I think your rock is loaded from the die off when your tank crashed.

if you can borrow a skimmer put that on there , I have two on my tank and it seems to be getting rid of it, I added more powerheads first but only knocked it out right where the water was flowing so that's when I went to a second skimmer three days now and its falling back. I couldn't quit feeding my tank wife's fish and all, if your tank recently crashed the die off is probably what's feeding anyways,

I do believe it is probably from the rock.

My salt meter is th elittle plastic one with the arrow in the middle. I have had it for years and constantly check mine with my LFS when i get a new fish. It is always dead on to what it is suppose to be.

So my skimmer, i have a tunze, should i crank it up where it produces very liquidty, clearer junk. I havealwasy had it set where it was a darker, thicker material.

Make it more liquid at least for now. You want to get the stuff out of the tank.

I am not sure on the tunze - I would think more fine bubbles would be better.

> My salt meter is the little plastic one with the arrow in the middle.

this little device is what i just replaced. i had mine for years.
maybe it works fine for 1.023 in a generic way but let me tell
you i was shocked how far mine was off when compared to a
digital salinity tester or a quality refractometer.

you could very well have 1.029 when your plastic device says 1.024.
you could very well have 1.035 when your plastic device says 1.026.

all i am saying, is that that tool gives you a generic idea of how much
salt is in the water and the tool does not improve with age. its accuracy
should be considered very poor!

maybe i was the exception... but i was disgusted how far i was off using
that little tool when i got my pinpoint digital monitor for salinity.

can you take your water to the fish store to be tested by them?
i am just trying to help. i may be way off.

>It is always dead on to what it is suppose to be.

i think its accuracy is poor and will give you 1.023 when the water
is in a range of 1.021-1.026. if you actually try to use it to measure
1.026 like many wish their water to be around here... good luck to u!

I doubt the salinity has anything to do with the algae.

I use a refractometer to measure the salinity.

Algae needs food and light to grow. Usually from excess nutrients in the water or rocks. Cyano is more of a bacteria IIRC. Syphoning it and more flow has worked for me in the past along with increased water changes.

i use pinpoint's digital salinity monitor.
i calibrate it with a solution that costs a buck or two
every once in a while.

i had an algae problem due to high salt. my two cents.
