Hi all, it's been a few weeks, but I have been battling what I believe to be cyano
. I siphon it out with water changes and suck it up with a turkey baster and it's back within 24 hours.
I switched the lights off yesterday so they wouldn't go on when the timer said "go" and came home for lunch and it was actually worse than when the lights are on! I can't figure it out. It's done the same thing when the lights are out for longer than the normal time. My lights are on for 9 hours a day with 2 10,000K and 2 actinic blues.
The stringy stuff started out only on the sand, but overnight it has spread to my rocks.
The color of it is blue-green on the right side of my tank, and more of a dark red on the left side. I have 2 Koralia 750 gph
powerheads on opposite sides of the tank. Flow isn't the issue because the strings are constantly "blowing" around in the water, and I can't find any dead spots.
I've also severely cut back on my feedings the past few weeks. Once every 2 or 3 days, and only what they eat in a minute with no food touching the sand.
Also running an eshopps psk 150 protein skimmer. My tank is 75 gallons with a 20L gallon sump. I've also got a small ball of chaeto in the sump as well.
I've done everything I have read to do in battling this stuff, but it's stubborn, and I really don't want to use any type of chemicals to get rid of it.
Oh - almost forgot - my tank is filled with RO
water, with water changes and top off being RO
as well. The unit is about 2-3 months old, and the first pre-filter is still as white as it was the day I got it. The DI
resin is the copper color and hasn't turned black yet either.
Long winded post, I know. Thanks to those of you who read it all!
