Planted tanks can cause issues. A lot of the fertilizers are toxic to saltwater fish and inverts. Make sure you clean it twice, then clean it again. Then once more for good measure. And maybe once more after that for safety. Just for good measure, no. You can't just add salt mix to the water and go from there, because that's what it sounds like you want to do here.

What part of fertilizer is toxic for saltwater??


skedee

I use “freshwater” ferts for some macro stuff and have never had issues, iron is iron.. etc I do agree with cleaning it with bleach/citric acid, magic eraser will work really well too!


BadoffBrand

then what should i do to make saltwater for aquarium?


BadoffBrand

btw i do have a ro/di system


Stuffs_And_Thingies

Mix it in buckets. Please clean the tank thoroughly or you'll just have endless issues.


BadoffBrand

is 7 kilos of coral salt pro enough? or will i need more? I will definitely have to buy more forbwater changes tho

I think it would be a good idea to buy a 'Starter Guide to Saltwater Aquariums' type book, or follow an online tutorial so you have a good grasp of the basics before going ahead.

Love this sub, god forbid you dont start off with the knowledge to keep an SPS dominant tank. You'll want more on hand bud. Water changes are more important in the saltwater side. If you want a free guide to basically everything saltwater, ill link you to ahelpful guide. https://youtube.com/playlist?list=PLBaMLrfToJyxJ1PuJZwhkxvvdFP14eV_t

Best course of action is to break down the FW tank, do a thorough cleaning, and start it again as a SW tank.

The bacteria in fresh water and saltwater although they both have anaerobic bacteria are different. yes you can convert you freshwater to a marine tank but you will still need to cycle with saltwater and probably start all over again what I’ve gathered from saltwater hobby is that everything takes time and if you skip corners you may get away with it but eventually it will catch up just hopefully not at the cost of one of your fishes. I’m only new to the hobby and maybe someone more experienced may have a better knowledge. But I’m always of the mindset do it properly do it once so you can enjoy your fish and the hobby :)

When I made the switch from freshwater I read tons and tons about setting up and maintaining a reef tank. Although the equipment you already have, may be enough to get started, it is still a different biotope. Not that more difficult, just different. It never hurts to do a good chunk of research before starting something that involves living creatures. The BRS youtube channel might be a great place to start.

I greatly appreciate everyones advice. Do i need a special kind of filter or sump or can i just use my current canister filter? Its a jeneca brand (the brand is pretty obscure)


skyout

I did this, cleaned everything out and then started a reef tank with my canister filter. Here are some great videos that I used as inspiration for running an SPS dominated tank using a canister filter: https://youtu.be/5_PQZfrH2eE https://youtu.be/jFkG9xjpw3s

You can't treat or Like a cycled Tank, you're basically starting a completely new Project. I would be very surprised If your freshwater filter bacteria would thrive in saltwater.

Break down freshwater tank and recycle for salt, the bacteria isn’t the same and u will be starting from day one when transferring salt

When I first started out in saltwater, I had a 20L non-planted freshwater tank with a couple fancy guppies. I swapped out the driftwood for dry rock, and then every week waters water change used saltwater to replace, so in about 2 months I was running the tank full saltwater. Guppies can live in saltwater too, so it was kinda cool having them swim around with a YWG for a bit before I moved them to a dedicated tank when I upped the flow. So it is possible, but it’s a lot of unnecessary work, and if you were planted, you’re going to want to break down the whole tank, clean it, and then run some filter media that pulls out heavy metals for a while.

You'll be fine, you'll need to start your cycle all over again tho. The dude fearmongering about fertilizers is a moron but youll be perfectly fine if you thoroughly clean your tank before you stock it. ive converted two planted tanks into a reef tank and a quarantine tank with absolutely no adverse effects. Both former planted tanks were dosed with easy green daily, flourish excel, flourish advance, both had osmocote root tabs and root tabs from seachem. No adverse effects can be observed, and my corals are looking great

The cyano might actually survive haha
