So here is a pic of my 220g tank

Tank2379 · 01/04/2018, 09:40 PM

Are these being discontinued?

Thanks

I have been really happy with the AP700. Most of the corals in the tank have been grown from small frags and have really surprised me how quickly they have grown under these lights.

What setting color wise are you sitting at?

Zitadel · 01/06/2018, 03:07 AM

Lights start at the bluest setting then gradually moving towards whiter colors. The maximum 75% intensity it is set at the center of the color wheel between the most white and the most blue.

Awesome I’ve kept mine at the third below midline. I’m debating making it more white though.

Does you light fan ever shuts down ? I noticed mine working all the time even when lights are off via schedule

reefer31 · 01/11/2018, 10:26 PM

Fans shut down for me

Just curious as to how long you guys have the high intensity running? I’ve kept the same schedule as my mh schedule so like 8 hours at high intensity. I’m thinking it may be too high for too long as these bad boys are powerful. Any thoughts?

Lighting intensity needs to match the nutrient level in your system. You can not make any assumptions about your system based on others experience, other than the fact these lights grow coral.

Simple starting points.

Corals mostly pale and whiteish?: increase nutrients, lower ALK 7-8 dKH, lower light intensity.

Corals very dark/brown out?: decrease nutrients, increase ALK 9-10 dKH, increase intensity.

That is a very simple break down and you can do all or one to try and fix it, depends on your system, I would start with one. There are a lot of subtleties hidden in that simple breakdown so be sure you research each one and document/track changes. Also improvements can take weeks probably months to show themselves.

I recently reduced my lights from 90% to 75% and started getting better growth about 2-3 weeks later. Even if the coral can handle more intensity doesn’t mean it’s the ideal amount of light.

I’ve pretty much found the same thing that you just said about these lights. I was just curious as to duration of intensity. And you stating that you dropped your intensity answers it haha. I don’t think I will be able to push much past the 70% mark at least in my tank.

Just spoke with Kessil here are some questions and answers I asked if anybody interested:

1. Does the fan must shut off while the light is off via schedule ? Because mine looks like working all night long.
The fan does run even if the light's schedule is off. The fan will run for as long as the power supply is connected.

2. I noticed sometimes light can just go off and next second on again. I am not sure why is that happening. Can you please explain ?
There is a known issue with the AP700's firmware where it will randomly turn off and on for a second. Our software designers are working on fixing this issue with a new firmware. It is undergoing testing mode and as soon as the firmware update is available, we can send you to notify you.

Are there different generations/versions to the AP700? I am considering buying a used light but I wasn't sure if I was going to miss out on something compared to buying a brand new one (other than decreased LED life). Basically, have they changed anything in the last 2 years? Thanks!

No, firmware upgrades only

No, just newer firmwares which are downloadable.

I forgot to mention that I also have two 80watt T5s with ATI bulbs on for 6 hours also. So my PAR is in the higher range, 300-450+.

Honestly you can have a lot of light as long as: corals have been acclimated, proper nutrition, adequate flow, and slow steady light increases.

There are two acclimation. First is upgrading to AP700s with current live stock. Second is adding new corals, need to acclimate to your systems and the lighting. I place my corals on the Sand bed or very low for at least a month. Corals will die faster from too much light than not enough.

Yes my tank´s water volume is 760 liters with sump included. Tank dimensions are in metrics 160cm x 80cm x 65cm.

I just removed my two Ocean Revive T247 fixtures and replaced them with a Kessil AP700 fixture. The new AP700 is 10" above the water over a mixed reef tank. I do not want to bleach my corals so what intensity would you recommend I start at? The old T247 lights were set at 75% blue, 30% white if that helps. Would 50% intensity be to much?

Yes, maybe. It’s better to just start low and work your way up. I always recommend 35% with 5% increases weekly if everything is doing well. If you see stress don’t lower the lights just wait another week or more. When you get to 50% any increases need to be made slower, if at all needed.

The key here is make sure your corals have food and/or nutrients, and high flow.
