Can't get good alkalinity levels

Hi,

I´ve been fighting hair algae for a year. I tried everything, then i
found my KH was too low (4,5 dkh) and calcium too high (550).
I tried to put things right. So i stopped adding kalk and started
dosing Seachem's Reefbuilder.
I had to dose lots of this product to reach 8 dkh, but, when i stopped
dosing it just for one day, dkh fell around 1 or 2 dkh.
Then I realised calcium fell to 280, so i restarted dosing kalk
through my kalkwasser reactor.

Now calcium levels are fine at 420 and i still can't get my alkalinity
higher than 7,5 dkh. I stopped dosing Reefbuilder and i am now dosing
C-Balance:
30 ml part A daily
60 ml part B daily (I want to get my alkalinity to 10 dkh and mantain
my calcium levels)

I have tried water changes and didn't solve the problem. KH isn't
getting higher.

By the way, i have a Deltec Fluidised Calcium Reactor (PF600). It's
outputs a 40 dkh and a ph lower than 7,5. This calcium reactor
doesn't seem to help

Hair algae persists. What should i do? Add more part B of C-Balance?

My tank is 180 gallon with mixed SPS and soft corals. 4 small fish.
DSB and lots of live rock.
Some coraline algae grows behind the rocks.
I have a huge efficient skimmer (Aqua-Medic Turboflotor 5000 Multi).

Than you for your help,

Hi Reefman,

Have you read this page yet?

You have a Calcium Reactor and a Kalk Reactor going to your 180g, and you are
still dosing C-Balance? I would think at that point you wouldn't need a 2-part
additive.

KH was too low and calcium too high

Read this to solve this problem...

Hair Algae will due to either...
High Nitrates
High Phosphates
Old or Incorrect Colour Freq Lamps

Try using a macro algae {seaweed} to out grow the hair algae...
Rowaphos to absorb the phosphates and check the age of your lamps...

Hi, Marc,

Have you read this page yet?

Yes i've read it and tried everything during a full year, except
rising my alkalinity. If i could get 10 dkh and stay with it for maybe
a month, i'm sure i'll get rid of the algae.

You have a Calcium Reactor and a Kalk Reactor going to your 180g, and you are
still dosing C-Balance? I would think at that point you wouldn't need a 2-part
additive.

That's what I thought when I bought the calcium reactor about 5 months
ago!
Then about 2 weeks ago I started adding C-Balance.
The reactor is working like the manufacturer instructions. According
to Deltec, my calcium reactor is suitable for 355 gal. aquariums with
heavy stocking and high illumination
(http://www.deltecaquariumsolutions.c...reactors_3.php).

Any ideas?

Reefman,

I'm thinking Boomer would have some ideas what could be draining that much
Alk out that fast. Maybe there is a heavy weight on the end of the Alk
balance pole... Sounds awful whatever it is.

if your reactor is adjusted correctly then your ballance should be
consistant and not be dropping on either Alk or Ca.

have you double checked your test kit? just a thought on that.

also doing a large water change might help get it back in ballance and then
make it easier to keep there. adding the c-ballance is most likely just
hindering your progress and unballancing your system IMO.

I have always used Hagen's Test Kit Carbonate and Total Hardness
(KH/GH) - (http://www.hagen.com/usa/aquatic/pro...07830002010 1)
I buy lots of this test kits.

Over the last months i've done lots of water changes. Last week i did
2 WCs (18% each one).

My best suggestion then would be to readjust your Ca reactor.

its best to do daily testing of Alk and keep upping your CO2 until you don't
get a decline in Alk from one day to the next. then test Ca, if its low
dose "turbo Ca" to bring it up to the desired levels. recheck your Alk when
you get Ca correct and make sure you don't need to fine tune the reactor.
if your system is balanced then the reactor should keep both Alk and Ca at a
constant level at this point. this can take a week or two to get in
adjustment. it takes patients and its best to write the test results down
daily for a log to look at. it's well worth the effort in the end.

I think that 7.5 dKH is plenty high enough. You are trying to chase
numbers that aren't necessarily realistic.

You won't necessarily be able to resolve a hair algae problem by
only working on calcium and alkalinity numbers. Adequate calcium
and alkalinity is a prerequisite for good coralline algae growth
in a system, but there are a number of other biological and
chemical issues at play here. You need appropriate herbivores
in the system, you generally need a good meiofauna population,
and you need to get a handle on any excess nutrients in the tank
before you will be able to resolve a nuisance algae issue.

that is true to a degree, but having higher levels of Alk and Ca help to
precipitate out PO4 and there by reduce the chances of nuisance algae's
using them as a food source.
