Do you run algae scrubbers on freshwater or saltwater?

  1. Hey, all!

    My name is Zach, and I'm glad to be on this forum. The algae-scrubber basics have come in so handy to me lately, and I'm glad for the compendium of knowledge on this site. In fact, after reading up, I don't know why the whole world doesn't scrub with algae! (Clever marketing on filter-makers' part?) All that being said, I'm glad to be here now, and this is my first foray into algae scrubbing. Though I realize this is primarily a saltwater method, I'm a freshwater enthusiast with a soft spot for Tanganyikan cichlids. I realize algae scrubbing behave differently in freshwater. Nevertheless, I'm going to try it out, as my cichlids require constant feeding and my tap comes out higher in Nitrates than I would like, making waste management a nightmare. I'm hoping promoting some controlled algae growth will help make water changes a little more effective—and plus I get to do some fun DIY on the side! Win-win, eh?

    For my build I went extremely low-budget, trying to find out what I could use as cheap substitutes for things like acrylic boxes. I currently only run a single 55 gallon tank, with a stand modified to accommodate a small 20 gallon, 2 chambered sump. With the limited space, my build is relatively simple. I have a single L-shaped pipe running off a cheap Hyyger pump from Amazon (https://www.amazon.com/hygger-Subme...ump&qid=1595280080&s=pet-supplies&sr=1-7&th=1), with an 8x6" screen and an 8" slot.

    For my lights I'm using two aquaponics/indoor grow lights, replete with heat sinks (they get pretty hot) (https://www.amazon.com/ACKE-espectr...ords=aquaponics+lights&qid=1595280696&sr=8-13).

    One thing I noticed about the old guidelines (which I see are from nearly 7 years ago) is that LEDs had not been well studied, and easy availability of LED grow-lights was seemingly non-existent. Now, in 2020, plant-growing LEDs were cheap and easy to find, and they're growing algae just fine. I'm quite happy with them.

    For my housing (and I'm quite proud of this), I used a $4 sterilite clear plastic box with a clamp-on lid from Walmart. By taping off (or cutting out) an area where the lights will go and painting the rest black with Krylon, I have a $5 DIY housing, replete with lid. A couple slots roughly cut on the ends serve as supports for the pipe.


    The end result is what you see here. Since the housing came about a week after my initial build (I was losing a lot of water to splashing), my pipe is actually shorter than it ought to be. When I get the time, I'll cut another slot pipe and install it so as to properly center the screen between the lights. For the moment the algae is growing a bit off-center, but I'm not too terribly worried about it.



    The scrubber has been running for about 2 weeks and began to show a coating of light green about 4 days ago. (Not visible under pink, lights, surprisingly! I have to take a flashlight under there to see my growth.) I've upped the photo-period to 20 hours (24/7 with an hour break for cooling every 5 hours), as I've seen that a 24/7 setup is necessary for freshwater setups.

    Let me know what you think/if you have any suggestions! :)
