Looking to ID Algae in Sump

I have been looking in to this a bunch. Many vendors are still selling the reactor packages with the led lights wrapped around. I’m wondering if this happens over time as the acrylic gets older, constantly being heat up and cooled. I’m not sure, the reactors used most often are the AquaMaxx though.

Yes that is exactly what it is heat/stress over time. And you'll see it on the AquaMaxx, TLF and the like reactors first as they would most likely be using extruded acrylic where the higher end will use Cast. Both will eventually stress crack from the heat/cooling stress.

Most actual Algae reactors coming out now are the center lite versions with a heatsink running LEDS ran inside a center tube. No heat issues as the heatsink removes that issue. I was planning on doing a DIY version of one of these since it would be super easy, but I have no need for any nutrient export. I actually dose nirtates to keep them detectable.

Those setups are so sweet with the internal light tube but so pricey. I have a ball of chaeto in my sump right now but haven’t saw any growth out of it really. How long does chaeto normal take to see noticeable growth with nitrate and phosphates present?

I’m jealous that you need to dose nitrates. I’m hoping with the upgrade in tank that my bioload is reduced a bit that it lowers in the water volume. Otherwise I will have to stick to the chaeto and vinegar dosing.

I'm not sure on the chaeto growth, I had some in my sump when I started and it started falling apart and died on me. I can't seem to grow it at all. I only run a skimmer, real live rock and Brightwell Xport brick in the sump. I don't carbon dose or anything like that. I dose nirtates to keep them detectable and Iron once a week.

Well that issue can certainly be worked around. I haven't seen it become an issue though. I'll keep an eye out for it.

I am going to start adding stuff I stopped doing slowly every 4-5 days see if anything triggers a return, other than the AA's and Bacteria I no longer feel the need to dose those as the tank has been perfectly fine without either.

VOCs? Volatile Organic Compounds? I think you mean something else?

I still vote that the slime was excess bacteria from liquid carbon dosing.

Good luck with resuming dosing.

No I mean VOC's.

Ohhhh, you've been using air fresheners or something? Why do you think there are actually VOC's in your tank?

Wait, who's the OP in this thread? I'm confused.

No I have not but my wife likes to use sented candles which also contain VOC's, I had her stop for the last few weeks. You can also get a build up from any kind of spray cleaner etc, lots of different stuff has it if.

And YOu obviously know who the OP is, I was offering my experinces on this since it's the same or very similar. DkoKoMan seemed to welcome my findings, I can stop posting in the thread if it's bothersome NP.

I realized after I posted that you weren't the OP. I edited that part in.
