My 15-gal with 3WPG
Hello guys,
I have read a few posts regarding algae problem or fear of algae attack. I
am starting to feel a little lucky. I have no serious algae problem since
I started this hobby. I have been doing something right without knowing
how. Perhaps I can share some information on my tank and hope that I can
be of some help.
Dimension: 2ft x 1ft x 1 ft (approx. 15gal)
Lights: 1x15W FL + 1x36W CF
pH: 6.5-7.0
kH: 4-5
GH: 8-10
temperature: 30°C (86°F)
NO3: >20ppm (beyond my test kit range)
PO4: >5ppm (beyond my test kit range)
Fe: 0.25ppm
K: not tested
(adding about 40ppm on top of what is in my tap at water changes and adding
about 2ppm every 2 days)
CO2: CO2 cylinder, injected via ceramic diffuser
Substrate: plain gravel
Fish load (high): 18 cardinals, 4 ottos, 2 SAE, 3 german rams, 6 corys
Plants:
Vallisneria americana
Hydrocotyle leucocephala
Eleocharis acicularis
Elatine triandra
Echindorus tenellus
Hygrophila stricta
Hygrophila deformis
Lobelia cardinalis
Nymphea sp (red tiger lily)
Dosing:
Daily - Seachem Flourish Excel(1.5ml)
Every 2 days - Seachem Flourish(0.75ml), Potassium(2ppm)
Every week - Dennerle S7
Every 2 months - Seachem Flourish tabs
Weekly 50% water change with added Seachem Equilibrium
According to some people, with the fish load, NO3 & PO4 level and high
temperature I have, I will definitely have algae problem. But so far, I
have only one BBA outbreak which I controlled will increased CO2.(Thanks to
info from the APD.) Now, once a month, I just have to scrape the tank
walls of some green spot algae and pick out some blackish hair-like algae
from among my hairgrass. I do have some nice looking moss-like algae on my
drift wood and I left it alone.
I am not sure what was right about the tank. But I hope it can help.
