So I’ve been trying to encourage dense plant growth while getting rid of algae and bring out the color. This has mostly worked for me, but my plants really don’t have quite the color that I want. My Starogyne Repens have some green spot algae on their leaves, some have holes, some are yellowing. My Hygrophila pinnadifida has some missing leaf tips, too, despite the fact that it still grows (although only horizontally). My Fissidens moss is also a bit brown in some areas and lacks the deep green that lots of other Fissidens has.
My algae issues are nowhere as bad as others, but I still notice algae on my rocks, plants, and glass and would rather try to get to the root of the problem.
I have a 40 gallon breeder with a fluval 206 canister filter, surface skimmer, and a hydor 240 powerhead for water circulation.
For lighting, I have a Finnex Planted + with medium-to-high light (I don’t know how I would measure par)
For my CO2, I have a diffuser with about 1-2 bubbles per second.
pH: 7.0 (w/o CO2), ~6-6.2 w/ CO2
Temperature ~23C (~74F)
GH: 35.8 ppm
KH: 3 dKH
I originally used pps pro, but got sick of the liquid dosing and I expected that my plants weren’t really getting all the nutrients that they needed so I have been dosing the following dry EI dosing for about 2-3 weeks now:
MgSO4 (1/4 teaspoons)
KNO3 1.8 gm (approximately 1/4 teaspoons)
KH2PO4 282 mg (approximately 1/16 teaspoons)
Plantex CSM+B 1.2 gm (approximately 1/4 teaspoons)
Just started: K2SO4 754.5 mg (approximately 1/8 teaspoons)
I add 5mL of Excel daily or every other day and dose Aquavitro Envy once a week.
So here are my main questions:
1) Are there any parts of my dosing that I should change? Should I be adding MgSO4 even though most EI recommendations don’t include it? Should I decrease my Plantex dosage at all? Do I need to dose KNO3 even though I have nitrates from fish
2) Should I think about changing my flow in any way since some of the lower leaves seem to die off?
3) Should I try to buffer my pH, GH, or KH in any way?
4) Should I increase/ decrease my lighting and/ or CO2?
