Newbie in need of advice

[LadyV]

Hey all, Teresa here, I'm new to the reefkeeping scene and am in need of some pointers, advice, otherwise known as HELP. Started up my aquarium in Jan (great Christmas gift) and truthfully I am having a blast. I love this hobby. I'm a retired RN by trade and so a lil obsessive about cleanliness in my tank. Things have been going great thus far and I have learned a lot by reading and researching. My tank has been going through all the normal stuff a beginner tank goes thru to include the dreaded Cyanobacteria stage. In fact I've been dealing with this bugger since mid June. I've treated with Chemiclean 5x so far. The first time was great, every subsequent treatment seemed to be less effective. The last treatment nothing....now mind you I have folowed the directions to the letter has advised by all so I don't think that is the issue. At this point the only thing I can find is maybe I'm doing too much treatment and massive water changes. My water parameters have always been really good for a beginner tank. I'm at a loss, what is the problem and why the cyano won't move on. Oh yeah feeding is one my sis cube daily with spirulina pellets

What's the TDS of water being made?

Thanks for asking. I forgot to mention I make my own water using the BRS 6stage RO/DI and HW Marine Salt.

Hi and welcome
I think what you have done is rid your tank of any cyano that chemclean kills. You now have a chemclean resistant strain. You have also killed off any organisms that would compete with the cyano for nutrients. Normally it goes away on its own when other algaes take over. I would stop adding chemicals. I notice your po4 is 0. Things need it to grow. I would stop with the GFO or reduce the amount in the reactor and see if the po4 goes up. If you have some way of growing a macro algae like chaeto in the sump or fuge. This would compete for nutrients and maybe your cyano will go away. In the mean time siphoning it out when doing water changes is what I would do.

Stop chemiclean.. Stop GFO... Stop obsessive cleaning.
Siphon out as much of the cyano as you can with water changes (20% every 2 weeks)..
Turn lights off for 3 days at a time every other week..

Let tank recover from the over treatment..

Agree stop chemi clean, will get rid of the problem temporarily but if you don’t get to the real problem it will be a bandaid fix great advice Mcgyvr

When I have done
3 day lights out I actually go black out and wrap the tank to shield all light.

Nothing suffers and the Cyano is gone.
