Put it together with some airline tubing and I just use distilled water from walmart to keep the water level up.
Oh, ok! Thks!! The salt creep issue makes sense to me. The micro bubbles have mysteriously stopped. May've been the Protein Skimmer. pH was low on my tank when I moved it. We concluded it was the previous owners topping it off w/ distilled water. The pH has come back up nicely doing only SW
changes. I haven't been in a position to have to top it off as I've just been doing PWCs daily. I've heard just mix a teeny lil bit of salt into the distilled water to prevent the pH drop & it shouldn't whack out the salinity.
