    Yes...lower it to 1.025...I prefer 1.026...just add some RO water and test salinity after adding, until you get the level you desire..I assume the Salt Mix is at 26*C..as Temp does influence Salinity...

    Your temp is fine at 26, as long as its constant. Just add RO little by little until you hit 1.025

    Ya 1029 is a bit on the high side...try lowering it to 1025-1026 as the others have said with RO water.

    What are you using to test your salinity, a hydrometer or a refractometer? Reason I ask is that hydrometers are notoriously unreliable and could be giving you a false reading.

    Salinity is measured in ppt (35,5 ppt is normal) and it not temperature dependant.
    SpecifIc gravity is the measurement you give and it is temperature dependant.

    you will have to take out a litre or so of saltwater or so and replace it with RO water, if you just add RO it would be like top up. Or you can do a water change with lower salinity, just remember to do it slowly.

    Hallo i'm using a refractometer. Iremove about 13lit saltwater and add ro water. the reading is now at 1.025 and then left it for two hours and then did a water change. Left it again for an hour and test again, now it's 1.025 again and water at 26*C. Ammonia at 0, Nitrite at 0, Nitrate at 0.2, Phosphate at 0. The only problem i'm getting now is my NP pellet reactor. The pellets keep going to the top and get stuck on that small sif. I loosen the inlet pipe a little to reduce waterflow to the reactor and now it seems to work better but now the water is splashing the whole place wet. i'm so confused what to do now

    Out of intrest...and I do stand corrected..:p..it's my understanding that you have to go slowly with a Salinity increase and not so much when bringing you'r Salinity down...:blush: What would qualify as slowly...I would bring down over a period of say..2hours, depending on how high it is...and increasing I'll usually take a day...say every hour at a time...would that be considered acceptable or not...

    It is sort of ok. As long as that RO had the correct PH aa RO is normally far lower than seawater
