hey guys need help with this Ph problem i have. i bought a 20g rubermaid tub from walmart last week and i put about 15g of distilled water from food lion in it. then i added 1/2cup per gallon of reefcrystals to it and then put my 100watt heater and a maxi jet 1200 PH in there to mix and airate every thing. i got thinking and tested my PH, ammo,nitrites and nitrates and phos. and all were at 0ppm. except my PH was at 8.2-8.3.
now a day later i tested only my ph to see if anything changed and it did. it went down to 7.6 mabey lower its a weird color. almost like a ornge brown (very wierd) but this always happen to me . ever since i started this SW
hobby i have never had a PH of 8.2 last longer then a few hrs and thats only when i mix up a batch for a partical water change.
now i know u guys are going to say add buffers. i been that route too with my 55. i went out and bought a 2lb kent marine buffer and i slowy added that every time my PH got low. i dont want to go that route with this tank. i know its not normal to keep adding buffers every few hrs just to keep up the PH. plus when the PH fall to 7.4-7.6 and then just shoots up to 8.2-8.4 thats cant be good for the fish.
and all this happens in my rubermaid tub and my Aquarium. it dont matter where i do it. i though the LR
i have and the sand would buffer it naturaly but i was wrong. i guess. i do have ha power head pointed to the top for good surface ripple
what can i do to fix this problem. and what could be causing this to happen?
thanks again guys
