Hair algae and stunting
Hey guys, I was wondering if anyone could point me in the right direction
Ive always battled green hair algae in my tank, and Im getting very sick of it!
Here are updated stats for my tank. I have to go update my sig
I have a 46gallon bowfront acrylic tank (~174L) with 2x39w 6500K T5 bulbs on for 10 hours a day (12noon-10pm) with a 4hour midday burst (3pm-7pm)of 1x39w 6500K T5 and 1x30w T12 coralife plant lamp (dunno K rating)
Eco-complete substrate only, with some root sticks for my erios
10lb Pressurized co2 tank diffused through a reactor (approx. 3-4bps) comes on 1.5 hours before lights and goes off with lights
3 discus, 10 cardinal tetras, 1 corydora catfish, 1 queen arabesque pleco, 1 clown pleco, 1 otto
erios, toninas, rotalas, ludwigia pantanal, aromatica, a. reneckii, glosso...etc.
Ph is very low....around 6 (havent tested lately)
kh=1 (RO water)
gh=8 (Grumpy's GH Booster)
3ppm KNO3 daily, 0.5ppm PO4/week
seachem trace elements
3ml seachem iron
3ml seachem trace
1ml seachem flourish
Seachem excel 15ml daily
Im having problems with the a. reneckii stunting (curling), and my rotala vietnam and wallichii too
My erio sp. thailand is very unhappy. Its showing yellowing, and blacking on the leaves. I want to try to split this plant, but Im afraid.
My main issue is the green hairy algae that shows up on my slow growers...mainly tonina belem, pantanals and erio thailand.
I think its from too much iron, so I have since stopped adding the 3ml seachem iron daily. I think I get too much iron from the gh booster
The packages says:
"5 grams will add just over 2 dGH to 10 gallons of water and add 0.15ppm iron, 0.07ppm of manganese, 25ppm of potassium. 26.6ppm of calcium and 12ppm of magnesium"
I use the gh booster to add calcium and magnesium. At water change I add 30 grams of this stuff.....and an extra 5grams of potassium. I believe I add 4.35ppm Mg and 15.86ppm Ca, and 30ppm K (not including the K in the booster). The problem I believe is the iron content, and adding 30grams of this adds a lot of iron to my tank and so the green hair algae comes.
I dont feel the stunting issues has anything to do with the potassium or the nitrates.
Thanks very much for all your help
