Hi,I've been having on off battle with algae for a few years now and seems at its worst now.Some bba on gravel, and a sort of dust algae on the crypts.
Today, I tested both tap water and aquarium water for phosphate
Results came out high as per picture.Problem is, I tested tap water(test tube on left) and this was also
high!! I do a 30 to 40% water change weekly.Really don't know how to address now and I would love some help please.
Tank details are:
400 litre tank filtered by 2 x Aqua one 1400 ocellaris.
Spray bar running along 2/3 of back wall.
Non co2
Seachem excel Liquid carbon daily
Api leaf zone once a week as instructions
Root taps
Plants are quick growing hydrophilic and sessiflora.A few valllis
who don't seem to mind the excel, plenty of crypts and some slowing growing anubias.Plus one peace lilly, roots immersed but growing out of Tank.
Other parameters:
Nitrite 0
Ph 8 but very stable
Ammonia 0
Nitrate 5ppm
Temp 22 to 23 deg c
Inhabitants:
13 black neon tetras
12 cherry barbs
5 nerite snails.
1 red tail shark
10 x various cory
2 x bristlenose plecos
2 x pearl gourami
I feed 3 times weekly and I have reduced the amount of food lately.
Led lights on 6 hours daily, 6 inches above water line.
I a bit flummoxed as to my next step having tested the phosphate from tap.
Any help would be greatly appreciated as I feel I may have diagnosed the problem but not sure how to address.
Many thanks
Nigel
