Nitrate high and Alkalinity low
Hi all, I cleaned my tank yesterday and stirred up the substrate more than normal. My nitrate is up a little and I'm about to travel for five days so I'm worried. I'll have someone house sitting but they know nothing about fish.
My water numbers are below with tank details.
48 gallon planted tank
HOB filter with filter floss and bioballs (no carbon)
Nitrate - 20 (usually 0)
Nitrite - 0
Chlorine - 0
Alkalinity - 75 (usually 120-140)
Ph - 6.9
5 neon tetra
3 glow skirt tetra
3 adult platty
2 sub-adult platty (7 months)
6 baby platty (3.5 months)
2 adult bristle nose plecos
Male maybe guarding another clutch of babies.
20 baby bristle nose plecos (3.5 months)
2 dwarf corey catfish
2 mystery snails
Tons of plants
Before cleaning the tank I removed and donated: 30 platty babies, 10 pleco babies, 2 adult platty.
Should I do a partial water change again tonight? Other suggestions?
We normally only rinse the filter floss every week and do a 15-25% water change every 3-4 weeks. We do not use charcoal or any chemicals other than Prime and a pinch of baking soda when adding new water. We add Stress coat anytime we introduce a new fish or if we have to net anyone.
