Help with left side of 75G
Hi. I'm really hoping the someone can give me suggestions/help regarding the left side of my 75G Angel/Festivum aquarium; attached pictures below.
I set the tank up, cycled etc. back in February.
Substrate: Flourite dark and pool filter sand with peat moss underneath about 2/3rds
Light: Fluval Fresh and Plant 2.0
Filtration: Fluval 406 and Seachem Tidal 55 HOB (soon to switch for Eheim canister)
Ammonia - 0ppm
Nitrites - 0ppm
Nitrates - 20ppm
KH - 6-7
GH - 5
DIY CO2 (citric acid/baking soda - I know)
Ferts: NilocG Thrive and Seachem Iron, also Flourish tabs
It seems really strange to me that the left approximately 1/3rd of the tank, the side that is by the canister output and consequently where there are no floating plants, is the part of my tank that has a bad algae problem. The other 2/3rds, where light is really blocked by the dwarf lettuce and Salvinia minima and now crazed Brazilian Pennywort, has a very little algae. I would have thought that that would be the side with the algae problem?
Worse though for the left side is that it seems that no plants really are happy there except for some dwarf Sag. I have 1 Aponogeton boivinianus where the leaves turn brown as soon as they get big and now they are totally covered with light green hair algae. I have Valls, corkscrew and jungle, both of which are constantly melting and are also now mostly covered in hair algae. The corkscrew has been in the longest and went through the usual "newly planted" melt and had grown back to be quite tall at one point. The left back corner and sides are have the exact same substrate as the right side where I have no problem with swords and Bacopa.
Does anyone have any ideas about why this one side is so cursed? I am not asking why I have algae, I figure that has to do with the DIY CO2, but why there would be such a difference between the 2 sides of the tank? How about any suggestions for different plants for the back and left sides? I don't think I can take the poor Aponogeton much longer, nor the Vals if there is no hope for them growing longer than 3"!
Thank you very much in advance for your ideas!
