Frequent Problems with Picotanks

[JoshuAc00k]

Are there any common errors made by people with picos? I have a 2 gallon fluval spec with only zoas (not even a CUC). What are somethings I should watch for and the best way to avoid them. I've heard of tanks this small just going south and going fast and I want to try to avoid that as best as possible. Thanks for any help.

small tanks absolutely require an auto top off for evaporation. in such a small tank, salinity will fluctuate severely and hurt many corals and or fish.

yes, such a small volume of water will allow huge swings of parameters over small periods of time. You have to be real anal about topping off the evaporated water.

I bought a jbj 3 gallon and I had to top off twice a day and the temp swing too much. I never finish that project. I went with an 8 gal jbj but I got a chiller, ATO, and apex jr. Hopefully everything will be more stable.

Yeah. I have an ATO and the temperature has been very stable. So it seems lime I'm off to good start.

From my pico experience ~8G past tank I'd say in no particular order: temperature, evaporation, detritus build up and nutrient overload

Awesome parts though is salt mix last you forever, small "chunks" look like colonies. you can do water changes with a small bucket/pitcher, cheaper equipment overall.
