Ok.....Update.....
After last week's water change I noticed new beautiful growth on rotalas. I love these plants because the new growth looks like flowers at the top. Yay!!!
I dosed last week only the weekly suggestion of the FlourinMulti and FlourinAxis. Both are 5ml/50gallons. I stopped daily dosing though the daily dosing at the end of a week is 5ml.
I noticed stringy algae growing on my plants!!! Not happy about this. From reading I know that it'll eventually go away. Others say use Excel. I checked it out today. Excel is a bioavailable carbon source. The same as the FlourinAxis. I did not pick it up. I did small water change today but since I use an Aqueon siphon that hooks up to the sink I don't know exactly how many gallons I removed. This leads to guesstimating how much water conditioner to use. As I turn the siphon in reverse after adjusting temperature I use a syringe to drip the water conditioner into the tank before I start refilling. I hold the hose above the water and move it back and forth to mix with the conditioner while filling. I can use the siphon to remove water and a bucket and measure the conditioner per gallon and refill if a potential cause of algae is maybe using too much water conditioner.
I'm a little baffled because my research told me that this type of algae is also cause by too much nutrients. I checked before the WC and nitrates were at 10-20ppm. Since I had no plant growth in a few weeks I got some hornwort to help choke out the algae. It was also time to get some new plants.
Is this type of algae dangerous to my fish? I often catch my angles grazing on the plants. I wouldn't mind if they ate it but there's too much for them to clean it up. Are there any other ways to get rid of it? I wouldn't mind picking the stuff off but, again, there's so much and I would have to take the plants out to really get it. I think for me the easier thing is to wait it out until it goes away itself.
A quick about my tank
50 gallons
5 Angels (I got a new one)
3 Albino Cories
8 Black Neon Tetras
1 Cat Shark (Columbian Shark)
3 (but I can only see 2) Otocinclus
I feed everyday with TetraColor Tropical Crisps. I probably feed a little too much because I do let some go down for the cories and the cat shark. I feed every 3rd day 1 Aqueon bottom feeder tablet for the cories and cat shark. The angels pig out on this too. I also feed with some freeze dried bloodworms 1 a week and tubifex worms 1 a weeks or so.
Any insight would be appreciated.
