Why am I getting algae on my glass??

[tew47]

Everyday I have to scrub my glass. I have a 93 cube that is lit by a radion and 4 T5s. Radion ramps up at 9am and is off a little after 7pm, T5s are on for 6hrs.

Water parameters

Phosphate 0
Nitrate 0
Calcium 440
Dkh 11
Temp 79-80
Salienty 1.025

Running gfo, have a huge bag of chemi pure eleite in my sump as well as a octopus 110 skimmer. I dose probido every 2 weeks and do about 30gallons of water changes a mth.

I scrubbed my glass this am at 8 and it could already use another cleaning.

Its natural . Nothing you can really do about it. It's actually a good thing.

It could be bacteria.

What is your intensity or overall brightness. I turned mine down and more blue and much less glass cleaning. Also since I lowered phosphates over flow box is cleaner

 

[tew47]

I have a modified sps +ab profile going at 100%

 

[BryanCaruso]

Yeah that will do it

Which test kits are you using? You photonperiod is very long but I would doubt those tests are accurate. With 0.0 nitrate and 0.02 phosphate I clean my glass every week or so. I have 2 Radion G3 on AB+ then on the other SPS program.

I have a Hanna for phosphates and API for nitrates

 

[Pife]

Which hanna? You're the first person I've heard of running at 100 percent on a radion.

 

[tew47]

The low level Hanna, I have the wide angle lens

 

[BryanCaruso]

Here are some par number for a wide angle lens vs regular. I am not familiar with the old radions. And the pic says something about orange both sets look orange to me??? But the main point is from regular lens to wide angle 30% more for equal par I would at least drop to 75%

I have a Hanna for phosphates and API for nitrates

Toss the API and go check the Hanna somewhere. The LFS in my area will check your water with quality test kits.

Hanna ultra low for phosphates is the only way to go.
I have tried many but Red Sea for nitrate works best for me.

If you had 0.0 readings on both younwood not get algae on the glass. Especially not in just a few hours. Imwookd guess too much light hitting the glass, your test kits are not good or your algae growth is hiding the readings.

I used a par meter to test and got the numbers I was looking for at 100%

I'll go pick up a better nitrate test tomorrow. Everything looks extremely happy and I am getting great growth on all my sps (roughly 50 pieces)

I kinda have my radionG4 crankin too even though I turned it down some Tuesday and then some more today

Pictures could help with a diagnosis. Definitely couldn't hurt. How much do you feed and what do you feed?

 

[tew47]

I'll let it build up throughout the day, I cleaned my glass late last night.

I feed about a quarter size piece of LRS reef frenzy a day. Reef roids 2-3 times a week

I also run Radion G3 at 100% on SB+

 

[tew47]

I cleaned my glass at 7pm last night, so this is roughly 18hrs

Top half of the pic is clean, bottom is 18hrs since last cleaning

Looked like my glass after a day before I turned my lights down. I'm thinking about making mine more blue after looking at the tank not sure tho yet
