Please help me...

[Andreas' Reef]

I recently did a post earlier where I tried to discuss my algae problem. I was told it wasn’t that descriptive, which I understand. Anyway, my tank is about 6 months old, and I use Ro/DI water with fritz rpm. It’s a fluval evo 13.5 gallon. I want to have this be algae free. Here are my parameters.

Nitrate: 5 ppm

nitrite and ammonia: 0 ppm

Alkalinity: 210

Ph: 7.1

lighting period: around 9 hours.

here’s a picture... any help would be great.

Ugly stage. Just keep doing water changes siphoning out. Looks like u got no coral so just wait it out

I'd recheck your parameters: your alkalinity and pH are very much off and probably inaccurate.

It doesn't look like you have coral. I'd just turn off the lights for a week. You can have the moonlights on for a few hours each day.

I'd also aim your left return nozzle lower so you can get better tank circulation.

What was the question again?

I do not see any picture but your Ph is extemely low or an error in your testing i would guess. What test kits are you using? Do you have a clean up crew...snails and hermits? They will keep your algae in check if its not extremely long hair algae. If you have a pretty bad case of algae you would need to pull it out by hand to help get it started so the snails and hermits can do there job. Is your rodi water testing Zero TDS? Your alkalinity of 11.8 dkh seems on the high side.. Can you get your water tested at a LFS and compare yours with there results. You dont mention your salinity, temp, calcium.

When your water is correct, you'll get coralline algae, the pink/purple stuff, on the rocks that will inhibit green algae.

Typo: My ph is 8.1

I’ll redo a test on the alk and get back to you guys. I’m also going to try turning off my lights for Easter weekend.

some things I left out:

salinity: 1.024

temp: 77-78

Looks like green cyano so not actually algae(assuming i am correct).. If ph is 8.1 then alk and ph seem fine.

+1 that’s what it looks like to me.

I'm a big fan of a three day blackout solving a lot of problems or at least getting you headed in the right direction.

I disagree i think its a wasted unproven method that people keep promoting

Raise your salinty 1.026 gradually too low imo but some like it lower

Will it go away?

yep, as long as its been introduced into the system

everything goes away eventually

 

[dvgyfresh]

Looks like cyano like others have mentioned not actually algae, increase flow and do some water changes will help get in control

That’s sounded dark. Lol

get in there with a hose and suck out as much( maybe a gravel vac) as possible cut your light way back no reason even run if no fish. Check your water tds and dont add any no additives. Increase flow and mechanical filtration
