Water Changes and other questions?

[francis8]

its grea to have a forum here locally! thanks to my cousin!
i have 4 aquariums and have questions as to its condition below:

1st aquarium, nano FOWLR 20gallons with BackPack+UV+Skimmer:
Salinity : 1.016
Inhabitants : 2 percula clownfish, 1 maroon clownfish, 1 blue tang, 1 domino
Water : Yellow Bag Salt Mix from Cartimar
Condition : the fishes are thriving and they have been alive for more than 6 months now and i feed them 3 times a day and i never change the water since it evaporates and top it off with NAWASA Fresh Water

Question : does topping water weekly is enough to maintain it long term survival of the inhabitants?, please suggest what i must do

2nd aquarium, nano FOWLR 20gallons with BackPack+UV+Skimmer:
Salinity : 1.018
Inhabitants : 2 sailfin Tang that gew bigger and always fighting but they never get major injury and thriving, 2 clownfishes that never gets big, 1 gobby
Water : Yellow Bag Salt Mix from Cartimar

Condition : the fishes are thriving and they have been alive for more than 6 months now and i feed them 3 times a day and i never change the water since it evaporates and top it off with NAWASA Fresh Water

Question : does topping water weekly is enough to maintain it long term survival of the inhabitants?, please suggest what i must do, i placed 2 anemones from Cartimar and they just shrink in a span of 2 weeks and disappeared, i wanted to successfully put inverts but to no avail

shall i change the synthetic water into 25% NSW from Cartimar in a span of 3 days and put inverts?

3rd Aquarium, FOWLR 75gallons with SUMP, Crushed Corals, UV 9Watts Sterilizer, Skimmer Salinity : 1.018
Inhabitants : 10 kinds of clownfishes from cartimar, 2 cardinal fishes and 10 kinds of damsels
Water : 100% Salt Mix (yellow bag from cartimar)

Condition : the clownfished that i have bought from cartimar some of them have cloudy eyes but most of them are voracious eaters and none of them died, will they live long??

Question : i placed a beautiful carpet anemone and it just slimmed up after 3 days and i have to remove it bec it nearly contaminated the water and good thing none of my fishes got affected

i wanted to put corals and inverts and make it into a reef system, what must i do? increase salinity to 1.025? and make the system 25% NSW from Cartimar?

4th Aquarium, FOWLR 75gallons with SUMP, Crushed Corals, UV 9Watts Sterilizer, Skimmer Salinity : 1.015
Inhabitants : saddleback, cleaner wrasse, 2 big maroon clownfish, 1 bat fish, spotted angel, 2 pinochio (bullies), blue tang, gray powder tang
Water : 100% Salt Mix (yellow bag from cartimar)

Condition : i got some fishes from cartimar and mixed with the existing stock into tank and suddenly all the fishes are afflicted with ITCH, what i did was i applied hyposalinity at 1.0065 a month ago and fed the fishes with pellets dipped with garlic oil for 1 month and all ITCH disappeared right now i have moved the salinity to 1.015 now and will gradually increase it into 1.020, my fishes are very healthy now at 1.015 and eating voraciously at 3 times a day and i never changed the water but just topped it with a NAWASA Water weekly, do you think this is OK? but of course when i was raising the Salinity i have to add SALTMIX

Question : i really wanted to introduce inverts into the tank especially anemones and corals to make it more natural and beautiful, do i need to buy chillers or just change the water into 25% NSW gradually and wait for it to mature and introduce the anemone?

Please help

Welcome to Reef Philippines, Francis8. I moved your post so it can get the attention it needs, here in the FO and FOWLR section.

do you dechlorinate the nawasa water? forumers here use deepwell or RO water for topoff.
