Hello...Seeking Science Fair Help

Welcome to Algae Scrubbing Join our community today
  1. Hello, everybody!
    My name is Mike and my youngest (of 4) daughter is Mel, together we have a 58 gal oceanic reef tank.
    We have been doing a ton of reading on reefkeeping, filtration, water parameters etc...Algae scrubbers have intrigued both of us for some time now.
    It is that time of year, The Science Fair!!
    We live near a lake that experiences algae blooms that actually close down some of the beaches in the summer. Mel and I were talking and she asked why we couldn't use an algea scrubber on the lake? Thus started our quest for information on scrubbers and how to go about testing this theory.
    We decided to fill 2 20gal. tanks with lake water and light the them with an LED fixture we have laying around.
    One tank will have just a powerhead circulating the water, the other we thought to use an ATS on and monitor parameters in both.
    The questions are: Would the water need to be heated to grow algea?
    We have watched dozens of videos on DIY builds and started thinking maybe just buying one would be easier and not very much more $ after buying all the materials needed. Any help? Thanks!

    For such an experiment, for it to be pertinent, I would think you would not want to heat the water unless you have it in a location where the water temp would be cooler than the lake water that experiences the issue at that time of the year. So, if you had it in your basement and it was 60F down there in the winter, you might heat it to 70F or something.

    Then, to simulate your operating enviroment, you would want to use what you would use outside - sunlight. Seeing as that might be difficult, a full-spectrum light might be a better choice.

    Now you have to take in the volume factor - for a lake, you are going to need to do a raceway scrubber, that's the only way to get the sheer surface area you would need. Obviously for the experiment, this explodes the size/cost so you might just consider this a subset and go with a waterfall and a few floodlights, a slot pipe, screen, and pump and that's it. It really should not be a big expenditure I wouldn't think

    There are many similar types of experiments that people (universities, etc) have done to try and clean up environments in this way. I was digging for an article but I can't seem to find it...
     
  3. Thanks for the info! We will heat the water to what the average temp is in the summer.
    BTW your scrubbers look incredible!! One day!
