Should i dose with these tank specs.

Hi everyone.

I was wondering if i should dose fertilizers for my 29 gallon tank. I would buy the fert pack from rex grigg's and follow the fert regime sticky posted here.

Here are my tank spec.

55 watt 9325 k bulb on an ah supply 55watt bright kit. This brings the tank to about 1.9 wpg.

Substrate is two bags of flourite black.

C02: two 2 liter coke bottles running on a mixture of 1/2 tsp yeast 2 cups sugar changed every other week.

The only thing i am worried about right now is the fact that i only have 1.8 wpg. But, i do not want to get another 55 watt ah supply bright kit because then i would have 3.8 wpg and with diy c02 which isnt always stable can cause an algae outbreak. Maybe i can add a home depot light that is about 20 watts?

Any help will be appreciated.

I would dose. CO2 usually makes plants grow a bit faster and while you don't have high light, you do have good lighting.

I haven't been successful growing Blyxa in less than about 3wpg (I know the rule isn't great), but you could try it. I would wait until you start dosing though.

I'll try and dose

Blyxa in less than 3 wpg Even if i add a home depot light, it will still be only 2.6 wpg.

Oh well, if i don't try, I'll never know.

I dont necessary need it to grow like crazy, just survive.

Btw, does anyone here dose ferts dry instead of a solution? I want to do it dry so i am thinking of getting this gram scale, not sure if anyone else has bought this type of scale before.

Thanks!

One that measures to 0.01 grams would be a better choice than one that weighs to 0.1 gram like you picked.

I seen some good prices on ebay with scales that will measure to 0.001 gram and will hold up to 50 grams.

Thanks for catching that Left C

I think this one is like the one you said:
http://cgi.ebay.com/LC-50-0-01-100th...742.m153.l1262
Its from the same person.

Has anyone on here ever bought from that person before? I know, its a long shot but worth a try.

I think that i will just stick with my 1.8 wpg and tilt the ah supply reflector to the front a bit.

That's an inexpensive scale that measures to 0.01 gram. It looks good to me.

0.01 grams scales are good enough for most purposes in our hobby.

You may need scales that measure to 0.001 grams for making reference solutions or other precisely needed weighed items.

Purchasing some weight boats will be helpful too.

Just buy small measuring spoons, it's so easy to dose that way.

Check out Green Leaf Aquariums for your dry ferts.

I bought a scale from the ebay vendor you mentioned earlier in post #4. For a cheap digital scale, it has worked great for me. I dose several tanks with dry ferts and I don't mind getting out a small scale to measure my doses. The best part is if it breaks, you can get a replacement for real cheap and don't feel bad for spending lots of $$.

Hm, but as Left C pointed out, .01 would be better than a reading of .1.

If i have a .1, would that mean a .86 through a .94 be the same because it rounds?

Hi Carole

Does Orlando sell half pounds, i only see on his website 1 pounds? If i did my calculations right, even a half pound of the 1/16th 3x a week ferts would last me ~5 years.

Whatever they were they were only $3.00 each. Plus, he's close, he's fast, and it's kind of like supporting your LFS.., not to mention he is just a great guy. Good luck with whatever you decide.
p.s. his tweezers are killer..

Is Plantex CSM+B really necessary? Its the only thing that is holding me back right now.

I think that i may need to save more money until i can buy ferts.

Yeah, his tweezers are killers, i saw you use them. Bam BAM and the plants are in the bucket

Any ideas on the .1 scale, .01 scale, and spoons.

I am using a 1/32 tspn. for the N,P,& K. It is a spoon that came with a salifert test kit. I might have an extra one around for you. I can look tomorrow if you like. As far as the scale, I bought one awhile back to use for Mr. Smiley. I am going to use it for the CSM&B. I bought one of the 500 ml bottles from Orlando to mix it up in. He told me 40g, and fill it up with RO water.That's another nice thing about buying from Orlando, he takes the time to explain his products to you if you need it.
here is the scale I bought.
