Ph

[dudley moray]

Hi I'm having trouble getting my ph up it seems to hover around the 7.97-8.05
range, no matter how big a water change or what I dose
The only major change I've made is taking my bio pellets off line and replacing them with a poly filter I use aquavitro salt and dose with aquavitro chems any ideas ?

Check your testing methods. What are you using to test: probe, chemical test etc? What specific alkalinity supplement are you using? What are your calcium levels? Are you using GFO or other phosphate reducers? What is your alkalinity level?

My question would be: what's the problem of having that ph range?

And that would be the correct question

I kept an SPS tank for years with a PH in that range. I wouldn't sweat it.

I have an apex with ph probe I use aquavitro 8.4 and balance as well as ions and calcification the salt mix is supposed to give these levels
Cal-400-443mg/l
Mag1269-1403mg/l
Ph8.40-8.60
Alk3.2-3.8meq/l
Mine should be that as I only do 30%~50% water changes weekly and dose a teaspoon of the three (and a tiny bit of balance when ph get below 8) in fresh water top offs throughout the week I don't test most parameters any more only phosphorus and ph I do run carbon and a tablespoon on phoslock in a reactor
The reason I ask is because I'm having trouble with phosphate and I'm sure it's low ph allowing it to be released from the rock

I don't think that PH level will dissolve your rock. If your rock has PO4 it will leach regardless of the PH. I would increase you GFO amount and change it more frequently until you have the PO4 under control. As well I would look for the other sources of PO4.
