Need help with low ph and low alk

Current levels:

Alk: 5
PH: 7.8

Some algae has been growing and some of my zoas arent looking pretty.

Whats the easiest way to raise alk and ph?.. and instructions would be helpful too.

I have a 37g tank w/ 10g sump.

 

anyone... please..... help

 

Do you have a buffer?

Try a water change.

 

By buffer.. you mean like 2 part or soda ash?

 

I have soda ash and the rest of BRS 2 part. I might do like a 20 g water change tomorrow.

 

okay I think I might buy seachem reef buffer and reef builder. I have a lot of sps and corals for a 40g tank.

My current levels, again, are:
Alk: 5
PH: 7.8

After reading I think that I should start off using the buffer.. because my ph is a little low and my alk is really low.

Should I just start off with the recommended 1tsp and use the water bottle drip method?

Or.. should I start lower than normal?

I also plan on doing a pretty big water change.. about 15 gallons. Should I do the change.. then test.. and then dose if necessary (after the water change)?

Or

Should I dose first. than wait. then water change if needed?

Or would either way be fine hahaha. Anyway srry for all the questions.. I just am worried about my tanks levels, so any help is greatly appreciated.

I tried to bold things to make it easier to read btw.. haha not sure if it worked.

Please help me out.

 

get a bottle of 8.2 at the pet store

 

So.. I guess its pretty bad when I comment more on my own thread than other people...

 

go to the fish store and look for this it will resolve both those issues follow the directions on the bottle http://www.seachem.com/Products/product_pages/MarineBuffer.html
but it sounds like you need to start dosing a two part or look into kalk.

 

Personally I'd go with a two part like ESV. I've been using it for 6 months now and my ca/alk have never been more stable.
