Raising pH to fast dosing alk??

I was just wondering if I raise my pH to high or to fast with dosing. I dose at night prior to going to bed. Before dosing my pH is around 8.1 and after dosing 8.6. My morning around 8.1 again.

1) Is 8.6 to high where it is stressing corals/fish?
2) is a rise of .5 to big a pH swing where it will stress corals/fish?

 

Rapid pH swings are never ideal, but do things look fine?

What's your alk. at each day? Large coral load?

 

I'd recommend dripping your dose over the course of the night.

 

Yea I hate raising the pH like that but if I dont dose my Alk and pH will swing down. Trying to get a dosing schedule dialed in but its proving to be difficult to find the right spot. My Alk with dosing is around 8-9, if I miss a few days it drops to 7. I have a decent coral load but think its my crazy coralline growth that is actually consuming the majority of my alk and ca.

 

If I dripped it over the course of the night how would I dose the CA and Alk 12 hours apart? Also what kind of doser would I use I am measuring and pouring by hand at the moment, CA in the morning after I wake up and Alk at night before bed.

 

You'd have to rig up a contraption using something like an AccuDrip and put it in a cup of the solution higher than your tank and have it drip at a constant rate. That's the cheap route.

The expensive one is to get a standalone dosing pump or get something like an apex to control a BRS doser.

 

Where's your mag. at? I wonder if what you're adding is just precipitating out.

 

You can't miss a few days. It has to be done consistently, every day. If you can't keep on schedule, look into dosing pumps or a Ca reactor. Your pH will change from day to night, so a .5 change would be normal.

 

mag is 1400-1500 with Red Sea Pro and Salifert so no issues there. I dontthink it is jsut precipitating out because when I add it if I test shortly after it does go up as expected and then drops pretty quickly within a couple days of not dosing. Thats when I started daily dosing, pretty sure my corals and algae are jsut using a crapload of Alk and CA.

 

I do dose daily now, didnt always need too but somehow ended up at this point. I am not looking for a CA reactor but and now nothing of dosing pumps any ones you can suggest would make my life a ton easier!! I know a .5 over the course of a day isnt bad but over the course of a few minutes is it too much and is 8.6 too high?
