I've had good success in the past with Oceanic salt.

I am not cutting down salt lol what size of tank is it smaller tanks need surface agitation to release the c02 out of. The whater smaller tanks leess whater volume changes a lot easier and faster than lots of water I cured me problem switching to a hang on the back filter all I run is the aqua clear 70 on my. 30 run. The sponge and then just filter floss from a fabric shop. Gives you a break in the surface and crystal clear water

Some excellent info and resources provided above.

In my 10 years doing this low pH has never truely impacted my tank in a significant manner. As noted above, consistent pH is more important that pH level. I maintain a pH fluxuation of 0.1, again using some of the techniques noted above.

Maintaining consistent alkalinity is much more important than concerns regarding pH, again IME.

the tank is 120 gallon 100 or more pounds of live rock

how do you keep alk at the disired levels with good salt ?

[wickedfrags]

For a tank this size you could raise your alk with a commercial buffer/reef building product to the desired level. After this time, you will need to supplement your tank on a daily basis with a 2-part additive to maintain those levels (depending on the coral load of you tank you will need to supplement different amounts).

The other less time consuming method is to invest in a calcium reactor to maintain your levels alk and ca.

Agreed.

Weekly testing, and the use of a commercial buffer to raise it. If you're looking for a product name, one of my favourites is Seachem Reef Buffer 8.3 which helps keep a higher pH. If you have a fish only tank it isn't as important, but if you have corals you should try to keep your alkalinity within a 1 dKH (less than 20 ppm) swing, so this may require dosing more than once a week.

Agree with most of whats been said above,except for one thing....do not use sponge of any kind(unless you are prepared to clean it daily).

forgot to mention thats the down fall with that is the upkeep i have crystal clear water but needs cleaning every second day but i think it is worth it good luck with the tank
