Reefoholic April 13, 2011 April 13, 2011 Hey everyone, I accidentally left seaweed on the clipper in the tank for almost 12 hours before I went to work this morning and when I came home from work tonight the water was all cloudy. I did a minor water change and cleaned out the Cascade filter. Despite all these and the fact that it has been almost 3 hours since I did all that, the water is still cloudy!!! Such a bummer that I forgot the sea-weed in there. So much for caring for my tang! Any ideas? Do you think the water will clear up soon?
Reefoholic April 13, 2011 Author April 13, 2011 should have I changed the carbon in the filter? It is only 2 weeks old!
treesprite April 13, 2011 April 13, 2011 Do you mean the dried stuff (like nori) or something live and fresh? I leave the dried nori in my tank a couple days at a time and my water has never gotten cloudy from it. Are you sure it's not some kind of algae bloom? Or perhaps the results of reproducing caulerpa?
Guest Rixon Hewit April 13, 2011 April 13, 2011 You should change the Carbon it would clear things up
Coral Hind April 13, 2011 April 13, 2011 Nori shouldn't make the water cloudy that fast. You need to look for other issues. Did you add any additives like buffers, strontium, or calcium that morning? What is your stocking leveling like? High ammonia levels can also cause the water to cloud as well as bacterial blooms.
treesprite April 13, 2011 April 13, 2011 (edited) That's what I meant - bacteria bloom not algae bloom - duh. It's happened to me a couple times. It can deplete oxygen level, so if that's what it is, a skimmer and really good circulation would help. Which brings another thought to mind. Did you dose anything for water quality control that either has bacteria in it, or is a carbon source such as vodka, vinegar, or sugar? Do you have a small child who may have tried to feed the fish (either fish food or people food)? Edited April 13, 2011 by treesprite
beatle April 13, 2011 April 13, 2011 I had a bloom show up when I added some dry (previously live) rock. The die off nuked the tank. A 20g is smaller and is more sensitive to changes in feeding, or a death in the tank. The salinity and temperature can be swung more quickly as well, which can cause issues.
Coral Hind April 13, 2011 April 13, 2011 Did you dose anything for water quality control that either has bacteria in it, or is a carbon source such as vodka, vinegar, or sugar? That brings up a good point Forrest. Some of the Nori that is made for sushi is soaked in a sugar stock before pressing and drying.
treesprite April 14, 2011 April 14, 2011 That brings up a good point Forrest. Some of the Nori that is made for sushi is soaked in a sugar stock before pressing and drying. How would a person know? Would it have sugar (in whatever form) on the ingredients list?
Reefoholic April 14, 2011 Author April 14, 2011 The water is all crystal clear now guys! I don't honestly know what the reason was. I checked nitrites, ammonia and nitrates and everything is good. I had sudden brown/red algae appearance on the rocks and the sand tho. I am not sure what triggered the cloudiness. The fishes and the coral look normal tho. As I said before, I did a minor water change and washed out the canister filter and everything was back to pristine clear normal in the morning. What could be the reason for the algae?
