Nitrates are 0 (tested many times, other tanks read 30-100, so its good)
I had TONS of algae but cut it all out weeks ago, but it is slowly growing back
I believe the algae was causing 0 Nitrate readings!!
*i checked out your post, looks promising! HMF looks like a potential for me.... but the cost of the sponge and internal filter will run up some cash
My idea is to setup my 40G for CRS by:
-adding a Mosura Old Sea Mud and BT-9 to the glass floor
-pour 2-3 bags of ADA Africana
-add some frogbit, stems, and plants
-fill with RO water and dose with GH+ and aim for 5GH, 0KH, 100TDS
-add established sponge filter
-leave lights on for 1 week straight to stimulate algae
-transfer and drip acclimate 5 shrimp
if all is well after 2 weeks. transfer remaining 60 CRS/CBS and connect my established canister filter.
any tips on layering substrate (never did this) and what base bacteria to add to bottom
