ive only used BIO-SPIRA when setting up my 75g for rays. I added water, started filter, added bio-spira to treat 110g of water, and added 3 giant danios, 3 rainbows and a gourami and xray tetra. (gourami and tetra were SUPPOSED to become ray food, but they apparently have different plans so far)
first few days tank showed i think 10ppm ammonia, some nitrates and like 180nitrite. however, tank was showing no ammonia, almost no nitrates, and around 80ppm nitrite after 7 days. added a stingray 2 weeks after starting tank, and dident have a single spike or issue thereafter.
now only 3 months after starting the tank, its stocked with 2 rays, a black ghost, yellow gourami, and a blood parrot. still always 0 ammonia, 0 nitrates and never higher than 80ppm nitrite still.
im sure people will disagree with bio-spira, but it worked well for me. despite the hefty price tag, i had absolutely no fish loss starting a tank for the first time. not even the little xray tetra. so the $ was worth not stressing my fish, and having a fully cycled tank.
