My water out the tap is about GH12 / KH5 / TDS ~320 and whilst in theory this is meant to be find for Cherry shrimp I lost the first two colonies I attempted to setup. For the third attempt I mixed 2/3 tap with 1/3 deionised water and this has proved fruitful and now I have a lot of breeding shrimp.
This is fine but I am have been looking at ways of cutting down the amount of plastic I am getting through (I am using Tesco deionised water at £1.5 for 2.5l) and potentially switching my other tanks to a similar mix.
I would love to use rain water but living on the very edge of Birmingham I daren't. Nearest LFS selling RO is quite a way away and whilst I believe there is a Spotless Water site closer, this would still be a pain having to travel every time I needed water (and I don't believe I can leave RO water to stand around too long?)
I keep looking at some RO units like https://www.pro-shrimp.co.uk/water-...mpact-130-ro-filter-system-4001615070392.html which at £60 don't seem too expensive but I am looking at how much these things cost over time. I am not on a water meter so the cost of the wasted water isn't an issue (although I am just switching the plastic issue to a water wastage one ). I know you need to replace the membrane every so often but I cannot seem to find replacement parts only generic ones. Is there anything else that is consumable and needs replacing?
Basically other that the cost of water, what is the running cost for an RO unit?
Also can you do anything with the water that is not used by the RO unit? I am guessing that this will be really really hard water so won't be useful for fish tanks?
