I'm bloody glad you dodged that alk bullet mate, sorry for not posting sooner but i'll be jabbering away here regularly from now on lol. It sounds like the reef is slowly settling in and starting to look after itself without the need for too much mechanical filtration, i know it takes a while for the entire mini ecosystem you're trying to create to come to life but month by month the bio life will increase in response to your feeding levels and husbandry techniques and the water will be carrying all many of yummy stuff for the acros.

I know it's not ready for a FTS yet but i think you better give us a few closeups at least to keep us going...........:beer:
How much GFO do you have in the reactor mate, i'm sure others want to know. If you want a second opinion on that hybrid light unit i'd be happy for you to send it to me for evaluation......... i'll send you my blue/white LED unit to use lol - sounds like a fair swap to me mate :smokin:
What do you think of the lighting now, any colors giving problems under it (doubt that). What i'm really asking is do you think the ATI hybrid removes spectrum from the acro equation just as Radiums do imo. From the colors your getting i'm pretty sure i already know the answer lol.
Looking forward to updates :beer:
Hello mate! I know some people say that Potassium levels dont affect acro growth etc...but after I brought up the Potassium levels, the growth in my acros has took off! I had to adjust my doser again last week as I noticed my alk dropping again!
I am still using filter socks...now you are making me feel like I need to take it out. But the only issue is that the sump gets crap all over it and its a pain to siphon the bottom of all of sections of the sump...
Do you think I should take out the filter sock?
GFO: I use a slow acting GFO brand. Here is the info:

So I am running basically around 10litres per hours through the reactor. I tee'd off a line from the return pump and used a small valve to control how much flow goes through the reactor. I've been using this same GFO brand for many years now and like it better than other brands because it is slower acting and does not strip PO4 too fast. I am using 250mls through the reactor. To be honest I could just do what you have done Biggles and place a few bags of this stuff in the sump and it would work that way too.
ATI Lights: I love this light. I added a Red Acropora Abrotanoides frag yesterday. So I decided to measure the PAR to ensure the Abro was getting enough PAR. The only place left was a piece of space on the bottom of the tank. So I measured the PAR and was quite happy to see that the PAR here is between 300-350.
I have no doubt as to whether this light can colour up my corals. I already see improvements in some of my corals...and remember I had a custom T5/LED Sunpower previously, so the improvement must be due to slightly increased PAR in some areas of the tank and the improved spectral quality due to LED's and more tube combo's.
Let me give you a breakdown of the colours:
Red: My rose Millepora is showing nice colour. It could improve, but I put that down to water quality. I also have a BRIGHT PINK Millepora (not sure of species...but lets call it that for now)...I've never seen anything as HOT PINK as this acro.
Orange: I gave a frag of my Forest Fire Digitata to my LFS yesterday. The polyps are BRIGHT orange. You can even see the orange colour with the tank lights off!
Yellow: I have one deepwater acro with true yellow tips. No issue with this colour.
Green: easiest colour to pull.
Blue: I have MANY blue coloured acros. The blue can also be seen with the lights off. Another easy colour to pull.
Indigo/Violet: I have one deepwater acro which is purple in colour. But it is such a slow grower and taking its time colouring up. However, with the tank lights off, I can see that this acro is actually purple in colour. I think an overly blue spectrum masks the purple tones a little.
So, overall...yeah spectrum wise I'm very happy with the light. PAR: no worries there...IT IS A PAR MONSTER. I get 300-350PAR on my sandbed! :smokin:
Biggles you ship me your lights first and I will then send you my ATI. :lol:
I will post a couple of shots next week....just to keep you guys happy.
