Retirement and forum shutdown (17 Jan 2022)
Hi,
John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.
I wish to thank John for his hard work in keeping the forum going.
With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.
I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.
If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.
I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.
I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.
Thank you
Darragh Sherwin
Proud new owner of RIO400, guidance needed please

I bought used tank, but never new anything about Ph and all the chemistry.
Tank came with ~40kg coral fragments ~5mm in size.
now I already have 4 fishes in it. (2 clown loach and 2 kuhli loach)
also 2 plants.
obviously previous owner had malawi fish in it, but never asked him if it will be ok to keep tropical fish in it.
Ph test kit is showing over 7.6Ph and the fish look stressed a bit to me.
I was advised to get rid of coral gravel and get something else than that.
Now if I want sand, can I get ordinary sand anywhere and gothrought rinsing and then boiling or do I get that strictly from the shop?
Other forum section members sujested aquatic soil.. is that just arround the plants or for the full aquarium bottom to cover? obviously will look black..
any other options that are not costing an arm and a leg?
the setu at the moment:
RIO 400 / Fluval FX5 / 300W Juwel heater / lighting blue & white
temperature 25-26C

however i hope you transfered whole tank contents into your place? a new set up shld be cycled properly first using many deifferent methods available these days. if the seller was using it up to the day it was sold to you then iy wld be great if you had water in it straight away and also operated the external cannister as the friendly bacteria in it shloud still be good and this in turn will help your new tank and water settle fast.
even using this method its best to let the tank cycle for a few days to 2 weeks. when cycling its not advisable to have any fishes in it yet.
we are working on too many assumptions here

in short if you transfered whole tank and contents like water and filter and media in it; you shld be fine.

i don't believe the bacteria survived the transfer..
my concern is the coral pieces are keeping Ph very high for the clown loach.. even piese of wood not helping.. so if I need to change, what are my options for gravel or soil for the base of the aquarium?

I'm nearly convinced coral gravel is raising it up to nearly 8 as the kit i have is only testing up to 7.6 or so... but it can be a lot higher. i will do that... have to bring the water to local aqua dealer.

However, if you aren't particularly wanting a lush plant growth I would suggest you go for something like silica sand to save you some money - I think you would need two bags of Manado for your tank (about €30 a bag).
I hear the playsand sold in Argos doesn't need anywhere near as much washing as the stuff coming from Woodies, but is rather more expensive.
The actual Aquarium Sand from LFSs is ready-washed and needs little washing as well, but - again - isn't as cheap.
You needn't be too worried about Clowns digging - they really get 'into that' once they grow somewhat, smaller ones don't cause that much difficulty in the digging respect.

Incidentally the bag claims it's for 120-360l tanks, although that might be spread a little thinly on the larger tank.
Yes, I use the Glenview playsand from Woodies - but it DOES take an awful lot of washing!!!
I'm assured the Argos stuff is much cleaner, so could well be worth the extra cost - but the best sand I bought was the Aquarium sand from a sponsor, that went straight in!
I was suggested to try the silica sand by a friend in the UK, but never actually found any over here (not that I tried very hard, mind).

There are others on the Forum far better able to advise you on this aspect (although if you want to know how to kill them - I'm yer man!).
T5 lighting is far superior to the older T8s - but your Rio 180 might already have this?
Reflectors are a real asset as well, and not overly expensive.

Did you bring the old water with you or is it all fresh water from the tap ?
I've used Glenview sand, but it is very dirty and will need alot of cleaning.
www.irishfishforum.com/blog.php?u=2644&b=102
Coral sand might not be suitable for fish that like to sift or dig in the sand.
If you try to cover it with other sand, then it might get mixed up when the fish start to sift or dig.

I personally would suggest removing the Coral fragments entirely and using either sand or inert gravel. You're absolutely right about the Glenview sand, it takes ages to get it clean (and they claim it is 'ready-washed').
Even for the purpose it's sold for (children's play pits) I think any child playing in it or with it would end up filthy before very long...but it is a cheap way to get tank substrate if you have loads of time and water to clean it.

