Need some advice... Tank not doing well.

[Oxymoron]

The recovery,
I took a toothbrush and spent about 6 hours scrubbing the rocks, glass etc.
The process released massive amounts of crap into the water
My strategy at first was to stir a bunch of the larger particles up and catch them with a net. This worked well at first as the entire tank was literally covered in hair algae and patches of cyano.
Eventually I came up with an idea to try taking a sock and tying it on the end of a powerhead with an elastic band. (I didn't have any filter socks when I came up with it lol.)
To my surprise this worked beautifully.




I spent several more hours scrubbing rocks and blowing detrius into the mini vacuum.
25 gal water change and a fresh batch of rowaphos and carbon.
I have another 25 gals being made up atm and will do another change on sunday.
Here are some pics of where I am at now.






Sry pics are from iphone.
Appreciate everyone's suggestions and help.
A blenny and some turbos are my next step.
Ill update with my progress in about a week.
