ElevateShrimp Posted August 20, 2015 Report Share Posted August 20, 2015 Hey has anyone ever measured oxygen in water? I've had a few crs die recently and I'm thinking it might be a lack of oxygen. No air pumps going into the tank. water params: ammo/nitrite: 0 nitrate: 7 ppm temp: 71-72F pH: 6 GH: 5 KH:0 RO/DI with 0tds remineralized with blue wizard 1.5mL per 4 gallons Quote Link to comment Share on other sites More sharing options...
JamesHe Posted August 20, 2015 Report Share Posted August 20, 2015 Yes, just quite expensive. Couple hundreds dollars. Quote Link to comment Share on other sites More sharing options...

Do you usually find the carcass in the morning or throughout the day? Quote Link to comment Share on other sites More sharing options...
ElevateShrimp Posted August 25, 2015 Author Report Share Posted August 25, 2015 I threw in a sponge filter and left everything else the same, I will see if there are any more deaths and then rule out oxygen If your shrimp dies because of lack of oxygen, you should see them either climbing to the highest point of the tank or keep swimming to the top and fall down to the substrate.Do you usually find the carcass in the morning or throughout the day? I'll find them throughout the day, tank is lightly planted with mainly java fern types. Quote Link to comment Share on other sites More sharing options...
Shrimpy Daddy Posted August 25, 2015 Report Share Posted August 25, 2015 Usually oxygen problem is elevated at night. Quote Link to comment Share on other sites More sharing options...
35ppt Posted August 25, 2015 Report Share Posted August 25, 2015 what about the nitrates @ 7ppm? Quote Link to comment Share on other sites More sharing options...
DETAquarium Posted August 25, 2015 Report Share Posted August 25, 2015 I wouldn't be concerned with Nitrates at 7ppm, until recently my TB tank had nitrates of 10-15ppm and they constantly bred, and 90% of shrimplets have been surviving.

Shrimpy Daddy Posted August 25, 2015 Report Share Posted August 25, 2015 what about the nitrates @ 7ppm? All my tanks, I maintain NO3 at minimum 10ppm. Quote Link to comment Share on other sites More sharing options...
