Help with tank

ibanezgfx · 02/14/2018, 10:10 AM

Hey guys,
I’ve had my 75g semi reef for about 8 years now. I added a sump a couple years back and have had some issues when filling forgetting about it and letting it over fill. By a lot. I’ve done it twice and the sg dropped to about 1.01 the first time, killed all my corals and I got a ton a hair algae.
About a year later I did it again. Now instead of hair algae I’ve got what looks like cyano.

Ph at 8.2
Ammonia looks low 0.25 ppm
Nitrates are about 10

My heater crapped out and it’s at about 68 f currently. Working on that one.

See below pics. Any advise??

Thanks.

Get to work.. plain and simple..
You need to spend a good chunk of time siphoning that crap out of the tank really well while performing extensive water changes..

Mcgyvr is right plain and simple, get to work. Siphoning, filter socking, water changing.
I have some bad ocd tendencies and like to keep algea out of site and things spotless. This tank kinda looks like a dream come true lol

You have multiple types of cyano, the brown hairy stuff on the rocks is too (Lyngbya spp). The Lyngbya and/or other growth will need to be scrubbed off.

As mcgyvr said, you will need to clean the sand and rocks manually, probably more than once, and also perform water changes as you go through the cleaning.

Get parameters right and stable, and give it TIME. I am healing a tank that actually had been left fallow and overgrown with Lyngbya, it takes time for rocks and everything to transition back and start growing other algae and coraline etc..]

ALSO, don't top off your tank directly from an RO/DI (guessing what you did)!

I would do large water change, scrub those rocks vacuum the sand bed and then do it over again. It going to take some work and time to get it back to normal

And how is your lights? Have bulbs been changed lately?
