Hi!
I've had afew threads about my cyano situation / tank not doing well. Since the tank overall is doing alot better but still cant rid the cyano. Had cyano for about 4 years, green and red and between two tanks (same livestock and rock pretty much). Always had low but measurable nutrients so i figured the cyano took away abit of it. Until recently.
Tested alot of thinks with a reasonable space inbetween with various results but nothing seems enough.
System
Red sea reefer 625 xxl with a fragtank at 180L plummed into the same sump. The system is pretty stocked fishwise with 5 medium tangs and 1 small, 1 copperbanded butterfly mediumsized, 2 clowns, 2 wrasses, 1 hawkfisk and 1 dragonette. Coral wise i got quite alot of corals and frags but im currently batteling AEFW aswell (winning tho). Some meaty LPS. Corals are pretty bland in color. While i can understand that the acros are ticked of the LPS isnt to colorfull or happy either. Nothing dying, just not to their full potential, color and lush wise.
Flow
Display has 4 MP40QD, 2 running 100% reefcrest and 2 at 40% pulse. I've configured it so that it helps to drive detritus to the sump which seems pretty successful.
The fragtank has two small tunze 6015 (1800 LPH) and a jebao sw 10 running some random program (8000 LPH) The flow is pretty over the top for the 180L tank from the looks of it.
Filtration
I started out with a skimmer and a clarisea SK5000 along with some ceramic media (maxspect bioblock x2) and have since upped the filtration. Reason behind it was that my phosphate started to creep up (will be more detailed from ICP later in the post). I did a ICP and got the results 02/27/2021 and got all greens besides phosphate. It was at 0.113. Nothing to major in my opinion as a 3 time dino survivor. So i started a fuge which grows chaeto greatly. I figured i should keep my nitrates up aswell since the refugium would consume it so i started dosing KNO3 alongside. I wanted to get the no3 up abit since it was about ~2ish when i started the fuge and i have since dialed it in to a consistent 8 ppm no3.
Over the course of about 5 months i got no results from this and got frustrated and sent another ICP test and got it back 08/27/2021 and once again all good except phosphates. They were at 0.159 mg/l. I got feed up after all these years and ran 1 dose of chemiclean which cleared it right up. Took a couple of weeks then i got some small patches of hairalgae. Mainly in the fragtank.
To get the PO4 down abit since my target is 0.05 - 0.1 i started a reactor with AL99 from triton. first at 3/5 strength, next reactor 4/5 and lastly 5/5. The media is changed every 3 weeks since im guessing it gets depleted quite rapidly.
After about 1.5 months the cyano came back with a vengence. This happened while the reactor with 4/5 strenght was running. I has gotten worse over time since and here i am.
Lighting
Display is running 3x radion xr30w pro gen 3 and the WWC program at 70% giving me 350 - 250 par at the rockwork and 100-200 at the bottom. Fragtank is running a simularprogram on it with the same par numbers averaging par at 200-300 on the eggcrate.
Maintainance
10% weekly waterchange Red sea blue bucket. Mediachanges monthly and detritus/cyano removal at WC weekly. I also blow over rocks with a turkeybaster at WC. I trim the chaeto once every 2 weeks and when i do i remove half.
Feeding is frozen daily. I've reduced it to half of what i previously did which was about 2.5 cubes of mysis daily to abit over 1 cube. I occationally throw in 10-15 pellets (every other day or so).
Suppliments dosed are red sea colors 1 ml / day and 20 ml of KNO3 giving 0.5 ppm / 100L
Water source is my own RODI with 0 TDS and i have filter / silicate media change on 3 months alerted by my apex, carbon filter 6 months and membrain 1 year.
Parameters
Ca: 420 on avarage - (410 - 440) (red sea ca pro)
Mg: 1360 (1280 - 1400) (red sea mg pro)
Kh: 7.9 - 8.3 (alkatronic and salifert) - Daily swing about 0.3 Dkh.
No3: 8 ppm since i started dosing in july, 2-4 ppm before that.
Po4: I dont know really. My red sea po4 pro test kit seems to be way of. When i tested the same time as ICP1 i got 0.04 ppm PO4 and triton gave me 0.113 mg/L. ICP2 0.08 and triton 0.159 mg. Making it consistant and 0.7~ off.
Things i've tried in the past
* Dosing various bacterias
* Increase NO3 by dosing (like 2 years ago or some but stopped at some point)
* Less and more feeding (over the course of months)
* Aggressive detritus removal
* Removed sand about 3 years ago and have been BB since.
I cant really thing about more stuff. I know theres alot of info about the system and what i've done. Most things have been tried over the course of weeks to months before evaluating so there's no point in saying "wooha buddy thats alot of changes" I try to be patient and change one thing at a time and give it atleast 4 weeks before doing anything else.
Hope someone on here can spare the time and help me come to a reasonable solution and find the fundemental problem causing the cyano.
While the phosphates were/are high i know they contribute but i dont wanto slam them in the bottom since I have a great feqr of dino. It has wiped out my tank 3 times the last 10 years and i dont wanto go down that road again.
Both ICP are attatched
