If you do a
search you'll find lots of comments on Eco Complete ... & some slagging ... not sure how accurate as Carib Sea does provide a thorough analysis on the bag label ...
another irony is comparing EC to Aqua-soils & then complaining that water column fertilizers are still required (with EC)
😕
- I don't know any users of Aqua-soil that don't also expect to water column fertilize
🙄
Unlike the soil substrates, EC will last through many aquascapes & years of use with minimal texture change, if you have fish that like to dig or substrate "swim" (some loaches & the currently popular
Stiphodon gobies) I prefer EC over other sharper edged substrates (just sift through various substrates with your hands).
It's popular locally so I know many people that have used it & seem pleased with it's claims of "biologically" active - I've only set up EC tanks with cycled filter media so no comment on this aspect ... it doesn't smell like the dry gravels/sands etc so something happens during the processing.
Depending on transport/local storage it may be more or less "dusty" - although these fines settle fairly quickly, they'll reappear if major aquascaping is done so you may want to rinse before tank use if this has occurred (except of course, one of the nice aspects of EC is NOT having to prewash etc).
I've mostly used EC with a base layer of
Tropica Growth Substrate (or similar in the past) - unlike sand or most inert gravels, EC has a strong "exchange capacity" ie it will bind various compounds from water column & then release to plant roots, Seachem uses this same approach in their planted tank substrates.
Whether it's a worthwhile investment depends on local alternatives - "playsand" (not pretty, very dusty) used to be the cheap alternative substrate for aquaria but it's now only available (locally) with "antifungal/antibacterial" additives ... back to aquarium branded substrates & I can purchase EC for much the same cost.
Carib Sea is one of the most consumer friendly companies in the trade, you might contact them for information
🙂
Depending on types of plants, substrate depth of 5-10 cm is usually recommended; if you want increased depth perception through sloping of the substrate, then 5 - 15 cm variation is more pleasing.
For a large tank, shop around & see if you can get a volume discount.
If you look in the journals, there are some tanks done with very deep substrate gradients & some ideas for 'filler" substrates done up in stocking bags etc, also layering of the products such as Tropica's GS
Often in larger tanks, there are significant unplanted sand & rock areas, & plant substrate is only used in specific areas.
You may be able to buy plain crushed lava rock for a fraction of the price of eco complete.
only version of this locally available was rather large particle (think
large pebbles) & very sharp edged ... presently it would be a special order & not all that cheap either with shipping costs
