My Algae Turf Scrubber Build

Good deal. So, if I'm reading everything correctly, youre not getting a ton of thick algae growth on the screen because of a lack of light? Have you considered adding those red LEDs that you have in addition to the light you are already using?

Gonna need new lights; those skinny strips aren't going to do anything :O

I believe it... so far I've had it up for four days (just finished it on Friday), and today I've got a light coat of green algae on it; but, it probably will not manifest into anything more than that.

I only used those red LEDs for a few days. I've been using the 23W soft white CFL for the rest of the time.

Day 31's Growth

It's been a while but I was on a mini vacation. Unfortunately, while the tank was on my son's watch, I lost my Frag Farmer's Snowcone Prostrata colony.

I did a cleaning, however, on day 26.

Here's with my new macro lens:

Today, I bought and put on a 42W, 150W equivalent, CFL bulb. This bulb is pretty big but it still fits in a standard reflector. I saw the 200W equivalent and it's huge! So, I'll see how the growth improves with nearly doubling the actual wattage.

Nice! Thanks for sharing!

This is what I am using.

The lights shown will not do well in an ATS. I am removing them now, so be careful what you buy.

 

[SantaMonica]

There is a 45w version of it that will, however.

 

[Windy]

How do you know that?

Without quoting a post, I'm not sure who you're addressing.

Regardless, I'm sticking with this 42W CFL for this prototype.

Day 34's Growth

This was taken under natural daylight

This lousy picture is after the second cleaning today:

 

[SantaMonica]

Need to clean all that dark stuff off with a brush so you can see the white screen.

Light is too little.

 

[labas39]

Light is too little.

My understanding is that a lot of people have success with 23W CFL, 100W equivalent, bulbs. I just increased mine to 42W CFL, 150W equivalent, so I'm getting to think that I have enough light.

I can do a little better cleaning but I'm going to stick with this bulb for now.

 

[Bad Company]

I get great growth with a 23W (100W equivalent) CFL in an 8" reflector on one side, and a 27W LED PAR 38 grow lamp on the other. In fact, the $3 CFL seems to grow better than the $60 Grow LED.

 

[SantaMonica]

Dark growth tells you that the light is too little for the nutrients. At the least you can increase hours.

 

[labas39]

I did clean the screen pretty much down to the white and it's kind of like starting over for the third time.

After I did that, however, I noticed that there was a lot less algea on my zoa frags. Maybe I should have let it be.

It looks like you're getting great growth! Can you share the details on those lights?

I used to use them on my display tank but I've gone for the it2080's now
