My ecoFinish feels like sand paper. Why do you think this happened?

I have a fiberglass pool that was coated
00:03
with eco finish over the course of a
00:07
couple of years especially this last
00:09
year I noticed that the surface of my
00:12
pool fiberglass coated with eco finish
00:14
after only three years feels like
00:17
sandpaper and we’re having a really hard
00:20
time getting what I assume is scaling
00:23
off of the surface do you have any
00:25
advice I think my first question and
00:29
that would be why is it scaling why is
00:34
calcium coming out of a solution and
00:36
attaching to the surface of the pool so
00:39
while one might suspect that the surface
00:43
is attracting these scaling my concern
00:48
would be is the pool pop properly
00:51
bounded bonded and grounded it almost
00:54
sounds like to me we have an
00:56
electrolysis thing happening in the pool
00:58
so while you’re having a difficulty
01:01
removing scale off of the surface of the
01:03
pool why is it getting there is the more
01:06
important question and what I would do
01:09
is I would go back through and make sure
01:11
anything and everything metal closed and
01:14
around the pool has been bonded I would
01:17
make sure that if you don’t have one now
01:18
it’s a salt pool I what I would do is I
01:22
would put sacrificial anode built into
01:26
the system one that plugs directly into
01:27
the system that has a bond wire attached
01:31
directly to the piece of zinc because
01:33
then that also will drain off any
01:35
potential low-voltage electrolysis
01:40
electricity in the water and what
01:42
happens specifically and we see this now
01:44
that so many pools are salt based is
01:48
pure water on its own does not transmit
01:52
electricity the metals and things that
01:54
get dissolved in the water are what
01:57
allow electricity to pass through the
01:59
water so when you’re taking a fairly
02:01
neutral water and you’re adding three
02:04
parts per million of salt you’ve now
02:07
made the ability for electricity to pass
02:10
through that water because it can jump
02:12
molecule to molecule
02:13
so it becomes all the more important to
02:16
be sure that you have no bonding issues
02:20
grounding issues because any trace
02:23
voltage coming from anywhere and
02:24
anywhere it could be leaked electrical
02:27
into the ground because our electrical
02:29
grid system leaks electricity all the
02:32
time it could be from any low voltage it
02:34
could be from the from cable wires and
02:36
Nick cable wire could be from any low
02:39
voltage speaker wires or anything in the
02:41
surrounding area or the surrounding
02:42
house those even teeny tiny voltages not
02:48
enough to hurt you or me
02:49
just trace voltages are enough to affect
02:53
the water and what happens is you get a
02:55
battery situation where you have
02:58
electrolysis and as that electricity is
03:01
passing through the water it’s dropping
03:03
the calcium out of solution and that
03:05
surface it’s adhering to the surface of
03:08
the pool so it’s kind of a weird
03:10
phenomenon we saw it in the past but not
03:13
nearly much as we see it now because of
03:16
the addition of salt and so many pools
03:18
are salt salt based chlorine systems
03:20
that we have to be really conscientious
03:24
on the building end to make sure that we
03:27
over bond the pool that every possible
03:30
place that we can hit we hit not the
03:32
minimum code and that’s that’s a big
03:34
thing that happens is everyone wants to
03:37
do the minimum code requirement and I
03:39
think now we have so many salt pools out
03:41
there fools need to be over bonded that
03:44
underbody
03:44
instead of hitting them in one or two
03:46
places out of the pool
03:47
hit them a dozen places on the pool or
03:49
there abouts because again we’ve we’ve
03:52
just created this this larger challenge
03:56
moving forward without sacrificial
03:58
anodes in way of ways of leaching off
04:00
that electricity if we’re not doing
04:02
those things we run the risk of damaging
04:04
surfaces and damaging equipment we’re
04:06
not going to damage human beings with it
04:07
because it’s it’s trace voltage stuff
04:10
we’re used to that all the time there’s
04:11
all kinds of things that we touch that
04:13
have 10 volts 12 volts 15 volts in them
04:16
all the time we get all that that kind
04:19
of stuff it’s high voltage that we have
04:21
physically have a problem with but low
04:23
voltage creates all kinds of issues with
04:24
equipment and
04:25
water more chemistry and what and Paul
04:27
finishes so just a little history in
04:30
terms of kind of what it could be I
04:31
would look at all of that before I even
04:34
worried about the finish of your pool I
04:36
would look at why is it happening
