So here's the story I had a amonia and nitrate spike a few days ago did a 20 gal water change in my 55 gal(had added snails and 5 macro algae plants) and dosed with prime levels went back down amonia 0 nitrate 10 2 days later just tested again now my levels are as follows ph down to 7.4 amonia up to .25-.5 not sure leaning to .25 but nitrite up to .5 never had it high before last test done it was 0 nitrate spiked back up to 40 do I do another water change and dose again or will it make it worse
