I have taken a hour of the full spectrum period , and will re rent the meter if I could have over nighted it tonight I would have , no over night on BRS probably due to covid
1 month I’ve seen sooner like 2-3 weeks , with no issues why do you ask ?
Hey I am one that has done too much light never had access to a par meter back then. On my last tank I had only two Orphek Atlantiks on a 72x30x30 tank and everything grew some grew so fast you could see daily growth. I ran a 12 hour lighting but only about 4 hours at 100%. I would have liked 4 of the lights over tank but would not have run them at 100%. The sun may shine more than 12 hours and even give higher par middle of the day but full par is not 8 hrs long.
Same basic parameters I run. Tanks 11 months old. About 2 months ago I lowered alk to 7-7.3 and have seen better colors and growth too.
I run my 8 T5's 4" off the surface and have to much coralline growth lol.
Running 8 or 12 hours? It seems more people I know running T5s get more coralline but they also get good coral color and growth. My next setup which hopefully will be soon is going to be T5 with some led bars for more pop. Pretty much plug and play. I see to many people partially happy with their leds regardless of brand.
I run 4b+ 4c+ 8hrs on and off. Going to 9hrs this weekend to give it a try.
I know most local reefers run leds. Many just cant seem to set them and leave them be.
Have you tried actinics. BRS on 8 tube 4 b+ 2 c+ and 2 actinic
That is so true. Most of the ones I see that look fantastic use lots of fixtures to cut down the shadowing.
Tried 1 and 2 actinic but did not run them more than 3 weeks so no real info on growth.
You like the less blue color you could always try an actinics in place of a b+
I know someone running 4 radions on a 120 and his tank is very nice.
I put the actinics in place of the b+ so 4c+ 2b+ 2 actinics.
Yes the cost of led fixtures is my thoughts. I have seen some nice tanks with Radions but when I see 3 on a 6 foot tank for LPS and softies and would be 4 for an sps tank it will pay for a lot of bulb changes.
They’re not crazy high numbers at all, but this could be a situation where an alk of 7.8 causes an explosion of growth whereas 8.5 does not. There is no “set” alk or par number that will universally grow coral quickly. As we know, many things in this hobby functions within a range. That doesn’t mean any number within that range is the same. It’s a sliding scale with many other factors impacting it. For example, I can think of several instances where a doser failed on a reefer’s tank and they don’t notice it for a week because their corals were suddenly doing awesome and they never thought to check until things slowed back down again as alk got too low. In these instances, 7 or even 6.8 dkh in a VERY odd case that produced better growth versus a more typical 8 dkh.
I feel I could get by with a hybrid as many are going that way with great results.
Goos advice! I experienced the exact same thing going from 8.5 to 7-7.3 where my tank sits now.
400-500 mid depth for 12 hrs is a lot. But is it the only reason? I would not make many changes and would give 6-8 weeks between changes. Which corals show the most growth those on the bottom or those up high. Those with the most flow or those with the least flow. I don't feel alk of 8.5 is a problem as that is where mine was. Some people will say 1 year for a tank to be mature enough for SPS. Have you had any die? If not then you have better luck than most people in two years
