what is fidalin?
You are going to laugh.
My son was a baby 2 years back and Fidalin or Vidalin (Not sure about the spelling) is a pediatric liquid vitamin that is given to babies. This one has extra added iron, Lots of Vitamin C and a couple of different vitamin A's. It expired and my wife wanted to throw it away. I then thought "Lets see what happens in the tank as it is only vitamins". It had a very good effect. The swords and plants grew quicker and with much healthier leaves.
I just now discovered that it either buffers the pH very good or it raises the pH. I am adding pH down drops like crazy but it doesn't go down while it came down previously when adding only a couple of drops at a time over a week period. Now it stays at a constant 8. Previously I brought it down to 7.5 to 7.
Stop worrying about the pH and enjoy your tank. If the fish and plants are happy why can't you?
If you are desperate to lower the pH get some vinegar from the kitchen and add it drop by drop to lower the pH. The worst you can do is pH 4.something and you aren't going to be adding any phosphate which will increase your algae problem potential. The bacteria in the tank will deal with the acetate double quick. (In any case, some vinegar with the fish doesn't hurt the chips.)
I am kind of a perfectionist and worried that the fish might stress or a high pH will have a negative effect on plant growth since I added plants that are ideally for 6.5 or 7 pH. But on the other hand, they are grown in nursery conditions and not in natural pH conditions.
Maybe you should stop adding the Fidalin to your tank. Dirk se Druppels is the way to go
if you are worried about fish stress you shouldnt be adding expired medication to your tank, even if it is just vitamins... you never know what else is in there. vitamins oxidize really quickly, so they add all sorts of chemicals and preservatives to the suspension to stop that...
if i was you i would stop adding anything for a while, and do some regular 30 % water changes to try and get my water back to just plain water. then you can test your parameters and go from there.
the plants probably werent reacting to the vitamins but to the calcium or magnesium or similar in the "fidalin". with proper ferts your plants should get everything they need.
stop fidalin with your water paramaters...
once you start messing with pH, KH and GH its a long slippery slope downhill.
Yea, I stopped adding it. :-[
It was expired only by a month or two.
I PM'ed Dirk to hear what he has to offer for me that will give good plant growth and no negative effects on the setup as whole.
I have added a Alternanthera reineckii and read on the net they like a substrate full of nutrients. I am using pool filter sand and worried it will not work for them.
Does dirk have a wide range of stuff available?
you can get some root tabs and push them in all around the roots of your plants
Same ones that is used in potted plants?
Please don't say "ask local pet store" as they are absolutely useless with plants and help here in Bloem.
They don't even know what the names are of the plants they are selling. I go onto the net to look up.
yeah you can use the potted plant sticks, but aquarium root tabs are better
just break up the pot plants sticks and push them deep into the substrate.
I would rather like to get some that are specifically for aquarium use.
Anyone willing to help me?
I can deposit the money and then we can send it normal post.
I believe Panorama Pets ship\post countrywide.

They stock the Tetra root tabs, which I currently use in my Crypt setups. Use to use Seachem root tabs, but it's a little hard to come by and quite expensive. Otherwise, try Pet Stop SA.
Thanks a million.
I'm climbing in a bit late here but would like to add the following: what seemed like an interesting thing to do and then not such an interesting thing to is actually a brilliant thing to do - if done correctly! Let me explain. Many moons ago horticulturists at Kirstenbosch were struggling like heck with getting buchu species to root from cuttings. One day when I visited them they had cuttings galore in jars of liquid. I enquired and they explained they had finally cracked it - the cuttings were being soaked in a vitamin solution as a pre-treatment after which the standard procedure was followed - the success rate went from 1% to 80%! That vitamin solution was Superthrive - a vitamin B complex! I have since used a similar product on everything - from epiphytes to germinating seeds and especially on transplanted seedlings, cuttings etc. Plants love it! It is now a standard in my toolbox for growing difficult plants! Superthrive is muchos grande expensive but the substitute is quite cheap - Racing Pigeon Tonic! Yep that's right! Try it and you will be amazed - crypts especially love the stuff!
So Hendrik your good idea is actually a brilliant idea - just min us the other stuff they put in there. Stick to the B vitamins! And remember as with all supplements and feeding for plants - a little bit and often!
Thanks for your reply. So it seems I was sort of on the right track with my experiment.
What I did see is that it only ups the pH to round about 8 and then buffers it there.
It doesn't go higher and not lower. I add 0.3ml every weekend after doing a 20% water change and vacuum of substrate.
Think I will add less, maybe 0.1ml every weekend and then see if I can bring down the pH.
Some replies that I got was also to not worry so much about the pH. I think I must follow the advice.
It is stable at 8, the fish are eating and happy and the plants are healthy and growing much faster and the leaves are much healthier than before.
Sera also do a fertiliser tablet, of which I picked up a bottle last time I saw one at an LFS in P.E.
Most of the .za online shops should be able to mail you something similar. I regularly use Jungle (www.aquaria.co.za) based in Gauteng; if it's not in their shopping section, ask them, they can usually get it. There are several other e-tailors you can use of course.