I removed 30% of the coral chippings today, tomorrow will remove another 30% and the rest maybe next day.
Still trying to decide which way to go:
Monado all the way, without any other cover ( 2 bags by 25L should do)
Sand only... not a huge difference in price in the end I presume. ( not as good for plants, not as easy on cleaning either I heard)
I would like to keep 4-6 Ghost knife fish. hope they are going to be ok with Monado stuff.
appreciate all the help

i cleaned the filter last week, using aquarium water.
Also wanted to add, that media in my Fluval FX5 is ceramic rings, carbon, bacteria balls.
all my fish are hiding underneath the huge peaces of bog wood.
feeding well, but all my live plants are developing loads of small holes in them.. looks like they are eated y something, but the fishes I have:
4* clown loaches, 2* khuli loaches, 4* plecos (want to get 20 cardinal tetras, but not sure if my water is ready.
by the way no coral, sand, gravel or other stuff is covering the bottom of aquarium.
also for the plants, not sure if that affects.. 2* T5 lamps(white and blue)
hoping the blue one is not doing any damage.. I'm planing to relace it later..
Any ideas or advices are appreciated.

well at the moment the 2 species I would like to have in my tank are a bad idea..
20* cardinal tetra
5* black ghost knife
once knifes get bigger, they will eat the tetras right?
in any case none of these will live in Ph ~8

added 50L of monado
have 4 clowns, 4 plecos, 2 khuli loaches, 5neons, 10cardinal tetras, 2 pearl gourami's.
added 20-25 red cherry shrimp couple days ago, can't see any, so a bit of a waste. no idea which fish ate them.
2 more issues:
all my plants are falling in to peaces. they are loosing color and has a lot of holes in them. I started feeding cucumbers to slowns and plecos, also algae tablets.
other issues is the dirt at the bottom of the aquarium. anyone knows how to set the flow of external (FLUVAL FX5) in order to have cleaner environment?

thanks for reply.. like i posted I have 50L of monado down now. are these circulation pumps expensive?in regards to the dirt you have at the bottom of the tank there are 2 options regular gravel sphioning or get a circulation pump in the tank this will disturb the dirt at the bottom of the tank and help you fx5 to suck it up.do you have gravel down now for your plants or is it still a bare bottom ? to help the plants if you have gravel you could get some root tabs to put in beside the plants any pet store will have or get some plant food and add once a week.How long do you leave your lights on a day ? the rio 400 has t5 lighting if i am right this should be good to grow plants depending on the lights that are in.
I give some carbo stuff + JBL fertilizer every day. lights are on for arround 12h a day and you are right RE T5. I just didn't replace after this was ciclid setup. it has the very bright white and blue lights on.

blue fluorescent tubes are not intended to be planted tanks, replace as soon as possible, money for the electricity "go in the mud"
chris
ps
do you boil Manado before putting into the tank ?????
Hi there,
Thanks for the advise.
the T5 for the plants you are reffering to is the COLOR ones? any ideas for a good deals? i think it's 1200mm or so.
the monado I was just washing.. loads of it didn't sink, so I boiled them and the went down after. The shop I bought the monado from told me it's all safe to go straight in. I saw a lot of dust and washed second bag, but not the first one..

Anyway I have it down to 80 now, which is close to what I want for discus, when I can afford it

Do you think I need to replace both bulbs or just the blue one? Any ideas where to look?

Youre right, it has 2 1200mm T5 bars in the lighting unit. and i have reflectors on both. one of them was very rusty, cause of the limescale, so i replaced it.
You can see in the picture as the top is open, still most light goes down.
I'll have to go with special plant bulb when I find one for the price I can afford

As you hopefully can see from blurry picture and comparing to the previous one.. the big plants are now very small as I had to snip all the damaged leaves. I think cucumber is now making it better, not sure how long

not sure which route to go with new plants (planning to get more). go for anubia type so no fish will eat it or just start changing the stock so it would suit the planted aquarium..
