0:22
green growths that can quickly take over
0:25
a pond they thrive in nutrient Rich
0:27
water with plenty of sunlight while some
0:30
algae are beneficial for a pond
0:32
ecosystem excessive growth can deete
0:34
oxygen levels and make it difficult for
0:36
koi to swim before we dive into removal
0:39
methods it's important to understand
0:41
what causes string algae to flourish the
0:43
main culprits are excess nutrients
0:46
particularly phosphates and nitrates
0:48
combined with ample sunlight these
0:49
nutrients often come from overfeeding
0:51
fish decaying plant matter or run off
0:54
from surrounding areas now let's look at
0:56
some manual removal methods the simp
0:59
simp L approach is using a pond rake or
1:02
algae brush to physically remove the
1:04
algae gently twirl the rake or brush to
1:07
collect the stringy growths then remove
1:09
them from the pond be careful not to
1:11
disturb the pond bottom too much as this
1:14
can stir up sediment and release more
1:16
nutrients another manual method is using

designed for coons can be effective but
1:39
use them with caution always follow the
1:42
manufacturer's instructions and be aware
1:44
that dying algae can reduce oxygen
1:46
levels in the water it's often best to
1:49
remove as much algae manually before
1:51
applying chemicals hydrogen peroxide is
1:54
a natural alternative that can be used
1:57
in small doses it breaks down into water

algae need to grow buff clarifiers Can
2:37
Be an Effective tool in preventing algae
2:40
growth these devices use ultraviolet
2:42
light to kill single cell algae before
