First, a shot of the Sherman. It's settled next to the "green" BTA that I bought a few months ago

, but looking happy and healthy.

Now, to the business. It's no secret that my frag system hasn't had the best run of things. It's coming up on almost two years of operation and equipment has come and gone, nutrients have ranged from zilch to almost zilch, almost everything and anything other than an outright crash has taken place.
For the last five or so weeks I've started making use of some products I've always had and just 'kinda dabbled with when remembering, and I think the results are starting to show. I'm sure that getting alkalintiy back in check and pretty well stable is also a large part to this, but I'm seeing revitalized growth and colour coming back to some SPS pieces that have done nothing for months or tens of months, even before the alkalinity issues had taken place this past summer.
Twice weekly there is 10ML of acropower, 1/2 TSP of reefroids and 20 or so drops of phytofeast being added to the tank. I've set the return to shut off for 30 minutes, the skimmer for 6 hours and let it blast around the tank as a particulate storm, hitting everything. Stagnant pieces are now showing highlights of growth, colour shading is returning, quite quickly in some cases. It doesn't look like much, but acros that looked like they got hit with an acid bath at least haven't died, and are recovering.

The bonsai frag plug that I pulled it off of 9 months ago has shown more growth in the last three weeks than those 30+ previous.

I can't remember what this is, but it was saved from STN and is gaining some orange / pink growth.

This hasn't had any growth in a year, to the point half of it had died and I threw it on there as a last attempt. The green is encrusting growth, which I haven't seen since it hit the tank.

This was eraser sized pieces of a 1.5" orange passion that survived RTN. That's on a frag tile that has not done anything for about 7 months, now it's encrusting very quickly.

The worst of my acros from the first alk crash this summer. It looked like someone dipped the small vibrant colony in a vat of acid, there was barely any skin pigment, no polyp extension, just a near-dead acro. Now it's gaining polyps, "skin", and the corallites are starting to gain fluoresce again. And it's encrusting, something that hasn't happened in almost a year as well.
