I guess my question is, what brand do i get for a dechlorinator
That should depend upon what you need for your tap water. If you have chlorine, and/or chloramine, most conditioners will detoxify these, it will say on the label. Many also detoxify heavy metals. I would not go beyond this, unless you need to, by which I mean, if you have ammonia, nitrite or nitrate in your tap water, then a conditioner that deals with these (whichever) is advisable. But only if these are present in the tap water. To explain why, I will harken back to what other members have said about not adding medications, chemicals, etc when not needed.
Freshwater fish continually take in water by osmosis through their cells. This is their equivalent of our drinking, except for fish it is a continual process 24/7. Anything and everything added to the water is thus getting inside the fish, in its bloodstream and internal organs. As well as this, there is the gill process during which substances in the water can be transmitted into the bloodstream and some can harm the gills. Every additive and substance is adding more dissolved solids to the water, and these obviously get inside the fish. All of this can have a very serious detrimental effect on fish.
Increase your water changes to at least once a week (once weekly should be adequate, assuming the tank is biologically balanced, not overstocked, not being overfed, etc.). The more water you change, the better. I would suggest no less than 30%, but 50% is going to do more good and may be necessary, again depending upon the tank size, fish load, species, foods, etc. Vacuum the substrate in the open areas, though this too can vary. And rinse out the filters regularly, again depending upon the tank/fish and filter.
Back to the conditioner...once you have determined what you need, most any brand that provides those will work fine. If you want to ensure cost efficiency, calculate the amount of conditioner needed against the price; some like the API that may seem expensive are actually extremely inexpensive, as they are highly concentrated and you use very little. And here again, the less "stuff" entering the water, including conditioners, the better the fish will be.
This is echoing others, but never add medications or treatments for disease to an aquarium with live fish unless it is absolutely necessary for a specific health issue. Never use algicides or chemicals that kill snails. Plant fertilizers are fine if they are needed, but do not overdose.
