Fill out the 'soilless' troubleshooting form (in the sticky at the top of this forum), and copy and paste it here. Some pics would also help.

17) What is your ingoing water's ph? ...your runoff ph? not tested

What stick? No ppm/ec meter?

Should test the ph once everything's mixed, or is it tinted so you can't use your strips?

its a stick that show you the food strengh and i also have a novice ph tester, ph is around 6.2.
i test the ph once the food is added and also leave it over night to settle before i do any testing, what would happen if my water was to warm??
it was at 90 farenheit but now i have set it to 70 farenheit, i feed them every 2 days and there in cocoa

You could lower the PH just a tad. But your issue is the excess heat. 90deg water holds FAR less oxygen then 70deg. So that was likely your biggest issue.

[johnboy198]

what should the temp of my water be and also i want to post a pic but dont know how to?? anyone willing to talk to through it

[Vancefish]

If you take pics with a phone, email them to yourself. If it's with a camera, transfer to your computer.

Then when you post a reply, there is paperclip symbol just right of the fonts, size and color tabs. Almost top dead center of the box you write in. Click that paperclip, then pic one of the five slots in the pop up. Click browse and find the pic in your computer folders. Once the pic chosen click upload.

Personally I'm not sure what temp is optimum. However I've seen many people say 68-72 ish. I could be wrong though. I just know 90 is way to high.

heres a pic let me know the out come

[johnboy198]

how often should i be watering them and will all the oxygen be gone out of my water tank now or will it be ok
