I have a 20g Nuvo fusion QT that is cycled. Added 2 small fish about 5 days ago - Purple firefish and tank bred Rainford's goby. Rear sump : both overflow ends use IM aqua gadget custom caddy with floss plus 2 cubes of Marine pure in another chamber. When I got the fish I added some ATM colony and an an 11oz. bag of Chemi-Pure Blue. B4 adding chemipure : pH = 8.09 ( Pinpoint monitor with probe calibrted) ; 0 NH3 , NO2 = 2ppm; NO3 = 25ppm. Day after i added fish & chemipure I tested water and no NH3 but NO2 went to 10ppm ( Hanna Checker) and NO3 went to 50-60ppm ( Nyos test kit), plus pH went down to 7.55! . On 11/30 took out chemipure and added Poly Filter cut out to fit each custom caddy, also 40% WC; 12/1 = 30% WC ; 12/2 = 30% WC. Last night checked NO2 = 10ppm (Hanna C.) and NO3 = 60ppm (Nyos). Today haven't checked parameters yet but looked at poly Filter pads and still white. I assume after 3 days they would have turned color if NO2 & NO3 were elavated. Fish appear to be doing fine, both appear to be eating - small amt. of flakes in am & some Hikari Omega-3 enriched brine shrimp in PM , remove any uneaten food after a few minutes and return pump off when feeding. Saltwater mix - Fritz Pro Reef to S.G. = 1.025. Also when mixed Alk showed 9 ( in Mixing container) after testing the QT alk on 12/1 it showed 7.6 ( Hanna checker). As of now Ph showing 7.81.
Don't understand whats going on. Can Chemi-pure blue cause NO2 & NO3 to spike, pH & alk to decrease? It's got to be the test kits? Have Lamotte Alk kit , Red Sea NO3 test kit and Salifert NO2 kit coming tomorrow for backup. Any comments appreciated!
