We would recommend keeping up to 4"/10cm of small to medium-sized fish in your system. However, depending on the type of fish, your filtration and your maintenance level you may be able to exceed this to a suggested maximum of 8"/20cm of fish.
However, this requires care and thought for the type of fish being stocked. We would advise you to read our FAQs for more details on stocking and for more details on how this program works.
We (as a family) want a 'natural look' aquarium. Biotope may be going a little far but avoiding orange gnomes and underwater fairy castles we'd like a picturesque living room tank with an interesting community of underwater creatures. I want to add plants purely for aesthetic and water quality reasons. I dont want them to grow quickly at all as this is a long term thing for me BUT I do want them to be healthy as the welfare of everything in the tank is very important to all of us.
I honestly dont know but I wouldn't trust bottled water for fish use as its not necessarily any purer than tap water. They add stuff for flavour which your fish really might not care for too much. I have no idea if they add chlorine and flourine to bottled water - it should say on the side but it might contain high phosphates too.
At least with tap water you get "natural" water with everything dangerous to humans removed and chlorine and flourine added which can be easily removed.
Again though, I dont know about special marine requirements much.
Just wondering (I know nothing of marine really) but wouldn't it be better to use boiled (or britta filtered) and treated water now to try to get the Amonia and Nitrite levels down rather than wait until tomorrow for RO ?
I used Protozin on my daughters goldfish which had whitespot when my wife bought them for her, it worked well although we lost two of them first due to bad lfs advice but they didn't die from the whitespot (no longer using that lfs after careful obversations of their fishes general health! )
They're refunding the delivery charge and getting me a new tank to replace the "old stock" one that I bought so its not all bad. Next week is school holiday so my wife is home all week to take delivery (she works in a school). I'm working today (just about) so I can use my day off next week after it arrives.
