One of these days, they'll be found sucking the slime coat of your fish as they reach maturity.

There's a mention of black algae control near the end of this web link...Thanks for the link but does this also apply towards black algae? My tank developed this algae approx a month ago. My dealer sggested a flying fox (too aggressive) or alternating the lighting. He said by alternating the lighting, it can throw off the algae and it may die off...has anyone heard of this?
Thanks!

3 UPD Catfish
Several regular snails and some spiral snails
2 Cory Cats
1 - 4 Amano Shrimp
1 Bristlenose Cat
Artificial Plants: Various silk plants

I believe I have algae bloom as my water has a green tinge to it. I have about every bottom fish known to man and a few Amano shrimp. I run my lights for 12 hours a day (they are on a timer) and I do weekly water changes, but within 3 days the water is cloudy and green again.
Is there something else I can do? Since I have put the Flora Base in my tank, I have had nothing but troubles. All my tests are perfectly balanced, and I even changed my filter thinking that it wasn't working properly. The fish seem ok, I just get tired of seeing an icky tank.
Can someone help me?
Thanks

hi this may sound unusual but you could try planting willow tree cuttings in the tank substrate ; willow is a proloific growing plant and will take root in your tank even submerged . I have even seen willow after it has been put through a woodchipper start to sprout . The willow should out compete the algae for nutrients and you remove it after, as it will not survive ultimately. I suppose if you dont like the idea of using a terrestrial plant you could try something fast growing like hygrophilla polysperma and same with the willow cuttings if you dont like it after you have got rid of the green water you can rip it out . Hope that doesnt sound like too whacky an idea , all the best graham7 .
Hi everyone! Check, your tank is out of balance. Also, you will need to replace that Smartpaq with a daylight bulb. I use the sunpaq 6700k/10000k. With 65 watts of light over a 20g you need ferts and co2. Keep co2 above 30 ppm, and shoot for 10ppm nitrate(KNO3), 1ppm phosphate(KH2PO4), 20ppm potassium (K2SO4) and dose traces(Flourish) and your tank will explode with growth. You can get these from Greg Watson.com for cheap, and use Tom Barr's estimative index to find out how much to dose. For now you can try a 3-5 day blackout to kill some of the algae.
