HELP NEEDED !

[MrDLHughesY]

Hi guys noobie here ive had my setup about 6 months now and think I am battling cyano please correct me if I’m wrong.

Just had a blackout stage of 3 days to try to get rid of it but has started coming back already.

PH 8.2
PHOS 0.03
NITRATE 10
CALCIUM 440
KH 8
SALINITY 1.25
Ammonia is showing 0.25 not sure if this could be the issue.

Any help would be appreciated

Tank volume and all livestock list? How often you change water? Do you have skimmer or Refugium. I would recommend adding a power head to have some flow at the bottom and control bioload, add skimmer/refugium . Keep feeding, as you want the beneficial bacteria to grow, don’t make tank very sterile. My learning has been these are chronic issues in the first couple of years, til, your rock, sand and water chemistry stabilize and the tanks own microbial population is stabilized. May be adding some beneficial bacteria will help. Last option is to remove sand.

Tank is a fluval sea evo 13.5g/52l
Fish-pair of clowns, damsel, Midas blenny and a yellow spot goby

Inverts- 4 nas, 1 cerith, strawberry conch,3 rock hermits, cleaner shrimp, tuxedo urchin

Weekly 20% water change

No skimmer/ref as read bot need on such a small tank with frequent w/c

Already have a wave maker at the back below the pump inlet.

Reduce water changes. Let the tanks own chemistry settle, reduce some clean up crew if possible, add skimmer to take out the protein , reduce photo period if possible and wait,,,

Water change like 20% every 2 weeks ? And thanks for you responses

two weeks sounds ok. Do you have chemical filtration in place?

Yeah I have the intank media box in chamber 1 with filter floss filter pad chemipure blue and bio rings

When I clean would you recommend to syphon the sand or just leave it be ?

looks like diatoms to me. Are you using RODI water?

Using pre mixed salt from LFS

Definitely siphon, but thats my vote. I went barebottom as i wanted sps in my nano.. so dont take my word as the best advice :-/ . Let other also express what they did. This is one of the three most common chronic problems in reef keeping, if you ask me. Diatom, cyano, algae(gha/bryopsis)..
How frequently you are changing the chemical filtration media? and how much?

 

[MrDLHughesY]

Seems to just get worse when I syphon my sand, I use two nano bags of chemipure blue and swap 1 over every 3 weeks and change filter floss every couple of days
