Instant Amazon

Anybody here use Instant Amazon (Marc Weiss) before? I'm thinking about picking up a bottle, but I want to hear people's experiences before dropping the cash. I read bad stuff about Tetra's Blackwater Extract on the forums, so is the Instant Amazon product just as bad concerning PH swings?

FYI, my cycled 46 gal tank (did fishless for 2 months, currently at 0, 0, 20 nitrate, 7.5 PH) has no fish currently, but I was thinking about picking up some discus. I want to find the easiest way (would prefer not to filter over peat if possible) to create a safe environment for the fish.

Anybody have some input? Thanks.

Unless you are purchasing Wild caught discus the ph you posted is fine so long as it is not artifically achieved. Were it me i would opt for adult or sub adult fish. To achieve the best growth in juvenile discus requires four to five feedings a day which = frequent water changes (daily). Most grow out their juveniles in bare bottom tanks so that cleaning up uneaten food after these Feedings is easier. Adult or sub adult discus can get by with twice daily feedings. All discus benefit from water low in nitrates 10 or below is desired. Due to the frequent water changes products like blackwater extract or The product you describe would be expensive to constantly replace . I keep four discus in an 80 gal with two emperor 400,s for filtration, temp is constant 84 degrees, Ph is 7.4 from the tap. ammonia 0 nitrites 0 nitrates 5ppm. Water changes of 25 to 30 percent three to four times a week. Two of the fish are Adults and two are approx 4 in. I feed them all three times a day with a large variety of foods. If you can maintain stable water parameters your fish will do fine. I know of others who report keeping discus in Ph values of 7.5 to 7.8. Wild caught specimens or breeding require softer water which many achieve with reverse osmosis . Hope some of this helps you.

The most important medication in your fish medicine cabinet is.. Clean water.
