Amino acids can be considered as chains Inverts use this chain as a way to build their structure

for inverts, they either take small chain link or each small loop of a chain to build a long chain
or they take the whole chain immediately
So how do they decide, what to do?
It all fall down to the type of Invert, so different Invertebrates have different nutritional demands
In general Stoney / calcium building (Small polyp) take individual loops due to the size of their mouth
Fleshy Invery or (Large polyp) or softies, because of their larger mouth take in the whole chain.
Amino is more of a bottle of these free floating loops also known as free-form amino
 
restore is a mixture of both free-floating loops and complex chains
restore was developed so that if you wanted a mixture of both forms of amino acids you have a bottle which has both forms which will be useful for your Inverts
so if you have an sps dominant tank then go with BW Amino if you have a mixed tank then go with restore it is as simple as that
If I use restore what happens to my sps will they get nutrition?
well you don't have to worry about that because restore in this bottle also has free-form amino coupled with complex chains

Widely used by professional coral farmers to increase tissue growth rate
Provides important nutrients to corals and their allies during periods of stress-induced by changes in lighting and/or prolonged exposure to excessive water temperature (often resulting in “bleaching”).
Aids in tissue repair after corals have undergone fragmenting and captive propagation.
Restōr does not require refrigeration, however, storage in a cool, shaded area will prolong the activity of the vitamins. Refrigeration will maximize the shelf-life of the product.

Instructions and Guidelines
Shake product well before using. Turn protein skimmer and other forms of mechanical filtration off prior to adding foods fortified with Restōr to aquaria, and allow 10 - 15 minutes after feeding before resuming operation of filtration.
Target Feeding (recommended): Target feeding may be carried out with a lengthy piece of rigid air tubing, plastic syringe, pipette, dropper, or similar device; pour 5 ml (1 capful) into a small container and suck a portion of this into the feeding device, then slowly discharge the contents of the device 2 - 4” upstream of the target organism(s). Repeat these steps as deemed necessary. Wash the portion (inside and outside) of the feeder that was placed into aquarium water with a dishwasher or very hot water and soap before placing it into this bottle (if feeding directly from the bottle rather than from a separate container); failure to do so will contaminate the product and encourage it to decompose. Restōr may be utilized as a food-soak; to do so, place food into a clean container, add up to 5 ml of Restōr and allow 5 - 10 minutes for food to soak; target feed as directed.
Broadcast Dispersal: Add up to 5 ml per 50 gallons of water in the entire aquarium system in an area of rapid water movement every two to three days for the first four weeks of use; thereafter, the dosage may be increased as desired.
Notes: Add no more than 5 ml total of liquid food suspensions per 50 gallons of water in the entire aquarium system daily for the first four weeks of use; thereafter, the dosage may be gradually increased as desired. Starting out at a low dosage and gradually increasing it with time will allow the biological filtration in the aquarium to adjust to the increase in nutrients and prevent water quality from deteriorating.
