Anybody use tapwater (Prime'd) for top ups? With the glass tops gone, my evaporation rate is crazy, and i've spoken with several people in my area that us our tap water successfully in soft coral (reef) tanks, but have to do some crazy things to it. I will still buy the RODI (presalted) from my LFS until i decide/afford my own RO unit, but for the 5 gallons between changes, is tap water ok? Or is this a try-it-and-see type solution?
Thanks!
Update: my salinity i think got to high (SG was around 1.030) for my peppermint shrimp (havent seen either in a couple weeks), so i think i lost them. $25 meal for my crabs i imagine. Emerald crab has eliminated nearly all of the grape algae.
I have a green hairlike algae coming out of the spillway of the HOB filter and on some of the live rock. Snails dont seem to be interested in it. Put the skimmer back in and have been emptying a dark slime out every few days. I emailed Coralife CS to ask about the adapter to run the LED moonlights in my fixture but never heard back. Clowns appear happy as a fiddle.
Saltwater is hard.
