how much excel to use on 260gal.


hi im setting up a lowtech 265gal tank. it will be heavily planted from day 1. about 200+ bunchs in plants total.

i have safetsorb 400lbs for substrates. got dry fertilizers for water dosing.
will be running 6x54W T5 HO bulbs.
all i left to buy is seachem excel.
do i follow the direction on the label?
should i get the 4L one since mine such a big tank?

by the way, is my lighting too much for a lowtech tank? will it cause algae issues? should i just do 4x54W?

Bunches of plants - stems? Get Anubias, crypts, java ferns and moss instead.

If you are determined to use Excel look at using Metricide 14 instead. It is a stronger solution of the same stuff in Excel and costs less. Use the amount it tells you on the label, 5ml per 50 gallons [1ml per 10 gallons] so 26ml a day.

Light depends on the shape of the tank. If it is tall you may need more light than if it is shallow. See the sticky thread in the Lighting forum.

If you buy Excel you might as well just drop $100 bills into that tank a few times a week. Definitely go with one of the generic gluts. If you want to try those higher requirement plants, maybe start with the 6x54 and if you run into (algae) problems then turn it down to 4x54.

Make sure you aren't using plants that are sensitive to glut.

Congrats on such a nice tank! I do respect your decision not to use pressurized CO2 if you don't feel comfortable with it. You're correct that it will reduce the trimming aspect.

I do agree with using Metricide 14 from a cost point of view. As far as excel, according to the label, dose 5mL per 50 gallons every day or every other day. On initial use or after a large water change, use 5mL for every 10 gallons. Keep in mind the substrate, plants, ornaments etc. will reduce the water volume which needs to be accounted for. Using daily dosing ONLY the 4L bottle should last about 160 days.

The lighting is another issue. The amount of light depends on too many factors to say if it's too much. I highly recommend you read this sticky in the lighting section. If you have questions not answered there Hoppy would be the one to ask.

BTW the vals may melt with excel use.

Maybe more. It's more concentrated. That is about the only difference besides being less than half the price. I'd have to do the math lol

You're looking at about $350 a year to dose with metricide 14, just buy a co2 rig....

That much? A gallon of Metricide 14 can be found for as little as $21 online with free shipping [fleabay]. A gallon is 3.7 liters or 3700ml. If you dose half as much Metricide as Excel that would be 13ml a day and the gallon would last for about 280 days for that $21. The stuff is definitely not as expensive as pressurized gas, I pay $15 for 10 pounds every other month for the 180 gallon tank. Metricide or Excel is not as good as CO2 but it is easy.

Good, glad you are getting some of the plants I suggested. I was picturing a tank planted with just Cabomba, Rotala, Ludwigia and the like. Nice plants but they take more work and light than the ones I mentioned.

Sorry, grabbed the wrong price, google price checking sucks.

It'll cost about $80 a year. Once again though: a co2 rig would be the much better investment. For 1 year's cost you could get a regulator
