Freshwater rodi filter? Help

I wouldn't use the ro, especially with rift lake fish, unless necessary to remove nasties from the tap water. What are the parameters of the tap water and tank water?

Unless your Water quality is really crap, then you don't need it in fact as others said there are trace elements in water that freshwater fish need, mostly reefers use RODI water since corals are pretty sensitive and don't tolerate fluctuations in water quality much, not only does weekly water changes remove the build up of nitrates but also replenishes the trace elements in the water, so if you want clear water upgrade biological filter and do bigger water changes, and most freshwater habitats in the wild are not crystal clear, i personally like a tinny bit of a color on my tanks but i do see the appeal in crystal clear water.

Good luck!

The water quality is pretty ****ty in Lowell. Not the best water sources and the building I purchased probably has the original plumbing from 1970. I do have live sand in the frontosa tank so I'm thinking that will help keep the water quality where it should be for them? What do you think

is it the live sand by Carib sea? if so i dont think it is meant for freshwater also the live bacteria in the bags are mostly dead and you really only paying for waste in your tank, maybe that could be another reason for water quality not being so good also the live sand doesn't do much for the Frontosa they need a Ph from 7.8-9 which is pretty high, check you Ph if its less than 7.8 then get some ph buffers if its higher thank 9 get something that will reduce it i personally i dont use the chemicals that reduce or increase the ph(mainly because they only work for a short time and you have to keep dosing which can be costly) i prefer a natural way of doing it, for example to increase ph use a filter mesh bag and put some crushed coral in it then put it in your filter this will increase ph and if you want to lower get some peat throw it in a filter mesh bag and put it in your filter this will lower ph, im in Malden and my house is pretty old i don't have problems with water quality, do you have an test kit? if so can you test your water straight from the tap after you dechlorinated it and post a picture up with the results? we can help you better like that and find out the problem, but if not i HIGHLY recommend you getting one its the MOST important thing in this hobby!! ill put up a link of the crushed coral and the test kit(its better to use the liquid test kits over the strips, since the strip are often very wrong and give very poor results) you can find peat anywhere they sell garden supplies(homedepot,walmart,lowes etc.)

Crushed coral im pretty sure your local LFS has it s it would be faster to buy locally than online
