

My purple and green monti cap's both took about 2 1/2 months to start growing, 8 months later and I wish they would stop haha.

My digi on the other started growing from day 1 but that was from a member here who kept really similar params.

Yeah give them a few more months if anything
