Algae scrubber does it work?

Recommended Posts

Hello, I was thinking about an algae scrubber. Does anybody know if it really works on reducing phos and Nitrates? I have a 40 gallon reef tank with a 10 gallon diy sump. Does anybody here uses algae scrubber?

 

 

thanks,

Yep I run one on my RSR Nano 21 gal with 7 gal sump. I had to start dosing nirates as mine are not detectable and never have been since the AS took off (takes 2-3 weeks to really get going)

I feed veryheavy for my bio load, also feed reef energy A+B every day and reef roids and poly booster every second day. Nirates even dosing 0.5  Phos .022-0.028

Definitely works, although I don't use it for nutrient reduction. I used it to keep algea out of my display. It also allows me to feed really heavily, fish and corals.

Thank you guys. But from what i heard it consumes nitrates and phosphates. I'm I correct?

100% that's what I use it for and my levels stay at 0 nitrates unless I does and .025 on Phos as I said last post.

Ok. I just finished my DIY algae scrubber. Is the light enough? i have 2pcs 5w red LED bulbs in there so a total of 10w. Would that work or i need to add a royal blue on it? I put it in the sump. light is on 16hrs a day. Please give me your thoughts about my build or if you can suggest how can i boost it so the algae will start to grow.

 

 

thanks guys!

Really depends on the size of the screen for the amount of light you have. You will also want a min of 35GPH per inch of screen length, I run 40 GPH per inch.

 

Also there is no way to boost it, just good light and proper water flow. You should start with 12hrs on/off for light or less and ramp that up after it takes hold. I started with 10hrs on and 14hrs off. It took about 3-4 weeks to really take off and grow, make sure to clean the screen once a week regarless of what is growing on there. And by clean I mean just scrap don't take it all off jsut the top layers.

The screen i have is 3" x 7" then the bubbles comes from the bottom. So i need to up more on the flow then. I think my flow is less than 25gph. I will try to lower it to 12hrs a day. So the growth will start around 3rd week?

That is a pretty tiny screen, not sure that is going to get you what your after. Mine is 6 X 6.5 double sided which means I can feed heavy for a tank my size Approx 1-1.5 cubes a day.

 

I believe the upflow are even less effective as the waterfall builds, but I'm not 100% as I never researched that type as they seem to be a odd build. Sorry I can't help you on that type, but I would suggest looking into making your build at least 2X the size if you plan to feed upward of 1 cube or more a day.

 

And yes 3-4 weeks it what it took mine to really start growing well, but you must clean every week or it will hinder the inital gorw process.

I have a waterfall style as well but i have to mod it. From the overflow box drain to the waterflow AS. it is a 10' x 12' scrubber waterfall style. If I'm going to use that. How may LED lights should I use? and it will be on one side only. My sump is a 10 gallon DIY. my DT is a 40 gallon reef.

You keep quoting tank ans sump size, it is irrelevant. You size it based on how much you feed, if you feed very little you will not need a very large AS. If you feed heavy you need a large size.

Here it's easier if you read up on them before going too much further and not getting the results your after.

I feed my fishes 1 cube per day. So i think the waterfall is much better for this project. I will post pictures once i installed it. I will get 2 2700-3000k CFL bulbs today with that clip on light. I'll update you soon. thanks!

I would say yes as long as you have enough flow going through it.
