Phols extra special and AcroPower

[charterreefer]

Does anyone have experience with using Pohls extra special? Is it worth the price? How about Sprungs AcroPower? Is this the best amino acid out there? It is so much cheaper then the Korallen products. I was using Fuel. I think it helped a bit but have nothing to compare it with.
I have a ULN system.

I try not to run an ULNS system so can't really answer your question. I do dose acro power very occasionally. It helps with PE a little.

I use Pohls Xtra not the special and also Acro Power. It does help with coloration IMHO. I do not have any zeovit reactor. I just dose them right into the tank.
