Seachem Prime Concentrated Conditioner, 500 ml vs AQUARIAN Tap Water Safe Fish Aquarium: Which Should You Buy?
Two tap-water conditioners for fish tanks, but one treats vastly more water per pound.
Here is a genuine like-for-like, and the sticker price misleads. Seachem Prime costs £18.66 for 500ml, but it's heavily concentrated, just 5ml treats 250 litres, and it also cuts nitrates and ammonia. AQUARIAN's £2.65 buys 118ml that instantly dechlorinates tap water, simpler and cheaper to pick up. On rating, Seachem leads 4.8 to 4.6 with far more reviews, 37,000 against 14,000. Neither lists offsite scores. Work out cost per litre treated and Seachem is the runaway value for regular water changes; AQUARIAN suits a small tank or occasional top-up.
