HELP! NastayNatron's tank

[christyf5]

Jeez, where in Calgary are you? Maybe one of your fellow calgarians can come over and assess the situation.

This is how I do water changes:

Turn off power heads.

Siphon desired amount of water out of display tank.

When sump starts to run very low or you see bubbles enter the display tank, turn off the return pump. Turning it off during siphoning prevents a flood in the sump.

Mix water to 1.025 mix using a salinity meter. Make sure water is at least room temperature or close to same temp as tank water.

Add prime to water if you are using tap water.

Slowly add water to sump and allow it to mix and come up to temp.

Turn on return pump and keep adding pre mixed water as needed.

Turn powerheads back on.

Since this is your first time I wouldn't do more than a 10% water change.

After 20 mins measure tank parameters again.

If you can get someone to help you do it, who has done it before, do a 20% water change.
