Too much water movement/filtration?
I have had my 29g fresh water tank for about a year and a half now. I started out with (2) AC 50 filters and some various plants. The tank was about 20% planted max at any one time.
Fast forward to today: I now have a Eheim Classic 250, (1) AC 50 filter and a
Hydor Koralia Nano 240. I have some plants and about a dozen fish, and 5 Amano shrimp.
I am thinking about getting some floating plants and feel that perhaps my water flow is too much, as I feel that the floaters will just get swirled around.
I also have had an increase in what I believe is black beard algae, which grows on my bacopa, amazon swords and my dwarf sag, but not on the one wisteria that I have left in the tank.
I have heard that an increase in oxygenated water can contribute to this outbreak. I change 50% of the water once a week and feed once a day (i dont believe I am overdoing it).
I know some of you will probably pick this post apart with what I have said, but I am interested in any feedback with regards to my tank.
PS- When I had the tank filled with just wistera I never had an algae problem.
Light- Planted Plus (on for 5 hours a day).
Filters- (1) AC 50, (1) Eheim Classic 250, and (not a pump) a Hydor nano 240.
Heater- 15w Marineland
Ferts- I dose well below EI for macros and micros, as I dont have a large abundance of plants. Hence the reason I am thinking of floaters and some ludwigia, and chopping the bacopa down to rid it of the algae.
Again, any help would be great.
