Good Morning,
I had to drain my 600 gallon pond. It had a leak in the liner. While I rebuild the pond, I have put my RES in a outdoor aquarium. Things went well for the first 2 weeks, water was nice and clear and then the algae bloom hit me. I put a UV sterilizer in which took about a week to clear up the green funk. It came back with a vengeance and has been hard to get rid of ever since, even doing 50% water changes with new media has not helped. Any suggestions? My tiny RES is in a 20 gallon tank for the meantime. I have been thinking of an external filter, right now I have a Fluval C4 with an additional 5W submersible UV light. Any suggestions are welcome.
