TMartins Posted June 28, 2021 Share Posted June 28, 2021 Hi everyone, I’ve setup a temporary tank in a Streilite tote (5 gallons) for Platy fry and my PH keeps dropping to 6.0 and below. I keep doing 50% water changes to bring it back up but it goes right back down. LFS told be to put base rock to neutralize the ph and that worked for my 20 gallon tank. I have Java Moss that I just got from the Co-Op and Water Wisteria from my 20 gallon.. My Ammonia, Nitrites and Nitrates are all 0. There is a seasoned sponge filter that I had in my 20 gallon aquarium. Currently I have 5 fry inside the tank because a bunch have died that think due to the ph. I’m pretty sure I’ve removed any dead fry. Link to comment Share on other sites More sharing options...
Colu Posted June 28, 2021 Share Posted June 28, 2021 I would add some crushed coral to buffer your water to provent pH swings 1 1 Link to comment Share on other sites More sharing options...
TMartins Posted June 28, 2021 Author Share Posted June 28, 2021 Is what I have from my LFS coral and they are just calling it base rock?? If it’s the same then should I just crush that?? Link to comment Share on other sites More sharing options...
tonyjuliano Posted June 28, 2021 Share Posted June 28, 2021 (edited) This is a carbonate hardness problem. If you can measure, you will probably see you have little to no measurable amount of KH. You can increase KH by adding baking soda, crushed coral or aragonite. If you go the baking soda “route”, a baseline recommendation is 1 teaspoon per 5 gallons of water (dissolve in a cup of aquarium water if adding directly to the tank). I don’t recommend any remedy be undertaken while the Fry are in the tank. They should be removed prior, and slowly reintroduced, as a rapid change in pH (from what they are already acclimated to) will surely kill them.

Spicy Reef Posted June 28, 2021 Share Posted June 28, 2021 (edited) I originally got seachem equilibrium for my plants and guppies because my water is so soft here in N seattle. I do not RODI, only carbon block filter and prime dechlorinator. So water after filter is 3.5 PH when I add the equilibrium I can easily get to my desired PH and ALK as well - for BOTH my fresh and saltwater... I think for a long term solution I might go Corey's rout of adding the crushed coral though. The equilibrium is working for now and I use about 1/4 teaspoon/ 5 gallons so it's cheap. Good luck 🙂 OH... ps Corey has a video on the crushed coral someplace on youtube. I'm not sure I would add it directly to the main tank, maybe to a 5 gallon bucket with a pump and see if it affects the ph first...

TMartins Posted June 28, 2021 Author Share Posted June 28, 2021 Thanks everyone for the info. I looked it up and what my LFS calls “base rock” is just “coral rock”. I crushed it up some and the ph is coming up. This forum is great for fish keepers like myself, I've searched for answers in the past in the forum and learned a lot. 1 Link to comment Share on other sites More sharing options...
quikv6 Posted June 28, 2021 Share Posted June 28, 2021 What is the KH of your tap water? If 0...you will most likely have repeated PH crashes. The crushed coral is a great suggestion. I do a crushed coral substrate along with the baking soda thing, to help keep my Mollies and Platies happy. They generally like harder water (GH) and a somewhat higher PH than neutral, speaking broadly. 1 Link to comment Share on other sites More sharing options...
