Crinum thaianum and red tiger lotus water Sprite


Recommended Posts

I just order some crinum thaianum and red tiger lotus and water Sprite  I wanted to whether tropica premium liquid fertilizer would provide all their needs or do they need root tabs as I haven't had these plants before  any tips on ideal growing conditions

What is the water volume of the aquarium you are planning to put them in?

What is the stocking level (how many fish / what size fish)?

How frequently do you perform water changes?

How often and at what amount do you already dose Tropica fertilizer?

I have Tiger Lotus and a species of Crinum. The Crinum appreciates root tab, but my Tiger Lotus seem alright as long as other nutrients are balanced in the water column. I have kept Water Sprite before, and it seems to appreciate appropriate lighting.

I find that the crinum and tiger lotus want to feed from the substrate, so I use root tabs there. Water sprite wants to eat from the water column. The fertilizer listed doesn't have nitrogen so you'll need lots of nitrogen going in from fish food to keep the water sprite happy.

Hey @Cory,

As you mentioned above, Tropica Premium does not have N. However, once I checked, generally the N source in fertilizers (like Tropica Specialised version) commonly include ammonium, as it seems good for plant use.

Do you think ammonium in fertilizers can be harmful for fish and inverts, or is it safe? Would it have increased toxicity with higher ph and temps like the ammonia-ammonium form changes in general, or remains as ammonium no matter what? 

You probably had a chance to work on this one while creating easy green, so I would love to hear your opinion. Does N source in easy green also include ammonium as well?

I cannot decide which way to choose for my understocked densely planted tank. All in ones with N seems like a better option, but potentially harming fish/inverts seems scary. Hoping the answer would also help @Colu

Many thanks in advance,

We don't have any ammonia in our fertilizers. It's cheaper, but not better in my opinion. Ammonium is only that below 6.8ph. Above that it's ammonia. I don't believe this is worth the risk for the public, overdosing ammonia can lead to bad results. Can you get dennerle v20? I'd use that if I couldn't get Easy green.

Sadly no access to any of them. I may have Tropica, Seachem series, Sera and some domestic brands like "Creaqua" (which has two seperate bottles for Macro [(N) %1,6,  (P) %0,12,  (K) %1,24] and Micro [(Ca)%0,21, (Mg)%0,24, (B)%0,01, (Fe)%0,04, (Co)%0,0005,  (Cu)%0,007, (Mn)%0,047, (Mo) %0,002, (Zn) %0,002, Iodine(I)%0,018].

I could not see any explanation where Creaqua's N is coming from, nor if it is shrimp safe. They recommend turning off the filter for half an hour after dosing, which is interesting. Maybe it is a sign of ammonium, and filter may convert it to nitrate if dosed when it is on? I should email them sometime.

Sera ones are both expensive and not concentrated at all. I tried it before.

I am currently dosing seachem comprehensive twice a week and equilibrium with every water change for now, until the bottle ends. Aquasoil seem to do good for root feeders. No sign of N deficiency on any plant including floaters even tho I barely read nitrate, as expected. I was planning to go for Tropica Premium like Colu as well, after seeing premium containing ammonium. Seemed like the best bet.

What would you prefer in this scenario?

It a 50 gallon tank 15  x-ray and Columbian blue Tetra's and a couple of adult bristlenose plecos and lots of fry I do 50% water changes twice a week at the moment I add 5 ml of tropica premium liquid fertilizer   after each water change and my nitrates get to  15-20 ppm before water change

I think more nitrate buildup could benefit plants. I do not WC more frequently than once per week.

Because of the amount of waste my adult bristlenose plecos and  fry produce and the amount of food they consume that's why I do two 50% water changes a week  to make sure I don't get any ammonia or nitrite spikes
