Update:
Recieved my order from Marinedepot (love them!). Dosed 13 cap fulls of the Paraguard last night. Chose Paraguard as it seems to be all purpose and most importantly somewhat reef safe for entire tank. I would like to remove both eye problem and possible eggs in tank. Removed skimmer collection cups, but left skimmer on for oxigen exchange (skimmer cups removed so I don't remove Parguard from tank).
Noticed the water did not change color.
The Aiptasia (I really have a non-stop aiptasia problem) all shrinked and looked like they were disentegrating within 15 mins of dose (added benefit!). Half Xenia shriveled up, other half is fine.
No fish stress, blue legged crabs still alive.
So this morning I dosed about 7 caps fulls as instructions state keep dosing if fish not stressed daily.
Note:
130g total volume in tank
So far so good, let's see if the Blueface eye problem clears up.
Will post follow-up in a few days. Will most likely not change water out for 30 days to ensure I get rid of any potential eggs.
Also chose whole tank dose as I dread taking out 200lb of live rock and losing my aquascape which took me hours to achieve, just to catch the Blueface, also I am pretty certain that my problem is either flukes or fungus, thus treating whole tank is in order now. I'm willing to take the risks involved.
