Well where do I start, I'm gonna try my hand at a DIY algae scrubber, my reason to try this is my nitrates are always at 20, even when I first set the tank up they were 20, not sure how, I think it may be leaching from the base rock I got but that's just a guess, anyway this algae scrubber is going to be a in sump scrubber and underwater, Id hate the sound of a waterfall in my front room so that option is out, I'm sort of copying an algae scrubber that's available to buy but my own version lol.
I have a few quick designs, and I have a electrical technician on hand who is going to make the led
side of things, my first problem is finding the right kind of plastic that won't leach anything into my tank, any ideas?
I've found that
PETE- polyethylene terephthalate
HDPE- High density polyethylene
or V- polyvinyl chloride or vinyl
LDPE- low density polyethylene
Are all considered the most aquarium safe plastics but has anyone used polycarbonate plastic in their tanks? If so any problems?
The idea is the air bubbles will push water (which will enter through the bottom of the scrubber) over the scrubber pad and the water will then be pushed out thru two holes at the top if you get what I mean?
Any other suggestions, flaws or heads ups anyone has come across making an algae scrubber or can see in this idea then plz jump in and let me know. Here's a few design ideas anyway.
