I would do 50% water change daily until ammonia hits zero. From there I would test daily and do 25-50% change any time you see any ammonia show up at all. Hopefully eventually it will stay at 0. At some point, with all that ammonia, you're likely to also get nitrites start showing up. So I'd be testing that as well and changing water when you see signs of it too.
You must have had a lot of your bb in your gravel.. can I ask what filter you're using?
As long as he's eating and breathing normally and not acting stressed I would say just keeping on top of his water would be all he needs. You could put a touch of epsoms at around 1/4-1/2 tsp per gallon predissolved if you want as they can help with ammonia poising. Needs to be 100% pure magnesium sulfate. They also have some mild antifungal properties in case there's something going on. Predissolve it in a cup and add it slowly over an hour as it might cause a ph shift. Your plants will like it too. It's a fertilizer for them. When you don't want him in the ES anymore just stop adding it during water changes (won't ever evaporate or break down so no need to redose until you do a water change).
Also using prime as your conditioner (or AmQuel Plus) during cycling can help render some of that ammonia non toxic and help your bioload break it down faster.
The tank is still recovering from an algae outbreak a few weeks ago; the amount present now is about 20% of what it used to be
I have black sand now, but the black beard algae has pretty much disappeared now.
The filter is the Marina S10 (http://www.amazon.com/gp/product/B00...ls_o01_s00_i00
) with year old media from my other filter (should have BB in it).
I'll keep up with those water changes daily then until I notice a pure yellow on the test and some nitrates. Unfortunately, I don't have any epsom salts with me now, but I should be able to get some this weekend.
Thanks for the information, I'll keep you all posted!
